How to Buy the Best Scopes for AR-10

How to Buy the Best Scopes for AR 10

While there are many factors that will determine your success as a AR-10 hunter or target shooter, your choice of scope is one of the principal ones. But, the good news is that you can still get a good scope even if you are not an expert or pro shooter.

Although there is also a lot of jargon and technical terms involved when shopping for rifle scopes, keeping the following important factors in mind when shopping will allow you to get a model that will give you great service and performance.

1. Optical Performance

While the AR-10 can still offer decent performance for both short and long range shooting, it is best suited for fast intermediate shooting. And so the scope that you buy needs to provide the optical performance for this.

First, it should be able to withstand the recoil that comes with fast intermediate shooting. Also, it should not be too bulky or heavy to ensure it does not put too much weight to your gun.

For the optics, you need lenses that are able to ensure maximum transmission of light (at least 90%), and this means they should not only have a large objective diameter but also multiple layers of coatings.

2. Magnification

Whether you are looking for the best tactical scope for AR-10 or are a hunter looking for something to improve your accuracy, magnification power will always matter.

While it is true the optimal magnification for you is subjective, the range that you are shooting from and what you intend to use the scope for will have an effect on the right magnification for you.

If you intend to shoot from long range you need a scope with a magnification power of at least 9x. For medium range shooting at least 5x should be okay while 2x can work for very close ranges.

Also, note that you need to choose between scopes with fixed and variable magnification power. However, the variable is always the best choice as it means the scope will be ideal for a variety of situations.

3. Reticle

As you shop for a scope for your AR-10, you also need to decide on the reticle pattern to go for. Just like the magnification, it will also depend on your shooting distances and conditions.

While different manufacturers will offer different reticle patterns and give them different names, the three most common options, are duplex, mil-dot, and BDC reticles.

Duplex reticles are ideal for shooters looking for a simple pattern for hunting and target shooting while mil-dot is best suited for precision shooting from 300 yards and BDC is your best bet where compensating for bullet drop is crucial.

4. Focal Plane

The focal plane is the position of the reticle within the telescopic sight when the scope is at different magnification settings, and it is also an important factor to consider.

Like with most other rifle scopes, you can get scopes for AR-10 with either first focal plane (FFP) or second focal plane (SFP).

The first focal plane scopes are the cheapest but the reticle size changes as you change the magnification setting, and so the sight picture is not consistent.

With the second focal plane scopes, the sight picture will be consistent at all magnification settings as the reticle size always remains the same, but these scopes can be a little pricier.

Different shooters seem to have varying preferences when it comes to the focal plane, and so it is mostly up to you decide which between the two works best for you.

5. Light Transmission

Light transmission defines the amount of light that the scope will allow to pass through and the higher it is the better.

It is typically measured in percentage for example 90% or 95%. Most manufacturers will indicate it on the scope description, and you should always aim to get the highest light transmission.

With at least a 90% light transmission, your scope will be able to gather enough light for a bright and clear enough sight picture even in low light conditions at dusk/dawn.

But, also note that things like the lens material and coatings and the diameter of the objective lens are key in determining the light transmission.

6. Price

When it comes to rifle scopes you always get what you pay for, and so in many instances the more you are willing to spend the better the scope quality you get.

However, it is also important to note that there are many budget models that are of decent quality and will still offer great performance.

Hence, when it comes to the scope price the right idea is to come up with a budget by deciding on whether you are looking for a good under $50 model or are willing to spend hundreds of dollars to get something more feature rich.


With the right information in mind, finding the best scope for AR-10 rifles should be a quick and easy task despite the fact that there are lots of models to choose from in the market.

And while there are still other things that you need to consider such as the ease of mounting and adjusting the scope and the eye relief you get, you should still be okay even if you just take the 6 points above into account when shopping.

For those that are wondering where to start their search, our top 7 scopes for AR-10 reviews are a good starting point. The chances are you will not even need to look further as all the scopes are top notch quality and will work well for both beginners and pros.
