Best AR-15 Scopes and Optics: Tactical Reviews

Although its roots are military, the AR-15 platform has become one of the USA’s most popular hunting rifles. In the standard .223 caliber, it’s ideal for small varmints and predator control. The AR-15 is a reliable, light, and inherently accurate weapon. Still, we needed to find the best AR-15 scope to match.

When paired with the right accessories, the AR-15 is perfect for the job of bringing down a wide range of game. One of the most important accessories is finding the best AR-15 scope, depending on how you plan to use your rifle.

Best AR-15 Scopes: the Basics

Before we get into our buyer’s guide, let’s make sure you are up to speed on AR-15 scope basics. While we have some expert shooters that spend time on our site, many of our readers are also beginners who are very new to hunting/recreational shooting.

We want to make sure that you understand how scopes work and how they help you when properly paired. Let’s jump into some rifle scope 101.

What do the Numbers Mean?

Look, numbers can be confusing. Some of our editors here have a hard enough time figuring out how their electric bill is calculated, let alone understanding the magnification power of their AR-15 scope. Here’s what the numbers mean when looking at optics choices.

Power: The power of the scope is how far out you can see your target. Power is the first number you see when you look at scopes and you see a couple of numbers and a multiplier. Common numbers you may notice are 3×32 or 1-6×24. The 3 or the 1 in both series are the “power” of the scope. Higher numbers mean that the scopes are higher in power and give you maximum shooting distance.

If the number is a variable (like 1-6) that means that you can vary the power of the scope, giving you a much bigger range of power you can operate in versus a straight 3x or 4x. This is called variable power and is very common in today’s AR-15 optics. It may also come with a slightly higher price tag than non-variable scopes. Lower powered scopes are great for short to medium range hunting or operational range, while longer distance shooting will require a higher distance scope.

Objective: Scope objective is the second number in the series. A variable powered scope of 1-6×24 provides a 24mm objective. Objective is always measured in millimeters and refers to the lens size. Larger numbers mean bigger lenses. Bigger lenses are good for wide fields of view at a distance. They also allow for more light, making them good low-light hunting partners. Unfortunately, that also makes them bulkier. Take this into consideration if you plan to hunt at longer distances with your AR-15.

The best AR-15 optics come with adjustable objectives, making them easier to focus at longer distances. You can adjust what’s called the “parallax,” which will let you fine-tune your target at a much greater distance.  You need to worry about parallax when your power exceeds 10, and most scopes underneath that threshold have a parallax that auto-adjusts.

Reticle: The reticle of your scope is what most people refer to as the crosshairs of the rifle scope. It’s what you use to aim and point the gun at before firing. Red dot scopes have a red dot reticle, and green dot scopes have a green dot reticle. You get the idea.

MOA: MOA stands for “Minute of Angle.” MOA is an angular measurement that gets bigger with distance. Professional shooters use MOA to ensure that their groupings are extremely tight together, but MOAs have less applicable use for casual hunters and shooters. 1 MOA equals 5 inches at 500 yards. Someone with a perfect MOA can shoot a one-inch group at 10 yards. Think about this as the spread of three of the closest shot holes out of a 5/10/20 shot group.

Eye Relief Distance: This is how far you can hold the optic from your face comfortably while aiming. Keep in mind, AR-15s do have some recoil, so you want something that gives you enough room for kick-back so you don’t smack yourself in the face.


Best AR-15 Optics: a Buyer’s Guide

Navigating the sea of AR-15 optics can be extremely confusing. When it comes to buying the AR-15 optic of choice, the old saying of “you get what you pay for” applies here as it does for any other type of shooting gear.

Even with the cost being a significant factor, there are several things you should consider before equipping your AR-15 with the newest technology. We break it down into six sections of what we feel is most important when selecting an optic.

1. Planned Use

Planned Use Impacts Your AR-15 Optics Choice
How you use your AR-15 will impact how you equip your rifle.

The first thing you should be thinking about when buying an AR-15 scope is what your intended use is. Someone who is going to go out hunting with their AR-15 on a regular basis is going to have a far different need than someone who’s in the military or law enforcement. For some types of hunting and other tactical uses, you won’t even need a scope—a red dot unit or iron sights are perfect for short-range critter blasting. For longer range, you’re going to need the precision that only comes from a set of good AR-15 optics.

Scopes themselves come in two basic styles: compact military-type optics—many of them specifically designed for the AR-15’s military cousins—and more traditional hunting scopes. They both have their strong points. Military rifles are tougher, but hunting scopes offer better light gathering and, usually, more precise aiming systems.

What suits you depends on your planned use. A traditional scope makes a good all-rounder and has real advantages over open ground, but for controlling critters or hunting in the woods, a compact tactical unit makes a lot of sense.

AR-15 optics are not universal. You need to plan for how you intend to use your rifle, and sometimes owning multiple scopes makes sense. if you intend to use your rifle for tactical urban warfare drills in a survivalist training camp, a Red dot scope like an Aimpoint or a holographic scope like an EoTech are your best bet. Even for short-range varmint hunting, a red dot or holographic sight is perfect. For longer range, you want something with magnification settings that you can adjust depending on your windage and elevation, just like other long-range rifle scopes that may outfit a 30-06 or a .308.

Bottom Line: If you are a short distance hunter, go with a red dot scope or a good set of flip-up iron sights. Long-distance hunters should buy the best distance scope they can afford.

2. Budget

Budget Will Impact AR-15 Optics Choices
Your Budget Will Obviously Impact Your Optics Choices.

Let’s be realistic—budget plays into everything. If you have the budget to spring for a Leupold Mark 6, it may be one of the most important purchases you can make for your AR-15. Leopold consistently competes with bigger American companies like Trijicon. If the scope is the most important part of your rifle for you, then sink your money into it and let the scope reward you for the next 15 years.

If you are on a budget and don’t care where your AR-15 scope is made, then it may be hard to justify spending over $500.00 on a scope. The good news is that there are still some really quality scopes that you can pickup for a budget under $500.00 and save that extra hard-earned cash for additional rifle equipment. Make no mistake about it, the Trijicon and Leupold scopes are some of the best quality AR-15 optics that money can buy. But, if you don’t have a lot of experience with firearms, you are better off spending that money on additional ammunition.

You may also look into picking up a smaller practice rifle like a Ruger 10/22 to help you train. You will get far more out of your rifle if you practice with it repeatedly, and you will grow more comfortable with some traditional iron sights.

Bottom Line: If you’ve shot less than 1,000 rounds through your AR-15, your budget should be $500.00 or less.

3. Skill Level

Your skill level will also impact what type of optic you should buy.

Skill level is something that many beginners often overlook. They want to go out and buy the hottest scope on the market for their new “tacti-cool” AR-15. The history of the AR-15 goes deep, and the reality is that they are probably better off getting to the range and practicing with iron sights for a couple hundred rounds before thinking about what kind of AR-15 optic to invest in.

Someone that’s shot 200 rounds through their first AR-15 should only look at budget-friendly options. If you haven’t shot more than 1,000 rounds through your AR-15, you should think of spending less than $500.00 on your scope and sinking the rest of that money into ammunition so you can practice and get really good with your rifle. For intermediate shooters, sticking with a mid-level scope for distance or short range is a great idea. Stick with a Nikon for longer distances or an Aimpoint/Vortex product for shorter distances until you’ve practiced in the shooting range at least 30 times with your AR-15.

We mentioned it in the budget section, but beginners will get the most mileage out of their AR-15 optics choices if they get really good with iron sights to start with. Once you are comfortable hitting a target regularly with iron sights, then spending big money on quality AR-15 optics can make a lot of sense.

Bottom Line: Beginners should spend more time at the range and less money on optics.

4. AR-15 Optics Features

AR-15 Optics Features
You’ll want to buy the optic with the features that you’ll need.

Features are another area of consideration that you should be thinking about. Not all AR-15 scopes are created equal. Features can sometimes trump budget if you are buying your scope for a specific purpose. This is where you can justify spending the extra money. If you are going to operate your AR-15 in low-light areas, you will specifically want a scope that’s designed to let more light in. If you are planning on only using your AR-15 in the daytime, you have a little bit more latitude. Again, you can even stick with iron sights if you plan to do some closer range hunting and don’t need anything for distance.

If buying a red dot scope makes sense for shorter distances, you’ll want an AR-15 scope with a clear reticle. If you are looking at a red dot scope, the good news is that you can also purchase magnifiers to make the dot extend in distance, lessening the need for multiple optics. It’s worth noting that a lot of magnifiers won’t leave enough room on your AR-15 if you plan to run iron back-up sights or flip-up sights (BUIS).

Again, you also want to consider that you may end up buying more than one type of scope for your needs. If most of your shooting is short-medium range, spend your money on an AR-15 scope that can help you comfortably hit targets in that range, and spend less on a long-distance scope.

Bottom Line: You get what you pay for. Depending on your planned use, some features may be worth more to you than others.

5. Where It’s Made

AR-15 Optics Made in America
Some gun enthusiasts prefer optics that are made in the USA, even if they are more expensive.

Let’s face it: some people get pissed off when you mention buying anything manufactured overseas. People will say that the glass Nikon uses is “complete crap” or that UTG scopes are a “complete waste of money” because the glass used is manufactured in China. Look, we get it. But at the end of the day, sometimes people on a budget want a little bit of an extra edge.

A Bushnell, UTG, or Nikon can all be extremely versatile AR-15 scopes for the money—especially in a sea of versatile products. Are they at the same quality of a Trijicon or a Leupold? No.

But that doesn’t mean there isn’t value here for lesser experienced shooters just finding their way at the range. If you are a competitive shooter, you have no business in the budget section anyways, and there’s a good chance you’ve already found the best AR-15 scope for your planned use. Buying a cheaper product that’s made overseas by a company with a good reputation is far better than making an uneducated guess and buying a product you regret from a sub-par manufacturer.

Yes, we promote and like the idea of buying American made scopes for all of our firearms whenever necessary, but limiting yourself can end up handicapping you as well. One of our editors ran with a Ruger SR9 handgun for four months before switching to a more expensive CZ 75 SP-01 tactical, which ended up being a far better fit for him ergonomically, even though it’s made in the Czech Republic.

Bottom Line: Buying a Nikon, Bushnell, or UTG is OK depending on your skill level or budget. Buy what you are comfortable with and practice, practice, practice.

6. Type of AR-15 Rifle

The type of AR-15 rifle
The type of AR-15 rifle you have can also help determine what kind of optic you should pick.

The type of AR-15 rifle you have will also dictate the hardware you can equip it with. The good news is, mounting a scope is easy on most modern ARs. Unless you have an old-style Colt rifle with the carrying handle cast integrally with the upper, there will already be either a rail or fittings to mount one. The most common option today is a 1913 rail running the length of the receiver.

Even if you do have a carrying handle, it’s possible to mount a scope on it, but ergonomically that’s a nightmare – the sightline is far too high to get a good cheek weld, and canting the weapon causes significant accuracy problems. For hunting with an AR-15, always go for a flat-top receiver with a rail, this makes mounting an AR-15 scope a breeze.

It also makes sense to look at the cost of your rifle. Unless you have put 10,000 rounds through your Bushmaster and absolutely love it, why equip a $600.00 rifle with a $2,000.00 scope? Spend the money and upgrade the quality of your rifle first, then spend the money on the optics when it makes sense.

As noted above, carrying handles can limit your AR-15 scope options and make it less comfortable to shoot. There are plenty of flat top receivers and tactical rails that you can equip on your AR-15 to make them more flexible to equip.

Bottom Line: We prefer a flat-top receiver with a rail for most uses, especially for hunting. You can always buy a sling to carry it.


Best AR-15 Optics: EOTech Holographic Sights

Holographic sights are used primarily in close-quarters combat. They are used primarily by military personnel and law enforcement agencies. They have also gained an incredible amount of popularity over the last few years as a close-quarters sight for anyone that likes to hunt varmints at a closer range. The biggest advantage a Holographic sight has over a red dot scope is that the reticle is much bigger and the MOA is provided better range precision.

The field of view is wider, but there is no magnification used in most holographic sights. You can purchase a magnifier that will allow the scope to function at a greater distance. If you plan to stick to close quarters hunting or training, an EOTech Holographic sight should be your first choice. Keep in mind that EOTech is really the only true maker of holographic sights on today’s market – most others are red dot scopes designed to look like holographic sights. Let’s look at our Top 3 EOTech picks.


1. EOTech 512 Tactical Sight

What we like: Manufactured in the USA.
What we don’t: Nothing except the price tag.
Who it’s for: Intermediate to Advanced Shooters, Hunters, Law Enforcement/Military.

The EOTech 512 has pretty much set the standard for Holographic sights. If you can afford it, you won’t get a better holographic sight for the money. EOTech is made in the USA, which we prefer as we want to support American made companies.

Equipped with unlimited eye relief, you can get as close as you need to this AR-15 scope without worrying about any eye gashes from the recoil. We still wouldn’t recommend putting your face right up next to it, but you get the point: EOTech gives you some flexibility. The field of view is 30 yards at 100 yards at 4 inches of eye relief. This is more than enough to allow you comfort while hunting varmints at close range, or while training for any type of urban survival scenario.

There are 20 different brightness settings, allowing you to pick whatever is most comfortable for whatever your application is. The 512 boosts accuracy and improves target acquisition at a much quicker rate than standard conventional iron sights. The 512 is EOTech’s most popular model for a reason: it’s the battle-tested and clear-cut #1 choice for anyone that can afford the cost.


2. EOTech XPS2-0

What we like: Manufactured in the USA, small size leaves roomfor more mods.
What we don’t: the price tag.
Who it’s for: Intermediate to Advanced Shooters, Hunters, Law Enforcement/Military.

The XPS2-0 is basically the same as the 512 and has the same features, but it is square and takes up far less rail space. This allows you to co-witness easily with iron sights. The XPS sits lower than the traditional 512 and weighs less as well. This makes your AR-15 more compact than when you run a traditional 512.

The battery compartment is also more reliable and easier to access. The battery position is resistant to recoil impact due to its location, making it slightly less prone to damage. With the reduction of real estate, it occupies the rail of the rifle, allowing more flexibility if you choose to buy a magnifier that will extend the range of the holographic sight. The 512 also has AA batteries, making it slightly more compatible in a survival situation where you may not be able to find less compatible batteries.

When debating the XPS versus the 512, you need to decide which is more important: size and technology, or reliability and stability.


3. EOTech HHS I with Magnifier

  • EOTECH HWS Prestige Warranty - Comes with 10 year limited...

What we like: Manufactured in the USA,Convenient all-in-one package with magnifier.
What we don’t: Price tag; power on magnifier is fixed, not adjustable.
Who it’s for: Intermediate to Advanced Shooters, Hunters, Law Enforcement/Military.

We like the HHS I (Holographic Hybrid Sight) with the 3x magnifier due to the fact that it takes the guesswork out of buying a magnifier for you. No research needed, just pick the two of these together and run your rig. The reticle is specific to .223 caliber munitions, making it the perfect pair to an AR-15 for anything from close to mid-range.

The shortened base of the HHS also provides more rail room and is night vision compatible, making it a powerful package. The HHS allows for a true “two eyes open” shooting experience while getting the 3x magnification of a shorter range scope. The base is 7mm raised, which means that you can still have room for iron sights, even with the magnifier package installed.

Battery life is 600+ hours on the middle-range settings, making it one of the top of its class in battery life. The most interesting part of this AR-15 scope is that the magnifier “flips” to the side, making the holographic sight a great stand-alone application for close-quarters hunting or tactical training.


Best AR-15 Optics: Red Dot Sights

Have you decided you want a red dot scope? Navigating this maze is difficult, but there are a few stalwarts out there that stand out even when new technology is released. Red dot optics are completely different than EOTechs, which are holographic sights.

If you are looking for a holographic sight, then EOTech should be your choice. However, there are a few “red dot” optics that are definitely worth a look if you don’t have the budget for an EOTech, or if you have the budget for a top-end red-dot optic like the Aimpoint Pro.

The choices below are some of our favorites in the red dot category, and it’s hard to go wrong with any of them.


1. Aimpoint PRO Rifle Optic

  • Features 10 brightness settings including one extra bright for...
  • Up to 30,000 hours (over 3 years) of constant operation from 1...

What we like: Reliability, reputation, ease of install on various firearms.
What we don’t: Price.
Who it’s for: Beginners through advanced . All around excellent Red Dot scope.

Aimpoint’s PRO is the most expensive AR-15 sight here, and there’s a reason for that. It’s a fully mil-spec scope, designed for military versions of the AR-15 platform, and it’s outstandingly high quality. The price might seem high for a non-magnifying red dot sight, but if you’re planning on snap shooting at close range and want a scope that’s as close to indestructible as you can get, this is the one.

At only 4.5 inches long and weighing 11.6 ounces complete with mount, this is an extremely compact device. It’s also as rugged as it gets, with a high-grade aluminum body anodized in black or coyote. It comes with a mount, which has a removable spacer; use the spacer to get co-witness with the iron sights on a flat-top AR, or remove it for a lower profile on weapons that don’t have a straight-line stock. The mount itself is rock solid and has a large knurled knob for quick release.

This sight has soaked up a lot of combat experience, which can be seen in the clear rear cap. If you need to take a shot and don’t have time to flip up the built-in caps, you can still see the red dot through the rear one; with both eyes open, your brain will superimpose the dot on the target and you can still get the shot accurately. If you’re predator or varmint hunting in dense cover, that’s quite a handy feature.

Optically, this AR-15 sight is very bright despite its 26mm objective; the lenses are high-quality and very well coated. The reticle is a 2 MOA red dot with ten brightness levels; four are night vision-compatible. You can also mount either an Aimpoint 3x magnifier or a night vision module in front of the scope to extend its capabilities.

Aimpoint has opted for an always-on illuminator, but that isn’t a problem with a three-year battery life, and it means the dot is always lit when you need it. The battery cover and adjustment caps all have retaining lanyards to prevent loss. The attention to detail is just incredible. It might have a high price tag, but the Aimpoint PRO is excellent value for the money.

What we like: Vortex reputation, price, features.
What we don’t: Manufactured overseas.
Who it’s for: Beginners through Advanced: Quality Red Dot scope for shooters on a budget.

Another tactical-style AR-15 scope, this one is even more compact than the Bushnell; it’s 5.6 inches long and weighs just 7.2 ounces. It’s also a non-magnifying sight and it’s heavily optimized for close-range shooting. The cantilever mount lets you co-witness the iron sights on a flat-top AR-15, and it’s also compatible with night vision equipment. Eye relief is non-critical, as this is a very easy scope to use with both eyes open. It’s ideal for dealing with fast-moving critters at shorter distances.

The StrikeFire II has a 30mm tube, so if you want, you can change the cantilever mount for another single-ring one. It’s well-sealed and waterproof and feels very sturdy for such a light unit.

With no magnification and a 30mm objective lens, you’d expect the StrikeFire II to give a good, bright image, and it doesn’t disappoint at all. The aiming mark is a simple red or green dot that has ten brightness settings. The dot itself has a 4 MOA diameter, so this isn’t your first choice for long-range paper punching, but it’s perfect for the sort of snap shooting the sight was designed for. Adjustment is through clicky turrets with half-MOA increments. A nice feature is a 12-hour auto shutdown on the illuminator, so if you forget to turn it off when you’re finished hunting, it won’t kill the battery.

The Vortex StrikeFire isn’t at all expensive for a tactical scope, and it really is impressively small. It also comes with a quality mount and built-in flip caps, so it works out to be a great value AR-15 sight.

What we like: Cost, Reliability, Popularity, & Testimonials.
What we don’t: Manufactured overseas.
Who it’s for: Beginner to Intermediate shooters/hunters.

The Bushnell TRS-25 is the original budget red dot scope. It’s the perfect short-range red dot scope for a beginner on a budget and is one of the most widely purchased beginner optics for an AR-15. This is one of the best AR-15 scopes if you are just starting out and are looking for something basic.

One of the reasons we love the TRS-25 is that it doubles as a red dot scope for other firearms you may use. You can easily toss it on a shotgun if you plan to do some small game hunting on the weekend at a closer range. Some shooters even choose to mount the TRS-25 on their handguns to get a better aim for competition shooting.

This is one of those few areas where “you get what you pay for” actually goes the extra mile. If you are just starting out, or even if you are an intermediate shooter on a budget, the TRS-25 has several features that are useful for a budget-friendly option. One of the main benefits is that the scope can be used with both eyes open and the eye relief is unlimited. It operates about as close to a EOTech as you are going to get without the hefty price tag. It mounts up to any Weaver-style rail or Picatinny rail.

The TRS is 100% waterproof/shockproof/fog proof, making it a durable optic. Bushnell may not be on the same quality level as Trijicon or Leupold, but this is a solid red dot unit for a fraction of the cost of some of the more expensive models.


4. Sightmark Ultra Shot

Product

Sightmark Ultra Shot M-Spec Reflex Sight

  • Digital Switch Controls
  • Variable Reticle Brightness With Night Vision Modes
  • Cast Magnesium Alloy Housing With Protective Shield
  • IP68 Waterproof Rating - Submersible To 40ft

Details

  • Digital Switch Controls
  • Variable Reticle Brightness With Night Vision Modes
  • Cast Magnesium Alloy Housing With Protective Shield
  • IP68 Waterproof Rating - Submersible To 40ft

What we like: Cost, Quick detach weaver mount, parallax corrected lens.
What we don’t: Made Overseas.
Who it’s for: Beginners through Advanced: good for shooters in every category.

The Sightmark is a “middle of the road” AR-15 scope when it comes to quality. It has a few things going for it, like the fact that the battery life is good and it’s waterproof up to 40 feet. Like the EOTech 512, it has unlimited eye relief, making it the perfect application for an AR-15 in close quarters.

It has a digital switch control with 12 total settings. Half the settings are for use during the day, the other half for when there is minimal light. The shock-proof frame will withstand recoil from up to .50 caliber rifles, making it extremely durable. The Sightmark sight is a great option if you are looking for a “jack of all trades” budget holographic sight. It can be used for competition, hunting, and tactical needs.

While we still prefer the bells, whistles, quality, and manufacturing base of the USA for the EOTech 512, the Sightmark Ultra Shot is a great value holographic sight for the money if you are on a tighter budget when buying an AR-15 sight.

  • 1 x Megapixel
  • Red/Green t-dot
  • 5 brightness settings
  • Multi coated Optics
  • Integrated mount
  • Tactical riflescope with 1x power and 32mm objective lens

What we like: Cost, reticle color options, integrated mount.
What we don’t: Manufactured overseas.
Who it’s for: Beginners through Advanced: great Red Dot on a budget.

This is much more of a tactical style sight and it’s very different from a conventional hunting scope. It’s a non-magnifying 1×32 unit designed for rapid target acquisition at closer ranges. If you want to do some varmint control around a farm or in the woods, this is basically made for the job.

Bushnell has packed the sight into a cast aluminum body that’s just 6.75 inches long and weighs 15.6 ounces, complete with integrated Weaver rail mount. It’s nitrogen-filled, fully sealed, and shockproof; in fact, it’s amazingly rugged. Emergency battle sights are cast into the top of the body. These AR-15 sights are a military feature designed for use if the scope breaks—they first appeared on the British Army’s SUSAT Trilux sight—but they’re also handy for snapshots at close range.

The scope itself is amazingly bright—the 32mm lens pulls in all the light the non-magnifying lenses can use—and gives a clear, distortion-free picture. Aiming is done through a T-bar reticle with a central dot. You have a choice of red or green illumination, and the dot itself can be adjusted from one to ten MOA. That lets you choose between pinpoint longer-range accuracy and a bold dot for rapid aim closer in.

If you want a very compact AR-15 scope for close to mid-range shots, this is a very good choice. The cost along with its features make this a great value for any shooter looking to improve their accuracy.


Best AR-15 Optics: Short Range

If you are on a budget and need to look at optics on the cheaper side, don’t be afraid to give the top picks made by Burris or Nikon a try. These are decent AR-15 scopes, especially for beginners and intermediate-level shooters.

If you are just starting out, you should focus on range time, iron sights, and a cheaper AR-15 scope. You shouldn’t be focused on spending all your hard-earned cash on an AR-15 optic unless you plan to grow into it.

Nikon optics shouldn’t need any introduction; their quality is well known. That applies to its AR-15 scopes as much as to its camera gear, and the P-223 adds a generous dose of innovation as well. This series is designed specifically for AR-15 rifles, and Nikon has put a lot of work into creating a scope that’s both compact and highly effective.

The P-223 Carbine has a conventional hunting scope layout, but manages to pack a 3×32 format into a unit that’s just 8.1 inches long and weighs 12.2 ounces. That makes it ideal for short, light AR-15s. You can add a very impressive optical capability without much impact on handling.

The P-223 Carbine has very impressive build quality, as you’d expect from Nikon; the tube is waterproof, shockproof, and nitrogen-filled, while the optics are fully multicoated to give very good light transmission. The 32mm objective and low magnification produce a bright sight picture, too, although the 3x power is best for shots at under 300 yards. It does give a wide field of view, and the picture is distortion-free right out to the edges.

Nikon equipped this AR-15 scope with a bullet drop compensating reticle calibrated to the .223 round; the main crosshair is set up for a 200-yard zero, with additional marks for 400 and 600 yards. The zeroing turrets are large and easy to use, with positive quarter-MOA clicks. If you’re looking for a solid, affordable, compact scope for mid-short range shooting, this is a solid budget pick.

What we like: Quality, Vortex brand, size.
What we don’t: Price tag, battery life of only 250 hours at maximum brightness.
Who it’s for: Beginners through advanced; good for short distances with red dot features.

You could argue that this should be in the red dot category, but this little AR-15 scope combines red-dot technology with short-range distance magnification. Designed for .223 rifles, this slightly larger tactical scope adds 3x magnification and some more reticle options; it still works competently at close range but can push out a lot further than the StrikeFire II. It’s also more expensive, but that reflects its quality and features.

Vortex created the Spitfire with the AR-15 platform in mind, and they’ve done a great job of cramming stacks of performance into its small body. The scope is just 5.5 inches long and weighs 15.4 ounces. The secret to its performance is the optical design: instead of lenses, the magnification work is done by a prism, allowing for the same performance in a much shorter optical path. The reticle is etched directly onto the prism, so there’s no chance of breaking it without destroying the whole scope in the process.

The reticle itself is the EBR-566 Enhanced Battle Reticle, with a partial aiming circle round the top of a vertical line. The upper part of the line is marked with aiming points for ranges out to 500 yards—a long shot at 3x magnification, but this aiming system should cope. There’s a choice of red or green illumination at five different brightness levels.

Its 30mm objective lens gives the Spitfire a very clear, bright image and a wide field of view. Adjustment is by half-MOA increments through elevation and windage screws with protective caps. A fast-focus eyepiece lets you get the reticle nice and sharp. This is a very solid and highly capable compact hunting scope that operates out past the maximum responsible hunting range of a .223 AR-15.

What we like: Everything. This is the best short-range scope on the market.
What we don’t: Price—your wallet will scream.
Who it’s for: Advanced shooters—more value for beginners in practice with their rifle.

ACOG stands for “Advanced Combat Optical Gunsight.” Trijicon ACOG scopes are used by many military and law enforcement personnel for advanced tactical training. Make no mistake: this scope is for people whose lives may depend on their rifle at some point.

If you want the best, you have to pay for it. Some people have a hard time justifying spending as much money on a scope as they probably did their rifle. But if you are the type of person that’s built their own AR-15 and spared no expense, the Trijicon ACOG 4×32 is worth it.

The ACOG 4×32 operates battery-free and has a day/night illuminated Chevron. This acts the same way as a dot scope would, without worrying about the battery. The Fiber Optics provide daytime illumination, and a tritium phosphor lamp provides nighttime illumination. The scope is made of military-grade aluminum and is both waterproof and fog proof. The tritium lamp that provides nighttime illumination is warrantied for up to 15 years, and the Trijicon lifetime warranty is something only the best in the business provide.

The Trijicon ACOG is a tactical combat AR-15 scope. It is meant for training at 400 yards and closer in. It’s not meant for long distances and again, if you are a beginner, save the money here and get a Nikon 3×32. If you are an advanced shooter and can afford the price tag, you probably already know what you are getting by picking one of these up.

What we like: Trijicon brand, durability, warranty.
What we don’t: Nothing but the price. Yikes!
Who it’s for: Advanced Shooters.

We’ve added the VCOG to our list (VCOG stands for Variable Combat Optical Gunsight) because this is the yin to the ACOG’s yang. While the ACOG is best for short-to-medium open range distances, The VCOG is something that can “do it all.” The power ranges from a variable 1x to a 6x with a couple easy clicks, making it adaptable and more evolved. The VCOG comes with a hefty price tag but is well worth the cost for people that depend on their scope for advanced tactical purposes.

While we have this scope in our “short-range” category, it can easily function as a medium-range scope if you are good with the smaller objective that the 24mm diameter offers. This scope is excellent for any type of tactical training and is used by many members of the military. Eye relief is at 4 inches, which is a little further out for some people, so that’s worth considering if you are looking for a scope without relief limitations. One of the biggest pros that this scope offers is the amount of abuse it can take without losing its zero. It’s designed to take a beating and stay true to the target even through intense conditions.

If you are looking for what’s considered to be the best scope on the market today, the VCOG is your answer—if your wallet can handle the price tag. Keep in mind that this optic is probably a better fit for people that are more advanced in their firearms training. As we’ve emphasized before, training with your AR-15 and iron sights or a cheaper scope should be your first priority if you are a beginner.

What we like: Quality, Vortex brand, size.
What we don’t: Length leaves less room on rail for other mods.
Who it’s for: Beginners through advanced.

Vortex Optics have made a name for tactical-style AR-15 scopes, but if you prefer a more traditional look with the same technology built in, the Strike Eagle looks like an attractive option. It’s still compact, too, and its zoom capability makes it great all around. Designed for the AR-15, it guarantees fast target acquisition at all ranges and pinpoint accuracy.

The Strike Eagle wraps around a standard 30mm tube, machined from a single piece of aviation-grade aluminum. The tube is nitrogen-purged and fully sealed, so you shouldn’t be bothered by fogging; the lenses are fully multi-coated to minimize reflection and make the most of the light gathered by the 24mm objective.

With the scope being tailored for the AR-15, Vortex has fitted it with a bullet drop-compensating reticle calibrated to .223 rounds. A three-post system surrounds a central illuminated aiming mark, which features a partial circle for snapshots and a vertical line graduated in 100-yard increments for easy holdover. The range lines go all the way out to 600 yards, and in good light, this scope will handle that very competently. The reticle itself is etched into the glass for durability; there’s no chance of it breaking under the stress of repeated recoil.

As you’d expect, the weak point of the Strike Eagle is in low light conditions, but the zoom range helps compensate; drop the magnification to 3x or lower and you can keep shooting well into the twilight.

Vortex has gone for traditional adjustment screws with protective caps, rather than turrets. This keeps the scope’s profile low, and the reticle means there’s no real need to dial in adjustments once you’ve zeroed. The focus ring is standard, mounted at the front of the eyepiece, and has a large stud for easy operation. Overall, this is a very high-quality scope that easily justifies its price and spot on this best AR-15 scopes list.

Details

  • Red-green Ballistic Armalite Rifle reticle
  • 10 LED Illumination settings
  • Parallax free at 100 yds

What we like: Price, Burris warranty.
What we don’t: Manufactured overseas.
Who it’s for: Beginners through advanced; labeled as the poor man’s ACOG.

Another tactical AR-15 sight, the Burris AR-332 is a 3×32 format designed for military and law enforcement use, but it’s also great for close to mid-range hunting. This is a high-quality scope with a lot of useful features, and it deserves a close look if you want to put together a good all-round AR. It technically qualifies as another red dot scope, but we like it for short-distance due to its magnification power.

The AR-332 is 5.3 inches long and weighs 14.2 ounces, including the 1913 rail mount. The body is sturdy and cast from aircraft-grade aluminum, with a tough anodized finish. The top and sides of the body are fitted with short 1913 rails, so you can fit lights, lasers, or even a CQB sight.

Controls consist of two zeroing dials that work in half-MOA increments, and a large rotary knob to manage the illumination. The scope has a choice of red or green illumination, with five brightness settings for each.

Burris has equipped the AR-332 with a BDC reticle, consisting of a large quick-acquisition ring surrounding a cross with central aiming dot. The lower arm of the cross is made up of holdover dots calibrated to the .223 round, out to 600 yards. The reticle is extremely easy to use and is highly visible in all conditions.

This is a very competent tactical scope, rugged enough to last a lifetime and offering excellent performance in all conditions. A combination of a bright, clear image and well laid out reticle makes for accurate shooting to the AR-15’s full range, and it’s still light and compact enough to give you a manageable rifle.

What we like: Cost, smaller size.
What we don’t: Manufactured overseas.
Who it’s for: Beginner to intermediate shooters.

Another scope designed specifically for the AR-15, the compact, high-quality Bushnell adds the bare minimum of bulk to your weapon. It’s a tiny 1-4×24 unit, but its small size doesn’t get in the way of performance. This is no light bucket, but it can still be effectively used in low light conditions.

Bushnell kept the Drop Zone-223 usable by going for relatively low magnification; even with the small lens, you can get a bright picture in moderate twilight at full power, and dropping the magnification to x3 will keep you shooting as long as there’s any daylight at all.

Although it’s small—9.1 inches overall—the Bushnell is solidly built from aviation-grade aluminum, weighing in at a chunky 16.9 ounces. The tube is nitrogen-filled and well sealed against moisture and dirt, with a tough anodized finish. The BDC reticle is calibrated to .223 caliber, with a 100-yard zero and aiming marks every 100 yards out to 500.

The zeroing turrets are target style, with 0.1-mil increments. A tenth of a mil is about 0.32 MOA, so it’s slightly less precise than the other scopes, but the difference is insignificant.

This is a very neat little AR-15 scope that performs much better than its size suggests. If you want a compact hunting optic and you’re happy to lose some magnification in twilight conditions, this Bushnell will do a great job, especially for beginners with a small budget.

What we like: Multiple illumination settings, PCL lever.
What we don’t: Cost compared to the Drop Zone 223.
Who it’s for: Beginners to intermediate shooters.

One drawback of smaller AR-15 scopes is that the sight picture is less bright around dusk and dawn. That can become a problem: often you can see the target, but the reticle is hard to make out. To let you make those shots, Bushnell has produced an illuminated version of the 223 1-4×24.

This is basically the same scope, but with a red illuminator added to the reticle. A very nice touch is Bushnell’s new illumination control system. There’s a throw-down lever mounted on top of the eyepiece that lets you change the reticle brightness very quickly. This is the perfect sight for anyone who prefers a small scope but wants to get every available scrap of twilight performance out of it.


Best AR-15 Optics: Medium Range

A medium range AR-15 scope is where we really start to differentiate the optics choices for a tactical rifle. It becomes more difficult to use them up close, especially with eye relief starting to come into play. If you are a beginner, you should be looking at the shorter range scopes or the red dots to start you off unless you know you will be hunting or using your rifle at a medium distance (think 200-400 yards out).

These make a great pairing if you plan to run a dual scope setup where you swap out for longer distances. Most of the effective “one size fits all” type scopes for beginners are in the short-range category. The scopes below are all great for medium distance use and are extremely valuable if you plan to use your AR-15 hunting small game.

What we like: Cost, use for other rifles.
What we don’t: Made overseas, more for medium-long range distance.
Who it’s for: Beginners through advanced.

The Prostaff 3-9×40 is another great example of Nikon quality. This is a versatile hunting scope that won’t break the bank but gives you excellent optics and solid build quality.

The Prostaff range is extensive and contains a wide variety of AR-15 optics, but for hunting with an AR-15, the 3-9×40 zoom model is the perfect jack of all trades. Its 9x maximum zoom works past the limits of the rifle’s range, and the lens gives good light-gathering capability without too much of weight and bulk penalty. It’s also a rugged, simple scope with not much to go wrong.

For a scope with these specifications, the Prostaff is pretty compact, at 12.3 inches long and 13.7 ounces. The optics are multicoated, and the tube is shockproof, waterproof, and nitrogen filled. Zeroing is through screws under protective caps; adjustment is in quarter-MOA increments and has a nice positive click. Zoom from 3x to 9x power is controlled by a ring in front of the eyepiece and is easy to operate.

Inside you’ll find Nikon’s BDC reticle, with a series of range circles that allow you to quickly aim off for distance. The sight picture itself is clear and bright; in twilight conditions, you can easily use up to 5x magnification. This AR-15 scope is easily capable of handling shots out to the AR-15 platform’s full effective range and makes a great choice for hunters who want a usable zoom capability.

If you like the features of the little Bushnells, but want more magnification and light-gathering ability, this is the best AR-15 scope for you. It has the same rugged construction and quality optics, but nearly three times the objective lens area and a higher zoom range.

On this sight, Bushnell has reverted to quarter-MOA clicks on the very precise turrets, and they’ve also added a parallax turret on the left of the tube. Combined with the rapid focus eyepiece and a nice smooth zoom ring, this all makes for an AR-15 scope you can set up quickly and easily – and it holds its zero once you’ve dialed it in.

The larger lens gives you a much brighter picture in low light conditions than its little brother, and that makes the extra weight and bulk worthwhile: this scope is 12.2 inches long and weighs 21 ounces. It’s outstandingly solid and feels like it’s worth a lot more than most optics in this quality range. If you don’t mind running a 2 scope setup, with one for medium to longer distances and a red dot or holographic sight, then the Bushnell Drop Zone is a perfect pick for best AR-15 scope.

What we like: Cost, Cost, Cost.
What we don’t: Manufactured overseas, quality is hit or miss.
Who it’s for: Beginner to intermediate shooters, or people on a tight budget.

If you’re looking for a budget scope that’s still packed with features, the UTG BugBuster is an excellent choice. It is compact and has all the capability you need to turn your AR-15 into an excellent hunting or tactical rifle if you don’t have a lot of money to spend.

The Bug Buster has a rough, sealed tube that’s filled with nitrogen to eliminate internal fogging. The objective lens is emerald coated to maximize light transmission, and the sight picture is amazingly good for this price—there’s hardly any distortion around the edges, and the Mil-Dot reticle is a great tool for both aiming off and judging distance. At higher magnifications, the brightness did begin to fade, but that’s inevitable in a scope this size. At 4x magnification, it’s perfectly adequate for shooting around dusk and dawn, and as light levels increase you can crank the zoom up, too. The zoom ring has a large stud for easy use, and the settings are clearly marked on the tube.

Zeroing is via large turrets with a similar zero-reset system to the Nikon’s. There’s also a third turret on the left of the scope which controls the illumination. You can select either red or green illumination for the reticle, which gives an outstanding sight picture in low light or against a dark target.

Finally, the BugBuster comes with a useful selection of accessories, including quick detachable mounts, a sunshade, and flip-up caps. This all adds up to an excellent value package. Quality may not always be spot on, but for the price, it’s easy to replace if you encounter a defect 6 months down the road. While this wouldn’t be our pick for major tactical operations, it serves the purpose of short-medium range hunting on a budget very well.

Offering higher magnification and better light-gathering ability than the BugBuster, with the same extensive range of features, this scope is perfect if you hunt a lot around dawn and dusk. It is a bit larger, at 14 inches long and 25.6 ounces, but the extra performance is worth it.

The Compact’s 30mm tube is built on its True Strength platform to ensure it can take a few knocks without losing zero. It’s also nitrogen-purged and rainproof. Inside are emerald-coated lenses and the same Mil-Dot reticle as the BugBuster, but with a more advanced, 36-color illumination system. This is controlled by the EZ-Tap interface, which consists of two buttons under a cover that is mounted on top of the eyepiece. It also has a memory function; you can adjust it to exactly what you need for a tricky shot, then restore the last setting used with a single click.

As you’d expect from its larger lens, the image is brighter than the Bug Buster, and its quality is just as good. Its zero is controlled by turrets with zero-reset and quarter-MOA clicks, while a third turret on the left allows for easy parallax adjustment. The zoom is controlled by an easily operated and clearly marked ring.

This AR-15 scope has an integral sunshade above the objective lens; it’s supplied with quick detach mounts and flip-up caps. Overall, it’s very hard to beat on value, giving you great performance in a quality package.


Best AR-15 Optics: Long Range

Long-range optics are for long-range hunting/shooting. These are great scopes to pair with a shorter range option when running a dual scope setup with your rifle. Overall, the selection is a little bit more limited because most people keep to the medium range with an AR-15 and save the long-range hunting for other rifles.

With that being said, any of the three AR-15 scopes below can turn your rifle into a longer range varmint hunting tactical beast. Let’s dive in.

If you prefer higher magnification than the Prostaff offers, consider this larger P-223 sight. At 14.1 inches overall and weighing 17.5 ounces, this AR-15 scope’s extra size and weight bring a lot of additional capability with it.

This scope has a rugged, waterproof, nitrogen-purged tube and O-ring seals, and the lenses have the same multi-layer coating. The reticle uses the BDC pattern, with a series of rings and hash marks below the central crosshairs to allow easy aiming off. As it’s in the P-233 series, these marks are calibrated to the trajectory of a .223 round, which makes things even easier. Like the other Nikon BDC scopes, it’s compatible with their Spot On app, which lets you enter your bullet weight and muzzle velocity to get a customized aim point/range table.

Optically, the BDC 600 is more than adequate. The sight picture is free from distortion, and while the brightness fades slightly at higher magnifications, anything up to 5x is still perfect for twilight hunting. The zoom is controlled by the usual ring in front of the eyepiece, and a large stud makes it easy to rotate even with gloves on. You zero the weapon with large clicky turrets that feature Nikon’s Zero-Reset system; you can adjust the point of aim for a tricky shot, then simply lift the spring-loaded caps to quickly return to your normal zero. Overall, this very capable AR-15 scope lets you fully exploit your AR’s range.

Want more magnification? This scope has exactly the same construction and features as Bushnell’s 3-9×40, but extends the zoom upwards to 4.5×18. It’s aimed at hunters who make the most of their shots at longer range, where the high maximum power lets you place your bullets with extreme precision if you have a stable enough fire position.

Inevitably there’s a price to pay for its light-gathering power; anything above about 8x magnification is for full daylight only, as the 40mm objective lens will struggle in lower light conditions. At low power, it’s just as bright as the 3-9×40 though, so you can keep shooting as the light fades—you just won’t be able to use the full zoom range. It’s a more expensive optic, but if you do most of your hunting over open ground, this AR-15 scope makes a lot of sense.

  • Rapid-Z Varmint ballistic reticle provides numbered holdover...
  • Sleek, compact tube design compared to other 25x scopes
  • New 5-Year No Fault Policy + Limited Lifetime Warranty

What we like: Zeiss quality, warranty.
What we don’t: Cost.
Who it’s for: Intermediate to advanced.

Here’s where the old saying “go big or go home” comes into play. There are plenty of people that will say a 50mm objective is too big for an AR-15. Then there are plenty of people that will tell you that the 50mm objective allows the perfect amount of light in to see hogs at dusk during hog season. It’ll be up to you to figure out which camp you fall into. The bottom line is this: the HD5 can be used on multiple rifles and has multiple applications at longer distances.

The HD5 is much slimmer than the other best AR-15 optics, with a 25x maximum power and 50mm objective lens. Again, the name of the game is pairing. You won’t use this scope at close quarters, ever. But if you have a decent red dot scope already in your arsenal, Carl Zeiss scopes are some of the absolute best scopes in the business. The HD5 is the perfect pairing for long-distance coyote or any other varmint hunting expedition.
