Description
Upgrade your precision gas-gun build with the Centurion Arms MK11 16″ 6.5 Creedmoor barrel — a purpose-built, match-grade barrel engineered for repeatable accuracy and reliable gas system performance. 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 5/8×24 threaded muzzle for muzzle devices. The .875″ journal includes Centurion’s alignment notch (but will also accept any standard .875″ gas block), making gas-block installation precise and repeatable. With a .094 gas port and hefty profile that can serve as an HBAR option, this 16″ barrel balances rigidity and weight for enhanced down-range performance.
