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

RTB- always the best prices. BA- amazing barrels July 2, 2019
Reviewer: Kelly from Nevada  
I have had 4 different BA barrels and each has performed perfectly. The 11.5" In this version is really hard to beat.  This barrel on sale or full price is just such a great value. I worried so bought and adjustable gas block but ended up not using it and just used a standard cheap non adjustable unit out of curiosity and the barrel shoots anything I have ever used from cheap reloads, 55 to 62gr. just whatever I have at the time or find on sale. I have had this barrel for over two full years and it is by far my favorite at this point in time.

Have not got to shoot the barrel yet, but it was a tight fit on my Aero upper which is good.  Everything looks great on the barrel.  Free shipping was fast I ordered on a sunday, shipped monday, and I had it wednesday morning.
