Factors to Consider when Choosing the Best AR-15 Scope under 300


This is the first thing you should take into consideration. With the right scope magnification, you will be able to push your AR-15 to its full potential and be able to shoot accurately, even at extended ranges.

A variable power scope with a maximum magnification of 10x or less will be ideal. It will offer the perfect balance of good optical power and a wide field of view.


The best AR-15 scope under 300 is solid and built well to handle the recoil this rifle emits. A durable scope will also handle the hard knocks that come with hunting or shooting and ensure that it offers many years of field use.

Lens Coatings

Lens coatings in scope are very important. Without them, your scope will generate dark and dull image views and render your shooting impossible.

As you go through the plethora of scopes available on the market, ensure that you pick a model with fully-coated or multi-coated lenses. The coatings will enhance light transmission and yield bright, vivid, and detailed image views.

Eye Relief

The other important thing to consider is eye relief. With the AR-15 being a heavy-recoiling rifle, ensure you get a scope that offers ample eye relief of more than 3.5 inches. This will keep your eye safe from the fierce recoil the rifle generates.


Irrespective of the activity you propose to use the scope for, ensure that it has a weatherproof construction. It should be waterproof, dustproof, and fog-resistant to be operable in all weather conditions.
