QPQ Corrosion Resistant’s a barrel finish achieved through a Quench Polish Quench (QPQ) nitriding process, which significantly enhances hardness, corrosion resistance, and surface smoothness. This finish’s commonly applied to AR-15 and AR-10 barrels, bolt carrier groups, gas blocks, and other steel firearm components. QPQ treated parts are popular among shooters and builders for their exceptional durability, easy maintenance, and long lasting protection against wear and rust.
