18" 6.5 Creedmoor 1:8 Twist AR-10 Barrel

Unlock maximum long-range performance and precision with the 18" 6.5 Creedmoor 1:8 Twist AR-10 Barrel. Purpose-built for precision marksmen, long-range competitors, and big-game hunters, this barrel optimizes the flat-shooting ballistics of the 6.5 Creedmoor cartridge out of the AR-10 platform.

Crafted from premium 4150 Chrome Moly Vanadium steel, this heavy barrel profile delivers outstanding thermal stability and rigidity, minimizing barrel whip and point-of-impact shift during rapid or extended firing strings. Featuring a versatile 1:8 twist rate, it perfectly stabilizes popular medium-to-heavy match projectiles (ranging from 120gr up to 147gr+) for tight shot groupings at extreme distances.

The rifle-length gas system works in tandem with a heavy-duty .936 gas block journal to ensure soft, smooth cycling with reduced felt recoil. Outfitted with standard 5/8x24 TPI muzzle threads, it easily accepts your preferred muzzle brake, compensator, or suppressor.
