Building your own tack driving AR-15 from the ground up has never been easier with our own American Armament Co. stripped lower. High strength, CNC precision machined and hard coat anodized black for a long lasting, durable finish. Extra reinforcement around the front pivot pin, reinforcing ridge over the buffer tube area and a full fence around the magazine catch button ensure that these lowers are built for a lifetime of heavy-duty use. The bolt catch uses a stainless steel rod. This method uses a set screw instead of traditional roll pin designs. The rear takedown pin and detent uses the same design as our upgraded bolt catch system. Set screws and stainless steel rods included. Texas State Flag is engraved on left side. Safe, fire and auto is engraved on both sides for guns with ambi safeties. Aircraft Aluminum Alloy Tempered to T6 Condition.
