AR15 lower receiver with fire control parts including hammers, selectors, springs, and bolt catch.  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 and teflon coated for maximum durability. 

The lower receiver parts are made by various military contractors, for example the fire control parts, mag catch, detents, and pins are made by the same contractors that top ar-15 manufacturers use.  Bolt catches and selectors are made by the same contractor that supplies BM.  They are made to military specs other than the AR dimensions ( not M-16 ) on the lower receiver parts.  The lower receiver parts for the M-16 rifle come from the same manufacturer as made for the M-16 rifle.  Everything is first rate parts, not seconds, and made in the U.S.A.
