16" M4 AR-15 5.56 .223 Carbine Barrel + Premiere Manufacturing Titanium Nitride (TiN) Bolt Carrier Group - Gold

Barrel Info:

This 5.56 chambered 16" M4 Profile Barrel is machined from 4150 Chrome Moly Vanadium steel with a QPQ Corrosion Resistant Finish and QPQ coated M4 feed ramp extension.

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.
