AR15 80 Lower

AR15 80 Lower

The AR15 80 Lower is a crucial part of any AR15 build. An AR15 80 lower receiver provides the builder an opportunity to complete their own custom AR-15 rifle or pistol without any paperwork or FFL (Federal Firearm License) transfer. By definition of the law, an 80% lower receiver is NOT considered a firearm since it is not 100% completed.

Not Considered a Firearm

The 80% lower is a foundational piece of any custom AR15 build. The AR15 80 lower itself is the key to building not only a custom rifle, but also thee route to build a rifle WITHOUT an FFL (Federal Firearm License) transfer or paperwork, in general. According to the definition of the law, the 80% lower is not considered a firearm since it is only partially complete. The 80% lower requires the builder to finish the last 20% of millwork resulting in a 150% completed lower receiver. This is accomplished with the help of an AR15 Jig – providing the builder with templates, depth guides, sidewalls, etc. as a fool-proof completion method.

Modular and Universally Compatible

There are countless manufacturers of AR15 80 lowers on the market today. Since the AR 15 is based on a military-issued rifle, from a manufacturing specifications perspective, it is a “plug-and-play” friendly platform with standardized components; upper receiver, triggers, etc. Therefore, it is easy for builders to find AR 15 Parts they plan to add to their AR15 rifle build.
