80 Lower

An 80 lower is the foundation for any AR-15 build kit. These AR-15 lower receivers are only 80% complete (hence “80 lower”), and they do not require an FFL (Federal Firearm License) transfer. By design, the 80 lower receiver requires that the builder mill out the fire control group area, therefore, converting the 80 lower into a 100% completed AR-15 lower receiver.

All of the work required to complete the 80 lower is done using an 80 Lower Jig and basic tools such as: a standard hand-drill, drill press (optional), a basic laminate router, drill bits and end mills bits. That’s it. The work itself is very straightforward, and our kits come with instructions in both the form of video and physical paper manuals. The end-product is a fully-functional, Mil-Spec AR-15 lower receiver that is ready for installation of your AR-15 lower parts kits. In a single afternoon, you could be done milling and blasting brass at the range by dinnertime. Get to buildin’.
