"WMD AR-15 BEAST Distressed ""Battelworn"" chambered in 5.56 NATO. The finish is created by specially applied nickel boron coating that yields the visual appeal of a distressed finish. It features an ambidextrous billet AR-15 with a match-grade barrel, a large, flared magwell with front finger rests, and a crisp, smooth trigger. The match-grade barrel is cold hammer forged chrome moly vanadium steel with a mid-length gas system, ½-28 threads at the muzzle, and a deep black nitride finish for longevity. It has a 12-inch free-floating tactical handguard with M-LOK slots and a full-length top picatinny rail. The handguard, upper and lower are all covered inside and out with our deep gray battleworn nickel boron finish for an unmistakable look. Factory new in box."
