Introducing the first truly FULL AMBI lower receiver for the AR platform. The AX556 features our right-hand bolt catch (integrated into the magazine release button), an easy to reach right hand bolt drop, a left hand magazine release (right where is should be, across from the right side mag release), and an extended bolt drop paddle to make it easier for lefties to drop the bolt without breaking their grip. This receiver also features an integrated anti-rotation hammer pin. This precision heat-treated (case 58-60 Rc) hammer pin allows the use of all aftermarket triggers and helps to eliminate creep. Our pictogram markings on the receiver accomodate either 45° or 90° safety selectors.
