There are loads of rifle scopes on the Internet, ranging from Nikon to Bushnell as well as UTG to Vortex. There are well-known brands and not-so-well-known ones. If you want to go about searching for a scope that’s right for you, then it depends on your needs. What kind of shooting are you trying to accomplish?

However, to pick the right scope for it, know what you need it for. Do you shoot clay pigeons and real birds? How about big game? Do you wish to double as a sniper of sorts? You can even add personal preferences like reticle type and color into the mix.

In particular, the table below covers info comparing at least the ten best and highest-rated AR 15 scopes around on The comparison table gives you an idea of what to get, but it only covers half of the conversation. Its main purpose is to get you started in narrowing down the best rifle scope for your AR 15.

What Is an AR 15 Scope?

An AR 15 scope is a scope used for the AR 15 rifle, usually made with a telescopic lens that allows you to target your gun better at objects or games. The power of the impressive rifle is practically useless unless you have a scope that allows you to better target your targets with optimum precision. Even though finding the right scope for you is tricky, there are several factors you can use to better streamline your search.

For example, reticle size, glass quality, and material built will give you a better idea of a given scope’s quality as well as whether or not it’s a cost-effective investment in the most rugged or fragile of situations. Rifles copes, when compared to spotting scopes, are smaller and can easily be attached on your AR 15 to ensure your combat mobility at all times.

You can further improve your accuracy with the use of AR scopes, red dot laser sights and so forth. There are many different types of rifle scopes to choose from as you can easily see from the table above that place them under easy comparison in terms of popularity, price, and magnification. Most of them are either made by Nikon or Bushnell, if you’d notice.

If you don’t know which one to look for, then keep on reading, because this simple-to-follow AR 15 guide will further illuminate to you the many other different factors of consideration not covered by the featured table (which, admittedly, is more of a price and cost-effectiveness comparison chart than anything else).

The Hallmarks of a Good AR 15 Scope

A good scope for AR 15 should be able to magnify the target to your eye on the same optic plane as the image you’re viewing. These scopes magnify images by bending light rays through multiple lenses found within the scope. It’s the laws of physics in action. Lower-powered scopes have smaller lenses than their high-powered counterparts.

If you’ve ever used open sights, then you’re aware that you have to worry about several things simultaneously. Is the rear and front blade properly aligned with each other for both windage and elevation? However, even if they’re lined up, if the target is further away from your eye than the sights are, it can still end up out of focus.

Then, if you focus on the target instead, the sites might go out of focus on you. It’s a delicate balancing act to shoot reliably with open sites, like spinning ceramic plates while riding a unicycle. With a scope, all these problems tend to disappear, especially the best AR 15 scopes around. You get to align the center reference point and focus at your target without going out of focus.

In short, you have more control of where you want your bullet to hit as long as your scope is “sighted in” and whatnot. Acquire target, pull the trigger. That’s all you need to know. A great rifle scope that you can depend on is able to make targeting more precise through the benefit of lens magnification, as explained above.

However, not all scopes are created equal. Some scopes are more precise at making humane kills while shooting the bull’s eye or hunting down game than others in accordance to their price and magnification capabilities.

How to Choose the Best AR 15 Scope

When shopping for the best AR 15 scope, keep in mind that that all of them have reticle like crosshairs, a post, a dot, or similar markings that reference the center of field when looking through them. They also feature the following:

  • Magnification: Magnification makes it easier to see targets and make precise shots since you’re able to precisely see the target’s image magnified. This is even more the case with a laser point targeting system. There are two types: Fixed and variable. Fixed has constant magnification, variable is more preferable because it has more range and it’s more adjustable.
  • Reticle: The reticle (also known as crosshairs) allows you to hit a target accurately that’s been magnified by your scope. It’s commonly called as crosshairs because it comes in the form of a cross in the middle of your scope. It has many variants. Some come in duplex form (for camouflage operations), others come in dot form (for distant contact or sniper operations). Every type is good depending on the circumstances.
  • ParallaxThis is a hard-to-explain, technical feature that advanced gun users must know. A scope with more than 10x magnification makes the reticle come off the middle or becomes off-center without even moving your scope. Because of this parallax effect, your more than 10x lens should have adjustable objective lenses to counteract this flaw in long-distance scoping.
  • Eye Relief: Having a handle that’s ergonomic promotes hand relief that avoids carpal tunnel syndrome. In turn, a scope should have a good distance between it and the scope itself while still giving out a full image (since recoil could give you black eye if your eye is too close to the lens).
  • MOA or Minute of AngleFor example, a one-fourth MOA scope means that the bullet lands one-fourth inches from the specified bull’s eye of the scope’s crosshairs or reticle. It’s how precise your bullet landings are. This is an essential scope attribute for beginners to know about as well.
