The Polymer80 PF45 80% Pistol Frame ONLY comes complete with essential parts as described: Polymer80 PF45 80% Pistol Frame Only The Polymer80 PF45 80% Pistol Frame Only represents the next step for builders seeking a full-size platform that accepts large-frame components. This uncompleted frame requires finishing and assembly, giving you the ability to create a custom firearm built to your specifications. Designed to accommodate .45 ACP and 10mm builds, the PF45 frame is machined from high-strength, impact-resistant polymer and includes the necessary jig and tooling to complete the frame at home. Overview The polymer80 pf45 80% pistol frame only is a raw, unfinished lower receiver that allows you to mill out the remaining material to accept standard large-frame parts kits. Unlike complete frames, this 80% variant requires no serial number and no FFL transfer for the unfinished component. The frame itself is the core of the build, and the PF45 pattern is specifically engineered for full-size, high-caliber pistols. When you purchase this polymer80 pf45 80% pistol frame only, you receive the frame blank, a universal jig, drill bits, end mill, and instruction manual. This is the correct platform for those who want a large-frame pistol without the restrictions of a fully serialized receiver.
