What is an 80% Lower Receiver?

Officially called a “receiver blank” by the Bureau of Alcohol, Tobacco, and firearms (ATF), an 80% lower is an unfinished receiver that isn’t considered a firearm under federal law. Cutting and drilling the lower at home with hand tools turns it into a ready-to-build firearm by legal definition. Whether it’s an AR-15 80 lower or AR-10 80 lower, thousands of shooters have built reliable and accurate rifles and pistols with our units.
