Uppers & Lowers

Uppers, lowers and receiver sets in Mesa, Arizona — complete upper assemblies, stripped and complete lowers, and matched receiver sets for AR-pattern builds. A lower receiver is legally the firearm and transfers through an FFL like any other; uppers generally do not.

Configuration carries legal consequences, particularly barrel length and overall length. If you are building rather than buying complete, talk to us first — the order you assemble things in can matter.
