Features to Consider When Buying the Best Scope for AR 15

1. Type of Reticle

The reticle type of the best scope may vary depending on the design and brands. There are four main types of reticles;

i. Mil-Dot

It is similar to the BDC reticle, but it has a big circle as its focal plane instead of having a crosshair intersection. It is mostly used for complex reticles but is very effective.

ii. Duplex

It is the simplest reticle that gives the least obstructed view. You will be able to see the subjects well because the crosshairs narrow down the closer you get to your target.

iii. BDC(Bullet Drop Compensation)

This one has basic marks which align to a specified range. It is a really nice one since you are able to alter the range while on the fly rather than sighting it in a specific range.

iv. Illuminated

It lights up, glows, and there are different control settings for customization.

Most people like the illuminated reticles because they have an excellent light transmission, even in low light. There are also options like the red, green-dot, or triplex reticle. A red dot scope tends to popular because of ease of use.

Magnification is one of the critical features that shouldn't be ignored if you're hoping to find the best scope for AR 15, especially when using it as a tactical rifle scope. With this, you can increase the image size and be able to aim even at long distances. It indicates how powerful scope is.

It comes in two number ratings that show the level and the diameter of the lens. The AR-15 rifle scopes may come with an additional number. For example, 3-9 x 32, which simply means it can magnify from 3 times to 9 times in the 32 diameter range. This is known as the variable zoom scopes. Fixed zoom magnification will only offer a specific level of magnification.

A larger objective lens means more a clearer and crisper sight picture. It would be best if you chose between the fixed and variable magnification scopes.

6. Weight and Size of the Scope

The best AR 15 scope is one that will match your needs and use. If you're planning on using it for short or mid-range shots, then the compact scope will be best. When looking for a long-range scope that can magnify up to 100 yards, the scope might have a weight of up to two pounds. However, regardless of the size and weight of the scope, ensure that it fits perfectly in your AR-15 flat-top platform.

7. Scope's Durability
