Factors to Consider When Buying Best AR 15 Scope Under $300
When shopping for a good scope for AR15, there are a few things to keep in mind. One of the most important things to remember is that you can’t really compare a $300 scope to a $3,000 one.
What Type of Ammunition Are You Using?
That said, you can still find a quality scope at an affordable price. AR 15 optics recommendations will vary based on the caliber of ammunition you use.
Some scopes are specially designed for a given ammunition type, and their reticles show you where to aim in order to offset bullet drop.
How Much Magnification is Necessary?
You’ll also want to consider magnification. A scope with a high magnification power lets you zero in on a target, but remember that your field of view diminishes as you increase amplification. When choosing an AR scope for deer hunting or other longer-range application, try to choose a scope with a considerably adjustable range of magnification.
But if you are looking for squirrel hunting scope, check out those LR22 scopes reviews.
Thinking About Reticles
When it comes to selecting your scope, one of the most important considerations is the reticle type. Many scopes have crosshair reticles. However, you’ll need to choose between first focal plane and second focal plane designs.
A first focal plane reticle changes size with magnification, while a second focal plane one stays the same size. Some scopes also have illuminated reticles, which can make it much easier to shoot in lower-light conditions.

AR 15 Scope FAQ
When asking what is a good magnification scope for an AR 15, it can be helpful to review some commonly asked questions:
Generally, you only need very high-magnification scopes for long-range shooting. When hunting, you often need low to medium magnification in order to preserve your field of vision through the scope.
In some cases, the quality of your scope may be even more important than the quality of your rifle. The right scope lets you see your target clearly and aim correctly. Shooting accurately is important, and the right scope can help you do that even in non-ideal weather conditions.
Coated lenses usually improve the transmission of light and can increase contrast. This lets you easily focus in on your target. In many cases, coated lenses make it easier to see, even in low-light conditions.
