Faxon Firearms 12" 8.6 BLK Big Gunner Profile,
Pistol Gas, 1:3T, 4150, Nitride, M18x1.5 TPI Barrel
General Barrel Info: The barrel on an AR-10/ LR-308 pistol operates through a 'gas impingement' system, where gas is tapped from off the LR-308 barrel and cycled back through a connected gas system to help the bolt carrier extract a spent cartridge. Pistol length LR-308 barrels come in two gas lengths, Pistol, Carbine, & Mid-Length. AR-10 Pistol barrels can be chambered in a variety of different calibers from rifle to pistol cartridges. Thanks to the modularity of the platform, your next pistol will be incredibly easy.

About This Barrel: This barrel from Faxon Firearms is chambered in 8.6 Blackout which channels rotational energy to increase energy on-target. These barrels have been air-gauge and MPI tested to ensure accuracy and reliability. It is machined from 4150 CMV with a salt bath nitride finish to make it durable. It has a big gunner profile and operates on a pistol gas system.
Barrel Classification: Pistol
Length: This Barrel is designated as a pistol length barrel with an overall length of 12".
Caliber: 8.6 Blackout was developed by Kevin Brittingham and his team at Q. It is often referred to as 300 Blackouts big brother and its easy to see why. What 300BLK provided to the AR-15 platform, 8.6BLK does for AR-10â€™s. The parent case being 6.5 Creedmoor, 8.6BLK is trimmed down and necked up for a .338 projectile. Heavier mass means more energy transfer on target. Barrels are being run with a fast 1:3 twist, creating devastating terminal performance.
Material: 4150 CrMoV - Chrome-Moly Vanadium, or simply ""CMV"", is the official mil-spec gun steel developed by Colt Firearms for the military-issued M16 and M4. It contains the same elements as 4150 steel. It also contains Vanadium. Vanadium significantly increases the strength, hardness, and high-temperature stability of the steel.
Finish: Nitride - Nitriding is a process during manufacturing that diffuses nitrogen into the steel to make a case-hardened surface for improved resistance and strength. A Nitrided barrel typically has a gloss black texture.
