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 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. 14.7" length, M4A1 profile, 5.56 NATO chamber with a 1:7 twist, MPI & HPT, chrome-lined, carbine-length gas port, and M4 feedramps. Barrels are finished off with a taper pinned, f-marked, front sight post, standard handguards, and an A2 Flash Hider. The 14.7 inch length allows for the use of a standard A2 flash hider pinned to the barrel to bring the barrel length to minimum legal rifle length of 16 inches. This upper is not pinned and welded.
