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 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:

  • wear resistance
  • corrosion resistance
  • lubricity
  • fatigue strength

5 of 5 An updated bbl standard March 19, 2017
Reviewer: Mike Dismuke from Waxhaw, NC United States  
For years I have always thought that a military pattern rifle must be chromed lined.  And for years this was certainly true.  But times change.  There is newer technology out there that may very well replace chrome lining.  QPQ or "melonite" is revolutionizing the industry.  You can now have a bbl of the same quality for a substantial reduction in price.  I am very impressed with the quality from BA  and the service from RTBA&S.  I have found a new go-to vendor and supply.   Highly recommended.
