The Faxon Firearms Gunner Profile Barrel (brand part number 15A38P7NGQ) is a 7.5-inch .300 AAC Blackout AR-15 barrel finished in black matte, rifled with a fast 1:8 twist to stabilize heavier subsonic and supersonic .300 BLK loads alike. It’s cut with a carbine-length gas port and a .750 gas block diameter, and Faxon finishes the muzzle with an 11-degree target crown for improved accuracy. The barrel is threaded and ships without sights or fluting, sold as a bare barrel for builders.
