Faxon Match Series 20" Spiral Fluted .308 WIN 416R SS Nitride 5R Rifle-Length Barrel

Faxon Match Series 20″ Spiral Fluted .308 WIN 416R SS Nitride 5R Rifle-Length Barrel

The Faxon Match Series 20″ Spiral Fluted .308 WIN 416R SS Nitride 5R Rifle-Length Barrel is designed to deliver long-range precision and rugged durability in an elegant, performance-driven package. Crafted in-house from premium 416R stainless steel, this barrel is optimized for the AR-10 platform and built to meet the needs of competitive shooters, hunters, and precision marksmen. The spiral fluting not only adds visual appeal—it reduces overall weight, improves balance, and increases surface area for faster heat dissipation during prolonged firing sessions.

With a 20-inch length and rifle-length gas system, this barrel provides superior muzzle velocity, enhanced dwell time, and smoother cycling. Chambered in .308 Winchester, it handles a wide range of factory loads and handloads with consistent performance. The 5R button rifling paired with a 1:10 twist rate stabilizes a variety of bullet weights, particularly match-grade projectiles in the 150 to 175 grain range. The rifling profile also reduces jacket deformation and fouling, contributing to increased barrel life and easier maintenance.

The bore and exterior are treated with a salt bath nitride finish, delivering exceptional corrosion resistance and surface hardness while maintaining match-grade tolerances. A .750″ gas block journal ensures compatibility with most low-profile gas blocks, while the 5/8×24 TPI muzzle threading supports your choice of compensators, brakes, or suppressors. At the muzzle, a recessed 11-degree target crown ensures consistent gas exit and contributes to exceptional accuracy shot after shot.

The barrel features an M4 barrel extension with a Nickel Teflon NP3 coating for smooth lockup and added corrosion protection. Weighing approximately 2.75 lbs, this spiral fluted profile maintains the rigidity needed for precision shooting without the excessive weight of a full heavy-contour barrel.
