What to Consider Before Buying an AR 10 Scope For Hunting

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 an AR 10 becomes easier.

Below are some of the factors I consider when I go out shopping for the best AR-10 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 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 24 X or less.


magnification Of AR 10 Scopes

The magnification range of a 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 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 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. Now a Days most budget AR optics are crafted from aircraft grade aluminum, which is a high-grade material that is as tough as it is durable. More expensive best scope for ar 10 are also crafted from the 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.
mil dot reticle
bdc reticle
  • 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 the lower receiver which are also somewhat great to use with AR 10 and AR 15 Rifles for bettere shooting.

    Leupold VX-3i 3.5-10x40mm

    Leupold VX-3i 3.5-10x40mm Rifle scope



    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.

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

    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.

    The optics
    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 a decent eye relief and an 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.

    It comes with the fast focus eyepiece feature which is essential for aiming on the moving target.

    Paired with the 40 mm objective size lens, it does a great job of bringing more light to your eyes.

    The reticle
    One of the best things about this scope is that its reticle is on the second focal plane. This means that as you change the magnification, the scale of the reticle remains the same. This is a huge pro, especially if you are aiming at targets at long range distances.

    Turrets Adjustment
    Capped turrets remove the possibility of them being accidentally adjusted. The turrets also allow for re-indexing to zero after you have sighted your rifle. There is also a zero-reset option particularly good for shooters who prefer shooting at multiple distances.

    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.
