Last update on 2023-05-03

Before the AR 15 came into the picture, its older brother the AR 10 was the gun of choice for many hunters, and it still is. The popularity of the AR 10 has been increased by the widespread use of the .308 Winchester cartridge which is the most used AR 10 round in the country.

To get the most out of your AR 10 and 308 Winchester cartridge you will need a scope that is of high quality and is functional.

And with the rifle scope market being flooded with all kinds of scopes from different manufacturers, finding the best AR 10 scopes is easier said than done.

But do not be worried for to help you is what I am here for. Below I have reviewed 10 of my top-rated AR 10 scope suggestions.

Why Should You Trust My Reviews?

I have been involved in shooting for many years, and I know what it takes to get accurate shots, so you don’t miss your target.

As a result, I have been able to find the best scopes that will suit my audience’s needs depending on their shooting style.

All of the scopes that I review are products that I have personally used or tried to get a sense of what they’re like before posting them up here. And all of these reviews are written by me, with the goal of giving people a sense of what they’ll be getting if they buy that product.

How I Tested Those Scopes?

I tested 35+ different scopes for AR 10 rifles and then narrowed it down to the top 10.

I tested the scopes by shooting at an inanimate target from various distances and seeing how they performed. I also checked to see any distortion or blurry images when being shot through these scopes. I also tried to see if there was any glare that would affect my ability to target.

I had the scopes set at a fixed distance, and I checked for eye relief, which is how close you have to be from your scope in order for it not to hurt your eyes or give you blurry images of what’s being shot through it.

I also checked to see how easy it was to switch from target to target with each scope.

Also, I have reviewed the best automated progressive reloading press of today’s market to help the shooters and hunters for the need of several hundred rounds every weekend.

What to Consider Before Buying an AR 10 Scope For Hunting

Almost everyone who owns a rifle wants to enhance the accuracy of their shooting. One way to do this is with the use of an optic or scope. There are many different scopes on the market, and it cannot be easy to decide which one best fits your needs and budget. I will walk through some questions you should ask yourself when purchasing a scope for your AR 10 Rifle so that you can make an informed decision about what type of scope is right for you!

Below are some of the factors I consider when I go out shopping for the best AR-10 optics.

Purpose of using AR 10

The most important thing is to consider the primary use of your rifle and which features work best with this type of shooting. For example, if you plan on using the rifle primarily for hunting, then a variable power scope may not be the best choice because it would require you to make adjustments every time you change distances from your target. However, if you’re looking for something more versatile like an all-purpose scope or if you’re starting in long-range shooting, then a variable power scope might be perfect for you!

Keep in Mind The Shooting Distance Of AR 10

You probably know AR 10 is that powerful and accurate that the military uses the modified AR 10 version for American snippers. And the good thing is you can easily shoot up to 200 yards without using sight, but you need to use a scope for medium to long-distance shooting.

So anything below 200 yards considers as short-range, while 200 – 400 yards is deemed medium-range and anything more than 400 yards is long-range.

Now I think you can figure out your shooting distance also if you prefer to shoot in the various distance, don’t worry I will explain that in the next paragraph.

Optical Performance

Please Don’t just buy seeing the numbers of the power because that doesn’t matter if you don’t know what magnification to choose.

If you prefer Close Range shooting ( Less Than 200 Yards)

First of All, AR 10 generally not for close-range shooting. But If you want to shoot at short-range, 200 yards or less, then a red dot sight is perfect because of the accuracy and clarity it has that can help you get more accurate shots. The magnification I would recommend for short-range about the power of 1X to 4X. You can check the review of Red Dot Sight Under $100 in case you prefer to red dot sight for close-range shooting.

If you prefer Mid Range shooting (200-400 yards)

If you shoot in between 200 to 400 yards, then a scope is the best choice because it has more magnification and allows you to see your target better. The magnification I would recommend for mid-range about the power of from 5X to 10X.

If you prefer Long Range shooting (400 yards or further)

You can use a long-range scope for shooting beyond 400 yards. And the magnification power you can choose from 10x to 25x. But remember having high magnification scope is not always the best.

That is because when shooting with high magnification, recoil can be a problem and lead to missed shots. So training and practice are vital if you want to hit your target from a longer distance.

AR 10 rifles are designed for fast intermediate shooting. Therefore, you will need to look for a scope that can withstand recoil and also one that is not too bulky. Additionally, being an intermediate rifle, the scope for AR 10 rifles will be one with a magnification range of up to 20X.

When you are deer hunting with your best AR 10 scope, you will find it difficult to make a shot with a 32X magnification. In this regard, for your AR 10, I recommend buying a scope with a maximum range of 25 X or less.



The magnification range of scope will determine its objective lens size. Low magnification is always accompanied by a small objective glass size of 40 mm or less.

On the flip side, a high magnification has to be paired with a wide objective of a 50 mm lens and over. For AR 10 scopes I recommend an objective lens of 40 mm.

This is because the bigger the objective size, the bulkier the scope. And when you are using a AR 10 for hunting, a large scope can set back the efficiency of your rifle.

The Body

As is stated earlier, the AR 10 rifle is designed for fast shooting. As such, it needs to be matched with a scope that can withstand its recoil. Therefore, it is important to consider a scope’s body or construction. Nowadays most budget AR optics are crafted from aircraft-grade aluminum, which is a high-grade material that is as tough as it is durable. The more expensive best scopes for ar 10 are also crafted from high-grade aircraft-grade aluminum.

Overall, the right scopes for ar 10 rifles need to be durable and very well made to withstand the recoil that comes with firing the AR 10 rifle.

Focal Plane

Focal Plane Another factor that I consider when buying a scope is whether it is a first focal plane riflescope or second focal plane scope. In the simplest of terms, the reticle size of a first focal plane scope changes when you either zoom in or out.

focal plane

Contrastingly, the size reticle of a second focal plane does not change and remains constant whether you zoom in or out. For my AR 10 rifle, I prefer and recommend using a scope with a front focal plane, especially for long range shooting.

Apart from the above discussed there are

Other Important Factors To Consider

  • The reticle is one of the things I consider most. Essentially, a reticle can either be a mil dot or a BDC. Personally, I prefer the mil dot; however, a BDC reticle can also come in handy in certain situations.




The reticle can also be illuminated. While this isn’t matter if you do most of your shooting during the day, an illuminated reticle will be useful for dawn hunting

The final factor I consider is how easy it is to mount the scope onto a rifle. Scopes come with different types of mounting rails. Thus it is important to choose a scope whose mounting rail is compatible with your rifle. Also, Consider a great bipod such as the and lower receiver which are also somewhat great to use with AR 10 and AR 15 Rifles for better shooting.

Best Tactical Scope For AR 10 308 Shtf: Vortex Optics Viper PST Gen II 5-25X50 First Focal Plane

The Vortex Optics Viper PST Gen II 5-25X50 First Focal Plane Riflescopes is a great scope for hunting and shooting. I have mounted this scope on my Aero M5E1 .308 rifle and want to share the experience with you.

I already said shooting anything beyond the 400 yards needs a medium to long-range rifle scope with magnification power up to 10x. I have tested this rifle in close to 1000 yards range, and it works well. The magnification remains clear and parallax-free up to 1000 yards during the sunny day.

This riflescope comes with EBR-2C (MOA) Reticle style, which was good for me as a tactical precision shooter because it provides me more accurate hold points. This reticle is designed especially for long-range shooting.

I have also tested the scope in low-light conditions, and it works well. The reticle is illuminated with bright colors, which makes my target visible. You can adjust the reticle with ten illumination settings.

During my test, I was impressed by the laser-etched turrets. You can quickly adjust the reticle for windage and bullet compensation without any hassle. These turrets produce crisp, tactical clicks with each turn. And zeroing the turrets is simple and quick.

The RZR zero stop feature is generally found in the Nightforce scope. It also has the RZR zero stop, which is very convenient for adjusting windage or elevation without counting clicks to return to your original setting, which is a great addition from vortex optics.

The 1080p glass clarity is very impressive. It offers the best images, and I can see everything clearly in it, even when aiming at targets for long-range shooting. The scope has Extra-low dispersion glass to provide that clarity because of its power and the 50mm objective lens to gather more light into a single point.

You will get a decent 3.4″ eye relief in this rifle scope, and the eye box is very forgiving. This is just enough to avoid any interference from the rifle stock. You won’t feel like your nose is smashed against the scope, and it’s not as if your head is tilted up to see through it.

The Vortex Optics Viper PST Gen II is waterproof, fog-proof thanks to its O-ring seals and argon gas fill. This is a really good thing because this will protect the scope in any weather condition you are in.

For more durability and ruggedness, it comes with an Armortek coating which ensures the lens will be protected and will not get any scratches.

One of the downsides of this scope is that the reticle does an odd job at the lowest magnification. The reticle crosshair is slightly thin at the lowest magnification, but the problem goes away when you increase the magnification. This is because the riflescope is the first focal plane which means that the reticle will change depending on the magnification.

The good thing is I also mounted the scope on my AR-15 M16 Model AeroMkII. I have used this rifle for a long time, and it is one of the best rifles that I’ve ever shot with. It’s very accurate, lightweight, well-balanced, and reliable. So Vortex Viper PST Gen II was no exception when compared to other scopes.

Review of Sightmark Wraith Digital Night Vision Riflescope

Sightmark is a company that specializes in night vision and thermal imaging technology. I was looking for the best digital rifle scope for AR 10 rifles and found Sightmark Wraith Digital Night Vision Riflescope to be one of them.

I mount this scope on my Daniel Defense DD-MV-22 rifle, and guess what? It is the perfect fit.

The price tag on this scope is just under $500, which is a bargain for such quality. It has a great 1920×1080 HD sensor that offers a crisp and clear picture full of detail.

The interface on the riflescope is easy to use, and it has functions such as 8x digital zoom in/out buttons, video recording buttons, and so on. It also comes with your choice of classic green night vision mode or black-and-white.

It comes with 10 reticle options that let you choose from various crosshair patterns, dots, and post to suit your shooting style. You can choose 9 different colors for reticles as well.

One of the best things I found in this rifle scope that it has 5 weapon profile presets. It was easy to zero in, and I found this scope to be an excellent choice for shooting at targets from 100 yards out-to-800 yards away.

Inside the box, you will get an 850nm IR flashlight; you can detect additional 200 yards of range by using that. Also, you will find an Objective lens cover, Picatinny mount, and instruction booklet.

This scope was easy to use and had excellent clarity even in the dark, which is a major plus for those hunting at night. My only complaint with this riflescope is that it doesn’t come with clear instructions on how to mount the light, so I had to guess and figure out how to do it myself.

No products found.
No products found.

If you want a budget range but value for money hunting scope from Vortex Optics that you can use for your AR-style rifle, Crossfire II is what you are looking for.

I have been using this scope as one of my go-to scopes for coyote hunting. I found it tight accurate up to 400 yards even at 9x magnification.

I mounted this scope on AR-10 (7.62×51), and the good thing is It holds zero as tight for me, and I am happy with the performance.

The Dead-Hold BDC reticle gives me many options to choose from when estimating range and holdover. Especially in areas where conditions can change dramatically over short distances, like fields with a dense cover on one side and open terrain on another.

The turrets are finger adjustable, and the MOA clicks are good for me because I can reset them to zero after sighting in at 100 yards.

It has a solid aluminum construction with a single-piece tube, and the best part is that it is nitrogen purged and o-ring sealed. Which means it is waterproof and fog proof.

Plus, the optics are fully multi-coated, so I don’t have to worry about light reflection or lens flare.

I recommend it to anyone looking for an affordable scope that does a good job up close – 300 yards or so.

Leupold VX-3i 3.5-10x40mm


If you hunt in mountainous regions, you will be conscious about how much weight you have pulling on your shoulder. A lightweight rifle scope is thus something you will want. Introducing the Leupold VX-3i. The latter is one of the most lightweight scopes on the market. But that’s not the only great thing about it.

The optics

The optics on this scope are impressive. The lenses are coated, and index-matched something that is exclusive to Leopold. What this means is that you get a bright and crystal clear picture quality. The edges of the lenses are blackened to minimize light diffusion so that you get more light hitting your eye. It is one of the best scopes for low light conditions. This scope is 100% waterproof and fog proof. And the more good thing is for its rubust construction it earn the title of the most shockproof riflescope for an AR 10.

FireDot ballistic reticle

When it comes to the reticle it is a firedot ballistic reticle with an illuminated red dot. You get additional aiming points out to 500 or 600 yards. The crosshairs are surrounded by a circle that helps improve target acquisitions.


With a simple turn of the power selector, you can switch between the minimum and maximum magnification range. And for making a distant shot, you have the ¼ MOA finger-click adjustments for adjusting windage and elevation.

Primary Arms SLx3.5 4-14x44mm FFP Rifle Scope


The Primary Arms SLx3.5 is marketed as being specifically designed for the .308 round. I thought I’d give it a go and see what it can do. For its price, it performs exceptionally well. I was a bit skeptical about the reticle being a mil-dot fan.

The reticle

So let’s start with what I think about the reticle. It is a First Focal Plane reticle. Though a bit more cluttered than a mil-dot reticle, it does what it is built to. It offers target leads for six target speeds all the way out to 600 yards. It also has a bullet drop compensation for long-range shots.

Optics Quality

Compared to some of the pricey models I have used, the optics on this one are ok. But when compared to similar products, the optical performance is exceptional. It has decent eye relief and excellent color reproduction.


The construction is also world-class. The entire scope is waterproof and its inside is sealed and nitrogen-filled purged, so you know its waterproof and fog proof. Also, it’s shockproof. The exposed tactical turrets turn smoothly. When it comes to mounting, it is compatible with most mounting rails.

Trijicon VCOG 1-6×24 Riflescope Review


I am a big fan of trying out new optics. So when a friend of mine who once served in Iraq introduced me to his Trijicon VCOG 1-6X24 riflescope, I could not wait to try it out.

Made entirely in the US, this Trijicon variable scope is quite impressive and has all the functionality and toughness that we have come to expect from Trijicon.


Given that this is a scope that has been used extensively by the army, I was curious to find out how its optics performs. And true to Trijicon’s standards, the fully multi coated optics on this scope and the 24 mm objective lens have a terrific light transmission. Also, the images appear bright and super crisp.

Aimpoint Comp M4 Sight Review


The Aimpoint comp M4, sight, is marketed as a high-end Aimpoint red dot sight. This means it comes with a wide array of premium features.

But before getting to the features, let’s consider its design first. The design of this sight is unique, to say the least. Measuring 6.8 by 4.5 by 3.5 inches, this scope is quite compact and weighs 9.3 ounces.

Red dot

With a reflective coating on its lens, the red dot of this sight appears super bright. Apart from being bright, the red dot reticle is also powered by a single AA battery. This battery is long lasting and is unlikely to die on you.


Shipped alongside my Aimpoint, the QRP2 was compatible with my .308 rifle. Also, included in the package was an integral mount, which eliminates the need for mounting rings. This mount is compatible with a wide array of rifles with either vertical or forward spacer.

However, do not let its budget status fool you as this is a scope capable going toe-toe with the big boys. With a beautiful matte black finish, the Prostaff is among the best budget AR optics and here is why.

Optical performance

The Nikon Prostaff 3-9X40 is a truly inexpensive rifle scope that does not compromise on optical performance. Therefore, do not expect the light transmission and image clarity of this scope to be similar to that of other budget scopes.

Indeed, this scope is fitted with multicoated optics that gives it its excellent light transmission and image clarity.

Magnification and objective lens

Its 3-9X magnification epitomizes the versatility of this scope. Paired with a 40 mm objective lens, the magnification is magnificent and offers an adequate field of view for open field hunting. The eye relief of this scope stands at 3.6 inches. This number means that this scope can be used in various landscapes.
