What You Need to Know When Buying AR 15 Scopes

Below are several factors to consider when purchasing a scope for your AR 15 rifle?

best ar 15 scope


The more you zoom the more the image distorts. Different scopes have been designed to reduce this distortion. What matters most is the needs you have from your rifle.

Once you know this, you will be able to know the best zoom for your scope. A hunter will need a greater zoom for his scope and on the other hand, a tactical shooter will consider less magnification and more clarity.

Focal Plane

This is simply what you see when looking through your lens. Focal planes are of two types; the front focal plane and the rear focal plan. The front focal plane is mainly used for tactical purposes while the rear focal plane is used in low light environments.


There are different styles of reticles depending on their uses, these are;

Duplex Reticle

They are the most basic and popular They offer a simple cross placed over the target which allows for easy target acquisition. It allows the shooter to decide on the range he/she needs.

BOO Reticle

Unlike the duplex long range, the BOO reticle shows typically 25-600 yards. This makes it more versatile especially in the tactical theater of the AR 15. Mostly used by tactical shooters and law enforcement.

Mildot Reticle

Features rings for different distances, this helps in covering the vertical distance of the scope. This comes in handy when shooting a moving target no matter the speed at which it is moving.

Minute of angle and MRAD

This is a mathematical equation that determines the exact distance of what an inch means in your scope. This is how it works, a circle is divided into 360 degrees, each degree is further divided into 60 minutes. This formula will help you account for ” leads” when shooting.


This is when the focal plane is not aligned. When looking at a target through the scope at about 100 yards, try glancing to a different part of the target and see if the image moves. If not then it means that your Parallax is not aligned, though many scopes have adjustments for this.


Over the recent years, hunters have been using rather power cartridges with their AR 15 rifle, just by using different barrels, bolts, and magazines. Therefore, knowing what the rifle will be used for, whether for hunting, long-range shooting or something else, is very important when looking for the best AR 15 scope.

Fortunately, all three of the AR 15 riflescopes reviewed above can be used in a myriad of different hunting and long-range shooting scenarios. All three of them are pretty dynamic, flexible and versatile, while their respective features make them quite accurate, precise and reliable.

For all those who have read this, one of the above three AR 15 riflescopes is sure to suit your particular hunting or shooting needs.
