(QPQ) Quench Polish Quench is a specialized type of nitrocarburizing case hardening that increases corrosion resistance. It is sometimes known by the brand name of Tufftride, Tenifer 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.

(QPQ) is used when two or more of the following properties are required in a work piece:

· wear resistance

· corrosion resistance

· lubricity

· fatigue strength

Reviewer: Mike Vandergriend from Chattanooga, TN United States  
Bought this barrel for my latest pistol build. Have yet to shoot it but installed well. Fits tight in my reciever and fit and finish is top notch. Always use ballistic advantage barrels for my builds, excellent product at an outstanding price thanks to right to bear.
