[Updated Post]

The AR-15 from Colt is the successor to the ArmaLite AR 15 (ArmaLite Rifle #15). In 1959 ArmaLite sold the design and naming rights to Colt who then produced a slightly modified version they dubbed the M-16 which first saw service in the jungles of Vietnam and in time became the U.S. Army’s standard issue rifle.

Today, Colt uses the designation AR 15 to denote their semi-automatic, civilian and law enforcement version of the weapon. They say “imitation is the sincerest form of flattery” and if that’s true the AR-15 is one of the most admired weapons in history as there are a slew of AR-15 clones on the market today produced by the likes of Bushmaster, Wilson, Baer, Rock River, Olympic Arms, and Panther.

Let’s Look at the Top 5 Best Scopes For AR 15.

The Best Scope

When it comes to determining the optimal scope for the AR-15 there are almost as many opinions as there are AR-15 owners. The difference of opinion, however, typically boils down to the fact that the AR-15 is one of the most versatile weapons ever produced. Shooters today use the AR-15 for a dizzying array of activities including:

  • Big Game Hunting
  • Home Defense
  • Competition Shooting
  • Plinking
  • Deer Hunting
  • Patrol Car Rifle
  • Fun and more…

As such, expecting one answer to the question “What is the best scope for my AR-15?” is like asking “What is the perfect Christmas present?” It depends on what you’re looking for.

Below we’re going to go through some of the factors that go into choosing a rifle scope and then select what we believe to be the 5 best AR-15 scopes on the market today.

What are Red and Green Dot Rifle Scopes?

If you’ve watched an action movie at any time in the past decade or so, chances are you’ve watched a scene where a red laser dot appears on the good or bad guy, indicating someone has them in their sights. This red dot scope that has become such a movie staple simply replaces the cross-hairs of the traditional scope with a spot of red laser light.

Being small lasers, however, such a scope needs a power source and most laser scopes utilize a small lithium battery that typically provides up to 6 hours of “on” time.

The newer, green dot scope is gaining more converts daily as they’re purported to be brighter and easier on the eye than standard red lasers. As with all things, though they are not without a downside and in this case, the “con” is that the green dot scope will drain your battery more quickly than a red dot scope and, as of this writing, they’re also more expensive. The green dot has also drawn some criticism for being harder to pick out than the more vibrant red.

Difference Between Variable and Long Range Scopes

A long range scope can provide extreme magnification (up to 40x or more) for targets far afield and tend to be fairly heavy and on the expensive side. If you plan to do long range target shooting or varmint hunting there’s no substitute for a high-quality long range scope.

It’s also not unheard of for shooters to use a 4x fixed scope which enables them to hone in on just about anything within 250 yards; although such a scope won’t be of any use if your target moves into close quarters.

Speaking of close quarters, if you work for law enforcement or are a more traditional hunter you may want a variable scope. This way if the buck is in your face, you’ll be able to get a clear shot and, if you miss, you can still scope it as it tracks away.

An oft-cited weakness of the variable is actually a human weakness and not the fault of the scope. That is that often times a shooter will forget to adjust the magnification as the target closes or pulls away.

What is Key Factor Between Budget & High-End Models?

The major difference between a high-end scope and a budget scope typically comes down to one thing: optics. Just as a more meticulously engineered camera lens will cost more than a discount lens, a scope with superior optics is going to set you back more than a scope with poor or middling optics.

In addition, while some less expensive scopes may provide more than adequate clarity and accuracy, they’ll tend to break down sooner and with more regularity than a well-engineered scope, simply because they’re engineered to less precise tolerances from lower quality materials. Some signs that your scope is on the fritz include:

  • Sudden change in click values.
  • A point of impact suddenly is different even though using same click inputs.
  • Uneven horizontal or vertical tracking.
  • Change in the amount of resistance in the scope when clicking.
  • Rattling sound from scope when moving the gun.
  • Reticle shifts noticeably from the center of the view.

There is no “ideal” point at which cost and quality find a perfect balance, but in general, scopes are like any other piece of precision technology in that the more you pay the higher the quality. To be sure though at the very high-end any advantages are likely to be appreciated only by a few scope connoisseurs.

Chances are if you go with a mid-priced scope you’ll probably get all the optics you need without having to pay for esoteric qualities that may never actually come into play while you’re shooting.
