FAXON FIREARMS 10.5" GUNNER BIG BORE PROFILE AR15 BARREL, .458 SOCOM, PISTOL LENGTH, 4150 QPQ
Faxon Firearms barrels are the pinnacle of value. 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.
