Built from 4150 CMV steel, this button-rifled barrel is treated with a black nitride finish both inside and out for superior corrosion resistance and extended barrel life. The 1:8” twist rate provides excellent stabilization across a wide range of 5.56 NATO and .223 Rem bullet weights, making it a versatile choice for both defensive and range applications.
The Gunner profile combines a Government-profile chamber section with a pencil-profile front, reducing weight without sacrificing durability where it matters most. The barrel is threaded with a 1/2x28 muzzle pattern, ready for brakes, flash hiders, or suppressors.
