The Best AR 10 Scope Contenders

Here’s the list of the best scopes for the AR 10 in case you don’t want to go through the reviews below:

What Are the Basics of a Rifle Scope for the AR 10?

While looking for scopes for your AR 10 rifle, you’ll find various variation aspects and basic points at which these scoops differ. To find the ideal one for your needs, you should know about the basics including how to adjust a rifle scope for the AR 10.

Here are some of the fundamental points that’ll help you pinpoint your perfect fit.


Ideally, riflescope ranges are classified into short-range, medium-range, and long-range. The short or close range is usually at about less than 200 yards.

This close range is ideal for hunting. A lot of hunters use short-range AR 10 scopes to hunt down small game like hare, fowl, and coyotes.

The medium-range scopes are the ones that you use to aim targets at a distance of about 200 to 400 yards. The range is a favorite for hunters. However, it’s only reserved for targets with larger bodies, such as deer, elk, etc.

Anything higher than 400 yards and up to 1,200 or even more requires a long-range riflescope. This is usually ideal for the most seasoned hunters, competitive long-distance target shooters, or those who are looking for a real challenge.

An AR 10 has a shooting range that tops at about 800 to 1,000 yards. However, it’s also commonly used for medium-range shots of 500 yards as it’s the sweet spot of the rifle range.

This means that based on the scope you’re using, you can shoot all three ranges with your AR 10 rifle.

Long Range Shooting

Check out our reviews of the top-rated scopes for long-distance shooting!

Glass Quality

The glass quality has a lot to do with the clarity of the scope and eliminating the distortion effects of the scope edge at long distances.

Ideally, you should look for coated glass that resists fogging. Also, the tube should be nitrogen or argon purged with tight sealing around the O rings.

This prevents the moisture from leaking into the tube and forming glass droplets inside the scope.

Additionally, you should make sure that the scope has decent shock resistance, which helps in keeping the reticle stable with the intense recoil of the AR10.

Light Transmission

The light transmission is controlled by the objective lens and the tube diameter. The wider the lens, the more light it takes it. Similarly, the larger the tube the more light can transition through it to your eye to paint a sight image.

This allows you to see clearly even in less-than-perfect light conditions (Best Low Light Rifle Scopes Reviews), which is why light transmission is essential for anyone who uses their AR 10 in the woods.

The Field of View

The field of view refers to the area (in feet) that you can see through the scope at a distance of 100 yards. The larger the field of view, the more you’ll be able to see at higher zooming power.

Elevation and Windage

The knobs on a scope are used to adjust elevation and windage. Windage determines how far a bullet can hit to the left or right of the center point. The elevation is the same for the vertical axis of the bullet.

What Magnification Do You Need for the Typical Use of a Rifle Scope for the AR 10?

Magnification is one of the most important features of a rifle scope in general. With a long-range rifle like a AR 10, the magnification powers become even more critical if you want to make the most out of your gun.

Ideally, an AR 10 would let you hit targets precisely within a distance under 200 yards without a scope. However, adding the right scope can help you hit targets at about 1,000 yards and even more.

The magnification of the scope is measured in “powers”. For instance, a 5x scope means that your target will appear 5 times closer than its actual position. Check here how distance and magnification are working!

Since most AR 10 scopes are classified according to their magnification abilities, let’s have a brief overview of these classes, so you can determine the ideal one for you.

Magnification for Short-Range Scopes

Using AR 10 with a small range scope would be quite an overkill, as you can already hit these targets without a scope.

However, if your target is ultra-small or requires extra precision, such as hunting with a dog, you might need them.

Short-range AR scopes are those that have a magnifying power of 1x to 4x or 5x. They’re the most affordable ones and are good enough for targets under 300 yards max.

In such a close range, many hunters either shoot without a scope or use a red dot sight with a magnifier.

Magnification for Medium-Range Scopes

The medium-range AR 10 scopes shoot targets between 300 to 500 yards, which is where the sweet spot of a AR 10 lies. That’s why they are the most commonly used scopes for AR 10s.

These scopes have a magnification power range of about 5x to 12x. They are usually good for hunting large game easily.

They vary in price significantly according to the quality of their glass and reticle details. Some of them can even be more expensive than long-range scopes. Yet, there are many affordable options as well.

Magnification for Long-Range Scopes

A long-range AR 10 scope usually hunts at a distance that starts from 500 yards and surpasses 1,000 yards. That’s why they need a magnification range of 12x and up to 25x.

This is the range where a lot of people have it wrong about the AR 10. 1000+ yards is a range where AR 10s show their true capabilities.

However, a lot of hunters buy scopes with exaggerated magnification power without ever shooting a target within that distance.

It’s ideal for sharpshooting and sniper contests, expert target shooting, and hunting at great distances. Keep in mind that some of these scopes can set you back a few thousand bucks!

Magnification Adjustment

The magnification power of any scope for AR10 is determined from its name. On the market, fixed and variable scopes are both available.

However, unless you always hit the same target within the same distance, a variable scope is the wiser investment to make.

What Are the Best Scopes for AR 10?

As you can see, finding the best scopes for AR 10 depends on many factors that you need to consider carefully. However, even if you know what you’re looking for, there are tons of options out there to choose from.

To save you the time and hassle of checking every single one of them yourself, we’ve scoured the market to find the best options in every category. Let’s have a brief overview of each one of these scopes and see what it has got to offer.

Primary Arms SLX 3-18x50mm – Best Short to Medium Range

We are kicking off the list with one of the most popular scopes for short-range and medium-range shooting. Primary Arms is a reputable brand that has a large arsenal of rifle accessories.

Primary Arms SLX 3-18x50mm FFP Rifle Scope

Their products are characterized by their excellent overall quality as well as affordability, and the Primary Arms SLX 3-18x50mm scope is worthy of living up to the name of Primary Arms quality.

The reticle is also illuminated in the middle portion with a bright red color. However, you can adjust the brightness of the illuminated reticle up to 6 different levels to suit your needs.

The illumination is powered by the widely available CR2032 lithium coin battery. Luckily, the scope comes with one that is included in the package!

The 50 mm objective lens diameter is excellent for letting a lot of light in, which helps you see clearly in obstructed light settings.

The scope has a wide-range eye relief of 3.9 inches to 3.5 inches. This helps you to adjust the AR scope to your vision, compensating for any vision problems.

The scope has a wide field of view that extends up to 36.7 feet at 3x magnification of 100 yards and 6.10 feet at 18x magnification at 100 yards.

The lenses are multi-coated for fog-resistance and have a great waterproof rating of IP67. This means that it can last up to 30 minutes under 1-meter deep water.

The turret adjustment on this scope is highly improved. It has a tactical and audible click at 0.1 mm variation. Using the turrets you can adjust multiple settings of the scope.

This one is the Vortex Optics Strike Eagle 5-25×56 riflescope, which is an excellent option if you’re considering a long-range riflescope with high-end features yet a relatively affordable price.

The scope has an extremely wide range of magnification power that spans from 5x to 25x. This means that this scope has one of the highest magnification ranges in its category.

The clarity of the glass is also an awesome feature in this scope. You’ll be able to get a crisp scope image with no distortions throughout its range of magnification.

However, in the highest magnifications settings of 24x and 25x, you might notice some slight distortions around the edge of the view lens.

The reticle of the scope is on the first focal plane, which allows its reticle to adjust to the distance you’re using. In other words, the reticle will become larger as you zoom in and smaller as you zoom out and grow or shrink proportionally to your target. This can help you fine-tune your shot at maximum distances and is the preferred option for long-range target shooters.

You will also be able to utilize the bullet drop compensation on the BDC reticle because it’ll stay the same on different levels of magnification.

Similar to the Primary Arms SLX, the Vortex Strike Eagle also features an illuminated reticle. You can adjust its brightness, so you can use it on both dark and light backgrounds comfortably.

The scope also has 5 holdover dots on its BDC reticle, which allows you to use it precisely with fast wind and elevation holdovers. This AR 10 scope allows adjusting windage by 78 MOA and elevation by 110 MOA.

This takes us to the next point, which is the turret adjustments. This scope comes with RevStop Zero System that allows you to modify the scope and set its zeros comfortably.

It also has a tactical locking feature to prevent accidental change in your scope adjustments. All in all, this scope is an excellent addition to your rifle if you’re all about shooting long-range targets precisely without costing you an arm and a leg.

The UTG 4-16×44 scope has some outstanding features despite costing a fraction of what some other scopes might cost.

Trijicon 1-6×24 VCOG Riflescope – Best Short Range Scope for AR 10

The best-known optic from Trijicon is clearly the ACOG (Advanced Combat Optical Gunsight). The Trijicon 1-6×24 VCOG (Variable Combat Optical Gunsight) is a little less known yet formidable.

The VCOG is, in our opinion, the best short-range scope for the AR 10 for a variety of uses, including close-quarter engagements, tactical scenarios, as well as for hunting. It’s evident from the 1-6x magnification range that this scope is not made for long-range shooting. However, it’s a great optic for CQC engagements and medium-range shots.

Trijicon VCOG 1-6x24 Riflescope
Trijicon VCOG 1-6×24 Riflescope

Trijicon produced some of the most reliable and sturdy gun optics that you can lay your hands on. The 1-6×24 VCOG is no exception. It withstands even the heaviest recoil you can find, and the ultra-clear glass makes it a joy to use this scope.

The scope tube is built with high-quality aluminum. It’s shockproof and fogproof. Trijicon designed it to be waterproof to 66 feet! It’s built to military specifications and, therefore, nearly impossible to destroy.

You can get the optic with several different reticles. One of them is the illuminated red dot horseshoe variant that is calibrated for the .308 / 175 Grain. The holdover points are calibrated out to 600 yards for this specific caliber and load. That makes this reticle an excellent match for the AR 10.

The illuminated reticle makes it possible to acquire targets rapidly. The reticle is positioned on the first reticle, and therefore, the holdover points stay consistent whether you use a 1x or 6x magnification. The 1x lower magnification lets you target with both eyes open (Bindon Aiming Concept).

The illuminated reticle can be adjusted through 6 brightness settings for the red dot and horseshoe. You can expect around 700 hours of battery life at medium brightness level settings. The scope uses a standard AA battery which is conveniently accessible and easy to replace.

Elevation and windage can be adjusted within a 90 MOA range. The adjustment graduation is 1/4 MOA per click. The field of view at 100 yards ranges between 15.9 and 95 feet. The eye relief is fixed at 4 inches allowing the Trijicon 1-6×24 VCOG to deal with substantial recoil from the AR 10. Parallax on the VCOG is not adjustable.


  • First focus plane reticle with illumination
  • Excellent glass quality
  • Rapid and accurate target acquisition
  • Superb build quality and ruggedness


  • Expensive
