Faxon Firearms
The Faxon Firearms Match 6mm ARC barrel is a precision rifle barrel built for shooters who demand accuracy without compromise. Built from 416-R stainless steel and manufactured in-house from gun-barrel-quality stock, this 20-inch heavy-fluted barrel delivers the consistency you need for competition, long-range hunting, or precision rifle work. The 1:7.5 twist rate is optimized for the 6mm ARC cartridge, and the 5R hybrid rifling—with lands positioned opposite grooves and reduced sharp angles—minimizes bullet jacket deformation to boost velocity and simplify cleaning.
What sets this barrel apart is the attention to durability and fit. The bore and exterior receive a complete salt bath Nitride treatment, which hardens the steel, extends barrel life, and resists corrosion from the elements. The M4 barrel extension is coated in Nickel Teflon, maintaining excellent dry lubricity and corrosion resistance while improving the fit between extension and receiver for tighter tolerances and better accuracy. Every barrel is magnetic particle inspected and finished with a recessed target crown—the kind of quality control you expect from a match-grade component.
The heavy-fluted contour reduces overall weight while keeping rigidity where it matters, and the .750" gas block diameter with 1.9" journal length accommodates standard AR platform components. Threading is 5/8x24 TPI, compatible with most modern muzzle devices. At 1.57 pounds, this barrel balances the durability needed for serious shooting with the handling you want in a modern sporting rifle.

The Faxon Match barrel features a 1:7.5 twist rate, which is optimized for the 6mm ARC cartridge and suitable for the range of bullet weights commonly used in that caliber.
Yes. The barrel uses a standard M4 barrel extension and accepts common AR platform components. The gas block diameter is .750 inch with a 1.9-inch journal length, and the muzzle is threaded 5/8x24 TPI, accommodating most modern muzzle devices.
5R is a hybrid rifling pattern with lands positioned opposite grooves and reduced sharp angles compared to traditional four-groove rifling. This design reduces deformation of the bullet jacket, which improves velocity and makes the bore easier to clean.
The bore and exterior receive a complete salt bath Nitride treatment for hardness and corrosion resistance. The M4 barrel extension is separately coated with Nickel Teflon, which provides excellent lubricity, corrosion protection, and improves the fit between extension and receiver.
