At 80 Lowers, we build precision quality AR9 80% Lower Receivers that are CNC machined from billet aluminum. A 9mm 80% Lower is completed by the customer, which is the starting point for a custom rifle build.

Our AR9 80% Lower Receivers are designed to accept the Colt style magazines, and work as the original Colt pattern AR15 Lowers were intended. Our 9mm 80% Lowers also have the rear pocket already machined for you, and our 80% Lower Jigs reflects this condition as well.
