What To Look When Buying A Best Scopes for AR 10

When you enter into a gun store, you will probably be greeted by a plethora of gun sights and scopes from different manufacturers. Pinpointing the best from the wide array of scopes you are presented with can be difficult. However, when you know what to look for, the process of identifying best scope for ar10 becomes easier.

Below are some of the factors I consider when I go out shopping for ar10 optics.

Optical Performance

AR 10 rifles 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 best scope for AR 10 rifles will be one with a magnification of up to 20X.

When you are deer hunting with your AR 10 scopes, 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 24 X or less.


magnification of scope

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

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

This is because the bigger the objective lens, the bulkier the scope. And when you are using an 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. Most budget AR optics are crafted from aluminum, which is a high-grade material that is as tough as it is durable. More expensive scopes are crafted from the same high-grade aluminum used in the making of airplanes.

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 rifle scope is whether it is a front or second focal plane scope. In the simplest of terms, the reticle size of a front focal plane scope changes when you either zoom in or out.

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

  1. 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.
  2. 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
  3. 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 and AR lower Receiver some of the bipods which are best bipod for Ar 15 also great for ar 10 too.

Nikon M-308 4-16x42mm Riflescope Review


If you are looking for a great ar 10 scope or  a best scope for 308 ar, then the Nikon M-308 16X42 mm is one rifle scope you should not pass out on. Designed for fast shooting and fast handling, this Nikon optic has what it takes to become your AR 10 scope of choice.

Objective Lens

Measuring 14 inches and weighing 5 ounces, this rather hefty scope is fitted with a large 42 mm objective lens. Thus, with this scope mounted onto your AR 10, you will have no problems taking down a wild hog in low light.​


While I am not a big fan of BDC reticles, frankly speaking, I find them a tad difficult to use, I must admit the BDC reticle on the M-308 is refreshingly easy to use. The reticle proved itself handy especially when firing an ar 10 in automatic mode.​


The AR 10 is no push-over and thus requires a scope that is sturdy enough. Fortunately, the Nikon M-308 is not only sturdy enough, but it is also shockproof. And it gets better; the scope is also weather resistant.​

VORTEX Optics Viper 6.5-20x50 PA Riflescope Review


Proceeding in at number 2 on my list of best scopes for ar10 is the VORTEX Optics Viper 6.5X-20X 50 PA riflescope.

Weighing 2 pounds, this scope shrugs off recoil and has a weather resistant 30 mm tube. Indeed to say, that this Vortex scope is very well made is understating things.

Optical performance

The 50 mm extra-low dispersion glass objective lens with an XR coating is responsible for the scope’s brilliant light transmission and crisp, clear images. The objective lens is paired with an eyepiece lens with a 6.5X to 20X magnification, for excellent long range shooting.

Ease of use

To make this scope as easy to use as is humanly possible, Vortex offers this scope with some fantastic additions, one of which is the MAG-Bar. The latter allows you to quickly and effortlessly change the magnification.


There are not many AR 10 optics that can claim to be better than this Vortex Optics Viper, and for good reasons. From its large objective lens to its multi-coated optics, this AR 10 optic is an absolute delight to use.

Trijicon VCOG 1-6x24 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 multicoated optics on this scope and the 24 mm objective lens have a terrific light transmission. Also, the images appear bright and super crisp.


Powered by a standard AA battery, the red illuminated reticle worked very well and proved to be a useful feature for targeting targets in low visibility. Also, the reticle has been tested and proven on the battlefield and is one of the best features of this scope.

Final words

Of course, there is a lot I can say about this scope, but in the interest of time, let me say that I was thoroughly impressed by this riflescope. Thus, despite its hefty price tag, there is a reason why this Trijicon is the preferred scope of choice for the army, and I dare say it is the best scope for ar 10.

Leupold Mark 4 LR/T 6.5-20x50mm (30mm) M1 Mil Dot Review


The Leupold Mark 4 LR/T 6.5-20X 50 mm scope is designed to help you hit long range targets with precision. But does it really live up to its name?

Well, I got to test this Leupold AR 10 scope, and I was honestly impressed.

Weight and Size

This Leupold model is not your average AR 308 scope as it weighs 22 ounces, almost double the weight of other scopes out there. Due to its weight, you will definitely feel the effects of fitting this scope onto your rifle.

Apart from being somewhat overweight, this scope is also quite long measuring 14.5 inches.


What this scope lacks in compactness, it more than makes up for in its magnification. With a minimum magnification of 6.5X and a maximum magnification of 20X, this scope is capable of spotting targets for 600 yards. In regards to magnification, this is the best ar10 scope on this list.


To summarize, the Leupold Mark 4 LR/T offers great value for your money. Therefore, do not be discouraged by its bulkiness as this scope has everything you require to make precise and accurate shots from long range. This rifle scope is one of the best leupold scope for ar 10.

Aimpoint M4 2 Minute of Angle Sight Review


The Aimpoint M4, 2 Minute of Angle sight, is marketed as a high-end Aimpoint red dot sight. This means it comes with a wide array of premium features.

But before we get 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.


Though it is a red dot sight, this Aimpoint qualifies to be one of the best scopes for 308 rifles. One of the amazing things about this sight is that it can be used with all night vision devices. Additionally, this sight has been tested and proven by the US Army.

Nikon Prostaff 3-9x40 Riflescope Review


The Nikon Prostaff 3-9X40 scope is arguably the best budget ar scope on this list.

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 rifle scope 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.

Zero-reset turret

To make hunting less complicated, the Prostaff is equipped with a zero-reset turret. This turret makes it easy to make adjustments when you are out in the fields. The adjustment is spring loaded and makes it easy for you to on the scope’s zero.
