General Barrel Info: The barrel on an AR-15 pistol operates through a 'gas impingement' system, where gas is tapped from off the barrel and cycled back through a connected gas system to help the bolt carrier extract a spent cartridge. Pistol length AR-15 barrels come in two gas lengths, Pistol, Carbine, & Mid-Length. AR-15 Pistol barrels can be chambered in a variety of different calibers from rifle to pistol cartridges. Thanks to the modularity of the AR-15 platform, your next pistol will be incredibly easy.

About This Barrel: This 10.5" Faxon Barrel is made from 4150 CMV. It is also chambered in the 7.62x39 caliber. The unique gunner profile is a mixture of the government and pencil profiles giving this barrel a unique shape and advantage ballistically. This barrel also comes with a 1:8 twist rate and a 5/8x24 thread pitch.
About the Profile: Gunner - The gunner barrel profile is lightweight under the handguards, until just before the gas port. After the gas port, it gets heavier, out to the muzzle. It is also designed to reduce the weight on the front of the rifle significantly, by removing as much material as necessary to retain a structurally sound barrel. Pencil barrels are a perfect choice for your next weight-saving build!
