"Ready to assemble into AR15 rifles. Olympic receivers are known for quality construction and are a good value. Require shipment to FFL dealer and firearm background check. The foundation on which every standard AR/PCR style rifle we make (only excpetion is the Plinker) is the forged 7075 T6 lower receiver, cut on CNC machines to mil-spec tolerances or better. All standard mil-spec (meaning non-Colt's) AR parts will fit in these receivers, including standard hammer and trigger pins and front pivot pins. "
