DPMS Kitty Kat Upper | .300 AAC Blackout | 7.5in | DP51655189388

The DPMS Kitty Kat complete upper is a compact AR upper assembly built around a 7.5-inch nitride-treated barrel chambered for .300 AAC Blackout. It combines a forged 7075-T6 C7 carry-handle upper machined to MIL-SPECS with a pistol-length gas system and a mil-spec bolt carrier group. The configuration includes A1 rear sight geometry, an R-marked front sight gas block, and an A2 flash hider for conventional AR compatibility.
