The DPMS Kitty Kat complete upper is a compact .300 AAC Blackout AR-15 upper with a 7.5-inch heavy barrel, a 6.5-inch quad rail and a pistol-length gas system (DPMS part no. DP51655170308). DPMS builds the barrel from chrome moly vanadium steel with a nitride finish and a 1:7 twist, and adds a .750 low-profile gas block and an A2-style flash hider threaded 5/8×24. The forged 7075-T6 A3 upper is hard coat anodized black and made to mil-spec, and the upper is supplied with a mil-spec bolt carrier group and charging handle. For a builder who wants a short .300 Blackout upper without piecing parts together, it is a ready-to-mate answer.
