Crafted from 4150 CMV steel, the barrel is magnetic particle inspected (MPI) and finished with nitride inside and out for maximum corrosion and wear resistance. The 1:8 twist rate is ideal for stabilizing both supersonic and subsonic .300 BLK projectiles, making it versatile for a wide range of shooting applications. The Gunner profile reduces weight and improves maneuverability without compromising heat resistance or longevity.
The barrel includes a .750" gas block diameter, 1.9" gas journal, and M4 barrel extension for standard AR-15 upper compatibility. It also features 5/8x24 muzzle threading for attachment of suppressors or muzzle devices and an 11-degree target crown to improve precision.
