Polymer 80 Glock 19 Complete Frame Kit

This listing is for the Polymer 80 Glock 19 frame kit, a precision-engineered component platform designed for builders who require exacting tolerances and MIL-spec material integrity. As a non-serialized, partially completed frame, this product allows the user to finish the lower receiver using standard hand tools, resulting in a firearm component that meets all federal guidelines for personal manufacture. The Polymer 80 Glock 19 platform has become the industry benchmark for DIY firearm construction, offering the same ergonomics and aftermarket compatibility as factory-produced equivalents. Every frame is manufactured from high-impact, glass-reinforced polymer and includes all necessary jigs, bits, and pins to complete the build.

Overview

The Polymer 80 Glock 19 frame is a 80% lower receiver that requires final machining of the trigger housing pocket, fire control pocket, and pin holes. This kit includes the polymer frame, a high-strength steel jig, drill bits, end mill, and all LPK pins. The frame is designed to accept all standard Gen 3 Glock 19 internal parts, slides, barrels, and magazines. Each unit is serial-number free at the time of purchase, placing the responsibility of compliance with the end user regarding local, state, and federal laws. The Polymer 80 Glock 19 frame is manufactured in the USA and tested for fitment against OEM specifications.

Who It Is For

This product is intended for the experienced firearm builder who understands the legal and mechanical requirements of completing an 80% lower receiver.
