The Rock River Arms LAR-15M CAR A4 (Rock River Arms part no. BLK1222) is a .300 AAC Blackout AR-15 built for shooters who want both suppressed and unsuppressed performance from the same platform. Rock River Arms threads the 16-inch chrome moly barrel for an A2 flash hider, and pairs it with a two-stage match trigger for a crisper break than a mil-spec unit. The R4 handguard and RRA Tactical CAR stock round out a rifle built for the range, hunting, or home defense, with an overmolded A2 grip for a comfortable, secure hold.
