We begin with a 7075 T6 Aluminum alloy forging, which is then CNC machined to give us one of the best lower receivers made.  We incorporate the latest reinforcement area around the front pivot pin and reinforcing ridge over the buffer tube area, as well as the full fence around the magazine catch button to minimize accidental magazine release.  Our lowers are finished with a black hard coat anodization for maximum durability.
