Always Armed 16" Straight Profile Barrel 9mm - 1/2x28 ***OVERRUN*** - $56.51 after Code: LUCKY13

Description

This 9mm chambered 16 inch Barrel is machined from 4150 Chrome Moly Vanadium steel with a QPQ Corrosion Resistant Finish and QPQ coated barrel extension.

Quench Polish Quench (QPQ) is a specialized type of nitrocarburizing case hardening that increases corrosion resistance. It is also known by the brand names of H&M Blacknitride+ (black nitride), 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 makes your gun’s metal 10 times stronger than it was originally, increases the velocity of your barrel by a few hundred feet-per-second, and slickens the surface to make your gun extremely lubricated.

Features:

Designed to work with both Colt/RR and Glock style AR builds
Compatible with standard mil-spec uppers and dedicated uppers
9mm on an AR15 platform operates by blowback and does not need a gas block or gas tube
Integrated feed ramp and barrel extension
IMPORTANT: A .223/5.56 flash hider will not have enough clearance for a 9mm round to pass
Before installing a muzzle device, ensure a 9mm round will drop freely through the muzzle device bore

*These barrels have no index pin or dedicated feed ramp.
