NEW FRONTIER ARMORY C45 80% LOWER RECEIVER

New Frontier Armory C45 80% lowers can be milled and drilled to accept common AR-15 lower parts kits, and non-standardized parts such as the magazine release and ejector come installed from the manufacturer, meaning you won’t need to chase those down individually.  Accepts most .45ACP or 10mm AR style upper receivers and uses Glock pattern .45ACP or 10mm magazines.
