Our AR-15 and AR-308 80% lower receivers can be shipped directly to your home because they are not considered firearms per the ATF's definition. In order for them to become functional firearm components, they require some basic machining and drilling which can easily be completed in 45 minutes or less with our innovative AR-15 and AR-308 Router Jigs. 80% lowers require the fire control group pocket to be milled out, which is completed with a handheld compact router. A hand drill or a drill press can be used to drill the safety selector, hammer, and trigger pin holes. We offer a variety of billet and forged AR-15 80% lower receivers of the highest quality. All of our products are proudly made in the USA to exacting standards.
