Faxon Duty Series 10.5″ 5.56 NATO Carbine-Length AR15 Rifle Barrel, 4150 QPQ Nitride for AR15/Raven/WK180/Crypto
Manufactured in-house, these barrels are fully stress relieved, air-gauge tested, and 11 degree target crowned to ensure superior accuracy.
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.
