Barrel: A proprietary blend of Hammer forged chrome molly vanadium made by FN that is referred to as "Machine Gun Steel" by virtue of its required use in FN's M249 and M240 weapons. The hammer forging process work hardens the steel, making it more durable. In addition, the chrome process for the bore allows for a lining almost twice as thick as a standard M16 for enhanced durability. Chambered in 5.56 NATO, with a 1/7 twist, M4 barrel extension, and a rifle-length gas system. The barrel has a conventional .750" gas block diameter, is Mil-spec phosphate coated, High Pressure tested and Magnetic Particle inspected. Barrels are finished off with a taper pinned, f-marked, front sight post, standard handguards, and an A2 flash hider. Barrel is made for PSA by FN right here in South Carolina.
