Performance and Reliability

The 1:7 twist rate stabilizes a wide range of 5.56 NATO ammunition, from lighter 55-grain loads to heavier 77-grain rounds. The A2 flash hider reduces muzzle flash, an important consideration for low-light shooting or tactical applications. Manganese phosphate finish provides corrosion resistance and a classic military appearance.
