The reticle can be aligned to perfection since it has hand-turn adjustments. The reticle’s ballistic circles are see-through, which is ideal for long-range shooting, but at the same time, the crosshair can still be used as an aiming point during shorter-range shooting.

Compared to the other two AR-15 rifle scopes reviewed here, the CVLIFE Hunting Rifle Scope 2.5-10x40e is unique because it also happens to be equipped with a gunsight laser. That makes this riflescope even more accurate.

Bushnell Optics Drop Zone-223 Reticle Riflescope

The versatile Bushnell Optics Drop Zone-223 Reticle Riflescope is one of the most accurate, precise, and reliable AR 15 scopes available today. Like the Nikon Prostaff 3-9×40 Riflescope, all of its optics/lenses are fully multicoated.

Using rather low-scope rings may not be possible with this riflescope because of its erector cap assembly, which is present beneath it. Contact with the cap can be avoided by using rings that have a medium height.

In addition to all the above, this riflescope will prove to be quite long-lasting, considering that it also happens to be both rustproof and scratchproof.

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.

Magnification

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 for 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 plane. The front focal plane is mainly used for tactical purposes while the rear focal plane is used in low-light environments.

Reticles

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, and each degree is further divided into 60 minutes. This formula will help you account for ” leads” when shooting.

Parallax

This is when the focal plane is not aligned. When looking at a target through the scope at about 100 yards, try glancing at 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.

Conclusion

Over recent years, hunters have been using rather powerful cartridges with their AR-15 rifles, 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.
