Centurion MK11 308WIN Stainless 16″ Barrel

Take your AR-10/LR-308 build to the next level with the Centurion Arms MK11 .308 Winchester stainless steel barrel — a precision-engineered, match-capable barrel designed for accuracy, durability, and consistent performance in competition, hunting, and tactical roles.

Made from heat-treated 416R stainless steel and hand lead-lapped with 5R button rifling, the MK11 delivers a refined bore finish for improved bullet-to-rifling contact and tighter groups. A rifle-length gas system provides smooth cycling and a softer recoil impulse, while the 1:10″ twist rate stabilizes a wide range of .308 bullet weights from light match loads to heavier hunting projectiles. Threaded 5/8×24 at the muzzle for suppressors or muzzle devices, and built on a standard .875″ gas block journal, the MK11 is engineered for straightforward installation on DPMS-pattern AR-10 platforms.

Available in multiple lengths to suit your build and mission, the Centurion MK11 .308 WIN barrel is an ideal upgrade for precision gas-gun builds that demand repeatable performance.
