80% Lower

80% Lower

The 80% lower is a vital component for any do-it-yourself AR-15 build. An 80% lower receiver provides the builder an opportunity to complete their own custom AR-15 rifle without any paperwork or FFL (Federal Firearm License) transfer. By definition of the law, an 80% lower is NOT considered a firearm since it is not 100% completed. By design, the 80% lower still requires the builder to complete the last 20% of milling. Typically, the completion of an 80% lower receiver is accomplished using an 80% lower jig.

While the 80% lower receiver allows a builder to complete a firearm themselves, this also allows the builder to build a rifle that does not require registration with the government since no serialization is required (although recommended). You can simply order it and we send it right to you without any of that clunky government oversight.

There are several types of 80% lower receivers available to AR builders. The types of lowers that are popular in the AR enthusiast community are: polymer 80%, billet, forged, cast and 80% lower and 80% jig packages. Each type of lower provides its own benefits, but, ultimately, depends on what the builder is looking for in their AR-15 build.

- Minimal technical skills required to complete
