FAXON Duty Series 16in HBAR 5.56mm NATO Mid-Length 4150 QPQ Nitride Barrel (15A58M16NHQ)

Manufactured in-house, the FAXON Duty Series 16in HBAR 5.56mm NATO Mid-Length 4150 QPQ Nitride Barrel is fully stress relieved, air-gauge tested, and 11 degree target crowned to ensure superior accuracy.

Quality is imbued into Faxon's barrels from the start. They 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.
