20" 6.5 Grendel 1:8 Twist Barrel

Maximize long-range reach and terminal performance on your lightweight hunting or target rig with the 20" 6.5 Grendel 1:8 Twist AR-15 Barrel. Purpose-built to push the AR-15 platform to 1,000 yards and beyond, this barrel optimizes the flat-shooting ballistics and high sectional density of the popular 6.5 Grendel cartridge.

Forged from premium 4150 Chrome Moly Vanadium (CMV) steel, this heavy contour barrel provides the stiffness and thermal stability required to maintain shot-after-shot precision during extended target sessions or field use. The interior and exterior are treated with a corrosion-resistant black nitride finish, which significantly reduces friction, eases barrel cleaning, and extends rifling life.

Featuring a versatile 1:8 twist rate, this barrel effortlessly stabilizes popular match and hunting bullets (ranging from 90gr to 130gr+). The rifle-length gas system paired with a standard .750 gas block platform provides exceptionally smooth cycling and soft recoil impulse. Standard 5/8x24 TPI muzzle threads allow effortless attachment of your favorite suppressors, muzzle brakes, or compensators.
