Things to keep in mind when selecting an AR-10 is to check its barrel and barrel nut, optics-ready upper receiver, objective lens and gas block for starters. Nevertheless, there’s plenty of horsepower in these guns and they can be harnessed and used better with the addition of a magnified optic. However, if you are looking for other battle rifles beyond the AR-10, please read on to know the best AR-10 for hunting and more.

Main Things To Consider

The AR-10 is an outstanding all-around rifle platform for any shooter with a multitude of aftermarket parts, a modular design and accessories readily available, wanting similar features of an AR-15, but with a slightly longer reach.

Trigger

This is one of the most arguably important features to look for in a rifle meant for long-range accuracy is a high-quality trigger.

There are two main types of triggers:

  1. single-stage

  2. Two-stage

Single-stage triggers are common in entry-level AR-10s. So it’s easy to choose the best AR10 trigger of your choice.

Barrel

If long-range accuracy is important, another feature to consider is the barrel of the rifle.

The newer rifles come with great features like MAGPUL stock, flip up sights, and pistol grips for best AR10 barrels. There is also a great compensator to hide the flash and help reduce recoil. The barrels are chrome lined and the trigger is two stage.

There are three main barrel constructions:

  1. Chrome-Lined

  2. Stainless Steel

  3. Nitrided

Chrome-lined barrels are the current standard for the US military because they last longer and have a reduced chance of rust. However, due to the natural inconsistency that occurs when chrome-lining a barrel, this type is not a match-grade barrel or highly accurate. At one hundred yards while firing from a bench rest, a competent shooter can expect two-inch groupings. Stainless steel barrels are “match-grade” or extremely accurate, but they have a shorter lifespan than chrome-lined barrels. Over time, the accuracy will degrade. With a stainless steel barrel, a competent shooter should be able to make one-inch groupings at one hundred yards. Nitrided steel barrels are a happy medium between chrome-lined and stainless steel barrels.

Why a Scope?​

Scope do a lot for a shooter, mainly they allow to see targets at a distance better and simplify the aiming process by replacing two movable sights with one. Let's not forget that one of the biggest keys to long-range shooting is optics. A scope usually meaning a magnified optic is a way to incorporate a telescopic lens to let you see target up to literally miles away.

It’s important to remember that magnified optics do not make you shoot better, they are an eye relief and lets you see better. This small difference accounts for a missed game every year. They do simplify the aiming process because you no longer have to align a front sight, rear sight, and a target.

All you need do is align the reticle with the target. You still have to deliver your fundamentals though, otherwise, you’re going to miss the shot, the most expensive scope in the world won’t help the inexperienced or untrained shooter hit the target. We will review below best scopes for AR-10.

What to Look For?

Ar 10 rifles are a special breed. They’re trying to be like Ar-15s but they’re chambered in a full sized cartridge and weight too much to be a carbine. They don’t do anything well except put big rounds down range in a hurry. Any light and fast carbine will benefit from scope like these 5 best scope for sks rifle.

Try and capitalize on this and get a lightweight scope with a fast focus reticle and turrets to take advantage of the range potential of the .308 cartridge.

These qualities should be easy to look for except…

Buying a rifle scope today is hard. Despite the internet making every option and all the information needed available, there’s still a mountain of decisions to overcome. There’s literally over 50 brands of scopes to choose from as well as dozens of other no-name Chinese import scopes available for pennies.​

For example, you can buy a crowd favorite - the Armalite AR-10. This original AR-10 by ArmaLite is a rifle for purists who prefer Eugene Stoner’s classic design but want a flat-top upper receiver. A twenty-inch stainless steel match-grade and free-floating barrel, precision two-stage trigger, and ArmaLite handguard ensure that this rifle is a tack driver right out of the box. The DD5 series is a modernized take on the AR-10 and features a cold hammer-forged free-floating barrel. It also has a KeyMod handguard, ambidextrous controls, Geissele two-stage trigger, and a top rail that runs from the charging handle almost all the way up to the flash suppressor.

But that’s not all! We’ve sifted through the market and based on reviews and professional experience have picked five of the best Ar 10 rifle scope money can buy.​ Here is our take on the best AR 10 rifle:

Even if the battery dies the fiber optic will illuminate the reticle. You won’t break it, and you don’t have to worry about the magnification because it’s fixed.

This is their idea to marry the best qualities a red dot and a magnified optic have to offer in one single package.

The FireDot reticle is a way to add a red dot to a magnified optic. The optic is limited to its 4x power range but the scope was designed from the ground up to be for an Ar pattern rifle.

The Trijicon ACOG is one of the most successful optic designs to ever be built. The evolution of that is to remedy one of its main features, or limitations depending on how you see it, the fixed magnification.

The VCOG is the Variable Combat Optical Gunsight and is just as tough but it combines a battery-operated reticle and 1-6x power scope. It still includes a one piece rugged mount, a BDC reticle good for 1000 yards, and is still bulky, heavy and bomb proof.

The main problem with this scope is the cost. The premium features and design costs a lot especially for the level of brightness and magnification you get.

The cost alone makes it prohibitive for most shooters but nonetheless, it might be one of the best ar10 scope recommendations that have ever been made.

Pros
  • Rugged as All Get-Out
  • Intuitive
  • Easy to Use Reticle
Cons
  • Expensive
  • Heavy

Rifle Scopes for Ar-10 Buying Tips

Quality is King

When you shop around for a rifle scope you’ll notice that they get expensive very quickly. Don’t buy a brand just because it’s a brand name. In some circumstances, a brand name is important for proprietary features and warranty but you can almost always get the same infield benefits for less with an off brand. Quality trumps brands, every time.

Coatings

Coatings on lenses are what make the light traveling through the scope clear. Some companies have proprietary coatings that filter colors and make the targets stand out better. Other companies use the cheapest coating things they can. Pay more for a fully multicoated lens with a good light transmission, otherwise, it’ll be dim at noon and unusable at dawn and dusk.

Dial it Down

More is not always better when it comes to magnification. Try and get in the habit of always dialing the magnification down to the lowest power whenever you stop shooting. This means once you’re done sighting in your rifle, dial down the magnification before you pack it up and head to the field. You never know when you might make a snapshot while hunting and you’ll regret it if you miss it because your magnification was up to high.

BDC Reticles

Make sure if you purchase a BDC reticle you know how to use it. They’re getting better than they use to be but they can be difficult to use under stress and aren’t very intuitive. Practice is the keyword and activity here, make sure you know how to use the reticle at all magnifications and ranges. The field is not the place to find out if it works or not!

Rings & Mounts

Make sure you leave room in the budget for quality rings and mounts. The Ar market is flooded with awesome products but you can never go wrong with a manufacturer’s in-house brand for rings and mounts, especially if you bought a quality scope. Quick detach mounts are nice, and sometimes necessary, but add weight, bulk, and cost.

Turrets & Dials

Turrets and dials have their place in the optics world but you should really look for low profile and easy to use dials and turrets. Huge turrets can be useful for precision rifles but for a lightweight carbine or hunting rifle they’re largely unnecessary and will hurt you in the field.

Warranties

The American optics industry is one of the best in the world and should you need any support for your product most any company will take care of you. Especially the giants like Leupold Bushnell, you’d be hard pressed to find any negative remarks about their customer service or warranty problems.

Final Review of the Best Scope for AR 10

The scope is highly technical, expensive, and hard to understand. They’re wizardry and cost makes them hard to experiment with. If you stick to a major brand and outfit yourself with one of the options here, you won’t be disappointed. By no means is this an exhaustive list, but you can certainly begin to understand what to look for by the offerings outlined here.

Even though iron sights come standard on most rifles and handguns, these sights have many benefits. But, if you’ve got a flat top Ar10 that’s begging for an optic, get to it! There’s no reason for people to be shooting iron sights these days with so many good options coming in at all budgets and styles on the market. Look for a quality scope, one designed to be the best scope for ar 10 carbine, and get into the field and use it!
