The Polymer80 P80 Thr/Flu Brl N/Sght 15rd is a factory-assembled component designed specifically for builders seeking a reliable drop-in solution.

Overview

This P80 Thr/Flu Brl N/Sght 15rd assembly integrates a 416 stainless steel barrel with a 1/2×28 threaded muzzle, fluted profile for reduced weight, and tritium night sights for low-light visibility. The barrel is heat-treated and precision-rifled for accuracy, while the slide is machined from billet 17-4 stainless steel with a nitride finish. The included 15-round magazine is compatible with standard compact frames. This is a complete slide and barrel package that simplifies a P80 build or serves as a direct replacement for compatible platforms.

Who It’s For

This product is intended for experienced builders and shooters who are assembling a Polymer80 frame or upgrading an existing compact build.
