Purpose of a Mount

Scope mounts all do a single purpose, they hold down a scope to its zero. That’s all it has to do, nothing else. If you start looking at multi-function scope mounts that have built in bubble levels, or 45 degree offset iron sights, or picatinny rails for attaching things to the mount, you’re getting away from the point of it and probably adding bulk and complexity for no reason.​

Look for way to slimline you weapon and you’ll find the scope mount is an excellent way for you to shed weight by using an aluminum mount, an ultralight mount, or simply a smaller ring and base combination. Regardless of how much the mount weighs, all it has to do is hold down the scope, it does it’s job, it’s good to go.​

Special Consideration for an Ar15​

The Ar15 is a light and fats carbine. The lineage from the battlefield gives the Ar15 special qualities like being more compact, more durable and rugged and ultimately in a different class of guns than most traditional hunting rifles.

Ar15’s almost always have back up iron sights, either built in or added in the way of flip up sights. If you plan on using these sights, you’ll need a quick detach scope mount. If the scope breaks or the battery dies, or gets dirty and you aren’t able to clean it, it’s going to prevent you from using your iron sights.

If your rifle is purely for hunting, and nothing else, you may not need back up iron sights, so you don’t need a quick detach mount for your scope. Plan ahead so you don’t over spend and take a realistic approach to how you’ll use your rifle.​

1. LaRue Tactical QD Cantilever Scope Mount​

LaRue Tactical QD Cantilever Scope Mount - LT104

LaRue is a god like company in the world of Ar15 accessories. A favorite of many enthusiasts this company makes many different models of mounts for people who are interested in extremely high quality gear from the USA that is going to last a long time.

Larue make products that really pay attention to the little thing. This mount is an ultralight quick detach mount that is only big enough to hold the scope’s zero. The entire mount has been slim lined to your field of vision clear and to keep weight to a minimum.

The quick detach cams lock onto the flat top of your receiver and has a few really nice features like oiling ports for the quick detach mechanisms, short levers with short throws to make the mount easy to remove and minimal tolerances for a repeatable zero.

The length of this mount makes it better for precision optics that are going to be put on and left for a while. If you see yourself removing your optic a lot, look for a small optic which will use a smaller mount. Overall if you need a high-quality scope mount for your Ar15 this is very hard to be in the quick detach category, which most rifles will need anyway.

Pros

  • Extremely high build quality
  • Quick detach

Cons

  • Expensive
  • no offset

​2. GG&G SOCOM II Quick Detach

GG&G SOCOM II Quick Detach Rifle Scope Mount

​GG&G is a good company, albeit much smaller than others, they make a great product. This is an excellent example, an ultralight weight aluminum optics mount made specifically for Ar15’s.

This at first glance is just a standard mount, but with many things; what’s not there is more important. The small levers are a plus, the light weight is a must, and the overall lack of “features” goes a long way for the mount just doing its job well, and nothing else.

The cantileverstyle of this scope mount allows you to adjust your scope to get it further away from your eye while keeping the mount on the upper receiver, perfect for maximum accuracy and for making sure you won’t lose your zero.

This is another one of the expensive class of mounts but the durability, craftsmanship and reliability of this mount can’t be over looked. It just does it’s job well while being totally unobtrusive and very high quality. If you’re going to buy one mount and expect it to last forever, this is the one to get.​

Pros

  • Extremely high build quality
  • Quick detach
  • Off set mounting

Cons

  • Expensive

​3. CCOP High Profile AR-ArmourTac

CCOP High Profile AR-ArmourTac Rifle Scope Mount Rings

This is a favorite online because it’s a good quality mount for cheap. In essence, this is the cheapest you can conceivably go for a mount of an Ar15. Lightweight carbines like Ar’s take a lot of abuse in the field and you can easily lose zero if your mount isn’t squared away.

This mount is the best of the cheap, so to speak. It is a basic mount designed to pop onto your flat top receiver and holds a scope, that’s it. The machining is accurate enough to get the job done, but the finish leaves a little to be desired.

The nice things about this mount is screws that hold the mount on and that hold the scope are all over built and the mount it’s self is beefy. Yes, it’s heavier than competing models but also much cheaper, so cheap in fact you could easily buy two or three of these things compared to a brand name price of another one.

If you’re on a budget, this may be your mount just be careful about hitting it and always double check your zero before a hunt or a match.

Pros

  • Very inexpensive

Cons

  • Low build quality
  • Low surface finish
  • Not from a major brand

​4. Vortex Cantilever Ring Mount

Vortex Cantilever Ring Mount for 30mm Tube

Say you want to really reach out and touch that far ridge with your rifle. Or say, you want a scope that is normally reserved for bolt guns, on your carbine. Well there’s no replacement for a 30mm tube! The bad news, putting a 30mm tube on an Ar15 is like a turbo charged mini-van, you run out of options.

This is one of the few options to put a 30mm scope on an Ar-15. It is from Vortex, a company known for their performance driven innovation. This is an all-aluminum constructed cantilever mount that has a full 3” of offset and is tall enough for a full co-witness.

The extra length of the co witness to allow for the proper amount of eye relief for the big scope that require critical eye relief. The absolute co-witness help you keep the reticle on track with the front sight to make sure all your sights match and the sight picture is simplified.

Rock solid, good to go. There’s not much to say about this scope mount. One of the best for precision Ar-15 setup sporting an optic that has a 30mm tube.​

Pros

  • 30mm scope mount
  • 3” offset mount
  • Extremely durable

Cons

  • Large mount

​5. Nikon P-Series Riflescope Picatinny Mount

Nikon P-Series Riflescope Picatinny Mount for 1 Inch Tube best scope mounts for ar 15

This is an interesting mount from Nikon that was designed to go hand in hand with their P-series of scopes made for the Ar-15 pattern rifle. This is a good option for guys running unconventional scope, or a varmint style rifle that has an optic with large turrets. The rings are built-in to the mount and the mounts are separate.

​You can move them as you need to for clearance working around turrets, a forward assist and a charging handle. The lightweight scope rings are all aluminum and no frills. All they do is get the job done simply and cheaply.

Although mainly a specialty item they can be used for any 1-inch tube scope if you prefer this type of separate ring combo.​

Pros

  • Inexpensive
  • Can be set up on an optic or receiver

Cons

  • Two separate pieces
  • A bit bulky

​Buying Tips for the Best Scope Mounts for AR 15

Don’t Buy for a Brand​

Brands used to mean a mark of quality for the consumer. Don’t fall into the trap buying a product specifically for a brand name. It’s not impressive to see you spent 3x times more than you needed to get the best scope mounts for AR 15. There’s no doubting the quality of some brands and the value they deliver but others are downright rip offs. Get the performance you need and nothing else, brands are overrated.

Loctite​

Super glue, super snot, Loctite, whatever you want to call it, the generic term being “Thread Locker” you need it on the screw that hold your scope to your rifle. Do not apply it to your QD levers, but for the ring screws, any mount screws, it is a requirement. The constant vibrations on the AR15 will cause it to literally rattle apart if you don’t take steps to insulate the vibrations.

Don’t Over Tighten​

People breaks more mounts by over tightening the levers on a quick detach scope mount than they ever will by thrashing on them in the field. It’s possible to mar the rails on your receiver, bend or break your mount, even damage your optic by cranking down those levers too tight! Same thing with screws holing dings or bases. Tighten them down until they no longer move and leave it! The Loctite, that you should’ve applied, will keep the screws from backing out.​

Check your Mount & Optic​

Every time you clean your rifle, make sure the mount is stable, oiled, and still rock solid. Many times, mounts will rust or corrode, compromising their job, and people won’t even notice because they’re so obsessed with the internals of the gun. The mount is a critical component of the gun, take care of it the same way you would a barrel or an action.

Aluminum vs Steel​

All the mount has to do is hold zero. For 99% of people aluminum is the better option because it’s not only lighter but resist corrosion and does better with constant vibrations. It also runs a much smaller risk of bending or marring your upper receiver’s rails. Overall if you have the choice, which with prices being so low, get an aluminum scope mount.

Don’t be Afraid to Return It​

When you go to dial in your optics set up it need to make sure it’s right. Especially on an Ar15 the height of an optic has to be right, either to clear back up iron sights, making snap shots at game or getting the extra .25moa of accuracy out of the gun, it needs to be right. Don’t be afraid to return a mount, as long as it’s undamaged, if it doesn’t fit right.

​The Verdict

If you made it into the field and intend on hitting the target and punching your tag, it’s going to take the right gear. The Ar15 mounts above are excellent to making sure your sweet little carbine can fully benefit from a magnified optic.

The best scope mount for Ar15 can make all the difference in the world to making sure you get on target, and stay on target without losing your zero of losing your optic. Get a sturdy mount that matches the performance of your optics and the job you have at hand and you’ll have nothing to worry about. Just make sure you get into the field and use it!​
