These are 10.5″ AR-15 pistol kits with a chrome moly barrel, 1:7 twist, and 1/2×28 thread, finished in Zombie Green Cerakote. They’re chambered in 5.56 NATO or .300 Blackout, with a choice of Keymod or M-LOK handguards, including house, riveted, and windowed styles. Pair one with a Zombie Green lower to complete the build.
