The Genesis Arms Gen-12 SBM 10.5-Inch is a compact, semi-automatic 12 gauge built on an AR-pattern platform with a GEN1 DPMS .308-pattern lower. Genesis Arms gives it a 10.5-inch barrel, a factory blast can with a crown muzzle device and 1.375-24 muzzle threads. The short recoil system cycles the action without a gas system, and the free-float M-LOK handguard sits under a full-length Picatinny rail. A Hogue rubberized grip, a mil-spec AR trigger and a right-side charging knob complete the controls. It ships with a 5-round magazine and a soft case.
