Machined from 416R stainless steel with 6-groove, hand lead-lapped button rifling, this barrel delivers a smooth bore finish and excellent bullet-to-rifling contact for improved consistency and extended barrel life. Designed around the Centurion MK11 platform, the barrel features a 1:7.5" twist rate, rifle-length gas system, a .875" gas block journal with an alignment tab, and a 5/8x24 threaded muzzle for muzzle devices.
