Faxon Firearms Duty Series AR15 Barrel 9mm 1:10 Twist 4150 Nitride – 8.5 | Light Tapered Profile | Blowback

Description

Quality is imbued into our barrels from the start.

We start with the best materials, either certified 4150 Mil-Spec steel or 416-R Stainless.

From there, each barrel goes through a battery of tests at each operation until finished in Nitride and final inspected.

All barrels are individually checked for headspace by precision custom hardened gauges.
