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 workpiece:

• Length - 20"
• Material - 4150 Chrome Moly Vanadium
• Profile - Goverment
• Finish - QPQ Corrosion Resistant
• Gas System Length - Rifle-Length
• Gas Block Journal - .750" Gas Block Journal
• Twist Rate - 1/7 Twist
• Muzzle - 1/2x28 Threaded
• Weight - 35oz
