300 BLK with pistol gas system for optimum reliability with super or subsonic ammo. The Gunner profile is a blend of two of the best performing profiles of all time, Gov’t and Pencil. Faxon Firearms barrels are the pinnacle of value.

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.
