A Definitive Guide To Finding The Best AR-10 Barrel

The purpose of the AR-10 platform is to get more power and long-range precision out of the AR platform. Who doesn’t want more power and precision? To capitalize on that power and precision, it makes sense to get the best AR 10 barrel you can find. The right barrel will allow you to maximize the benefits of using the larger 308 round in a semi-automatic AR-10 battle rifle.

Faxon Firearms’ high-quality, affordably priced AR10 barrels are all manufactured in the United States and ready for reliable and accurate long-range shooting.

They are made with the finest 4150 Chrome Moly Vanadium or 416R Stainless Steel and rifled for the best possible velocity and accuracy. Before we get into finding the best AR 10 barrel, let’s answer some of the most common questions about AR10 barrel selection.

AR-10 Barrel Length Considerations

There is more to consider about the barrel length than its effect on velocity and accuracy. For example, your barrel length will dictate your choice of accessories, such as handguards. Do you want something that just goes past the gas block or something that runs the full length out to the muzzle?

This can be important for aesthetic or practical reasons, such as ensuring that a suppressor or other muzzle device has enough clearance between the end of the muzzle and the handguard. In addition, a longer handguard provides more real estate for accessories like optics, sling mounts, and bipods. Finally, keep in mind that the length of the barrel will play a major part in the rifle’s overall weight, which is something to consider if this is a hunting setup.

What is the optimal barrel length for 308?

Barrels lengths for AR10 calibers range from 16″ up to 24″. Although 20″ seems to be the sweet spot for the 308, with the right barrel, you can get away with using a 16″ barrel.

How accurate is a 308 16-inch barrel?

A 16″ barrel will do you just fine until you get out to and past 600 yards. Unfortunately, the 308 round will drop significantly past 600 yards, so if you’re going to be engaging targets at distances past 600 yards, you’d be better off with a 20″ barrel.

Is an 18-inch barrel good for an AR-10?

Most 308 WIN loads get full powder burn at roughly 18 inches of barrel length. So for a general-purpose AR10 build, an 18-inch barrel will do you just fine.

However, even in 18-inch barrels, the profile and gas system length can determine weight. 18-inch barrels can range from a Faxon pencil to a thicker Big Gunner profile and come in both mid and rifle-length types.
