The polymer 80% gunsmithing kit represents the newest, easiest way to build a factory-spec handgun or polymer AR-15 at home. These 80% pistol frames and 80% receivers include American-made, affordable units with the necessary jig and tooling to cut and drill your blank, turning it into a firearm that’s ready for final assembly.

Available Polymer80 Pistol Kits
