AOA Duty Series Ported Barrel for Glock® 19

Made in the USA – NonThreaded & Ported

AoA Duty Series Ported Barrel for G19 are Non-Threaded barrel drop-in replacements compatible with your 9mm P80 PF940C or G19 with a windowed slide. Our G19 compatible barrels are 100% manufactured in the U.S.A from 416R Stainless Steel, feature standard rifling, and are finished in your choice of finish. Arm or Ally Duty Series products feature everything you need and nothing you don’t. If you’re looking for a high-quality product, with classic, timeless styling, this is the barrel for you.

This barrel features 8 ports at the 12 O’Clock position. The 8 ports are designed to allow faster follow-up shots and reduced recoil by allowing the expanded gasses to escape against the direction of recoil.

Note: This barrel MUST be used with the matching AOA Top Windowed Slide Here.  This ported barrel’s misuse may result in severe injury and property damage.  This part should be installed by a qualified armorer/gunsmith.  We are not responsible for ANY damages.  Furthermore, the burning gases that exit the ports are scorching! If you are shooting from a retention stance or with the weapon tucked close to your side, the burning gasses can cause harm to you.
