Faxon Firearms Match Series .338 ARC 11.5" 1:5 Twist Gunner Profile AR-15 Barrel - Black Nitride

The Faxon Firearms Match Series .338 ARC barrel is engineered for AR-15 platforms running the .338 Advanced Rifle Cartridge in compact pistol and SBR configurations. Cut from 416-R stainless steel with a 5R button-rifled bore and finished inside and out in QPQ black nitride, this 11.5" barrel carries the Gunner profile, a hybrid contour that trims weight ahead of the gas block while retaining a stout section under the handguard.

A fast 1:5 twist rate stabilizes heavy .338 ARC projectiles, and a pistol-length gas system ensures reliable cycling in short configurations. The barrel is set up with 5/8x24 muzzle threads for compatibility with the wide range of .30-caliber muzzle devices and sound suppressors. This Match Series barrel delivers consistent performance and accuracy for hunting, suppressed shooting, and AR-15 pistol builds.
