The Daniel Defense MK12 SPR CA Compliant is a precision-focused AR-style rifle chambered in 5.56 NATO. Its 18-inch heavy-profile barrel uses a rifle-length direct impingement gas system and a 1:7-inch twist rate to support accuracy with a broad range of 5.56 NATO loads. A 12-inch free-floating quad-rail handguard provides mounting space for lights, lasers, bipods, and other accessories without placing pressure on the barrel. The rifle is fitted with a GRIP-N-RIP charging handle, a Geissele SSA two-stage trigger, and a fixed glass-filled polymer stock with soft-touch overmolding. This California-compliant model includes one 10-round magazine.
