However, there are hundreds of optics and scopes on the market with varying capabilities and features. It can be confusing to select the best one for your rifle.

So, what are the things to look for when buying AR 15 scopes?

Buying AR 15 Scopes? Here are Factors to Consider

There are several things that go into manufacturing a good scope. As a consumer, it is very important that you get hold of these factors so that you make an informed decision upon purchase. Here are some main aspects that you have to look into:

1. Type of Scope

First things first, you should know the different types of AR 15 scopes.

  • Rifle scopes: These scopes can either have variable or fixed magnification.
  • Holographic sights: These scopes have their reticles internally projected onto the targets using lasers.
  • Reflex: Also known as the Red Dot Sight, this is probably the most common AR-15 scope you will come across. It comes with objective lenses and the reticle is projected a point behind the lens which is reflected toward the eye.

2. Your Preference and Budget

As a rule of thumb, buy a scope that you are comfortable with. Read and research about different scopes and get to know the ones that meet your preferences. With these scopes in mind, you can filter out the ones that you can’t afford. This should give you a linear approach to the best scope.

3. Reticle

A good scope should have a good reticle. A reticle helps the shooter aim more accurately and easily.

Some scopes may have high-end reticles with so many features that may distract you from focusing on the shot. So ensure to choose an AR-15 scope with a good, clear, and simple reticle, especially if you are using it for practice or hunting. You wouldn’t want a lot of distractions, would you?

4. Adjustable Knobs

A good AR-15 scope should have an easily adjustable knob. The turret should be well-adjusted to easily zero in on the target. The knob should also have an ideal size for easy adjustment – not too long and not too short.  

5. Optics

Frankly speaking, a good optic is the biggest difference between a great and an awful scope. For best performance, the optic should have good quality and work well even under low light conditions. Therefore, ensure you go for optics with multi-coating features and produce HD images.

6. Magnification

A scope’s magnification power will determine how far you will see. If you take long shots most of the time, it’ll be a good idea to go for a scope will excellent magnification. However, the more magnification power in a scope, the more expensive the scope.

7. Nature of Your Targets

For tree stand hunting, you will want a scope that is geared for short range shooting and has a wide field of view.

If you shoot at moving targets, you should consider a red dot scope with an unlimited field of field. This will allow you to have the most viewable area and find your target quickly. Aiming at a moving target with a highly-magnified scope can be quite frustrating.

8. Sturdiness

If you are hunting, you are most probably going to face tough weather conditions and uneven terrain. Scopes are mainly designed for defensive and tactical use.

For that reason, a good scope should hold in all conditions. They should be built to withstand recoils, shocks, bumps, as well as the usual wear and tear. It is important that you get a system that can maintain a zero point during use.

It should also be fog-proof and waterproof for the best performance.

Before You Settle on an AR-15 Scope…

An AR-15’s range depends on a number of factors including ammunition, shooting skills, and the barrel length. Therefore, you do not need costly and high-power scopes for long-range shots. Typically, a long-range shot of an AR-15 tops at about 1000 yards. The ten AR 15 scopes mentioned above are effective enough to do this job excellently.
