Build Kits & Receivers

AR-15 build kits, stripped and complete upper receivers, and stripped lower receivers from Bravo Company, Faxon, Radian, Rise Armament, LWRC, SA-15 and Battle Arms Development. Rifle-length, carbine and pistol kits, and the individual receivers for people building from parts.
Uppers, build kits and parts ship to your door. A stripped lower receiver is the serialized part and is a firearm under federal law, so it transfers through your local FFL exactly like a complete rifle. Our FFL transfer guide explains that process. If it is your first build, start with a complete upper and a stripped lower and you avoid the headspace and gas system questions entirely.
