Quench Polish Quench (QPQ) is a specialized type of nitrocarburizing case hardening that increases corrosion resistance. It is sometimes known by the brand name of Tufftride, Tenifer Black Nitride or Melonite. QPQ is a huge improvement over Chrome Lined barrels. Unlike chrome lining, where the chrome is built up on the surface, QPQ converts the surface without the risk of dimensional build up. The technique is used when two or more of the following properties are required in a work piece:

Length - 16"

Finish - QPQ Corrosion Resistant
Gas System Length - Mid
Gas Block Journal - .625″ Gas Block Journal
