The AR-9 Super Lower is a 3D printable lower receiver designed to use Glock magazines. It uses the same steel buffer band and support rib as our AR-15 lowers to provide the needed level of durability. It is compatible with most AR-9 upper receivers. Due to the reinforcement on the right side it is not compatible with ambidextrous safety selectors. The ejector and mag catch are designed to be 3D printed. This design includes custom support.
