Barrel and Gas System

The 10-inch 4150 Chrome-Moly Vanadium barrel features a 1:8 twist rate optimized for modern ammunition weights. A Black Nitride finish provides corrosion resistance and durability. The pistol-length Direct Impingement gas system delivers reliable operation while maintaining a compact profile. An A2 flash hider (5/8 x 24 threads) manages muzzle signature.
