5R rifling, 11-degree target crown, MPI inspected.

The Faxon .223 Wylde 18″ Heavy Fluted 5R Match Series Barrel is designed for shooters who demand superior accuracy, reliability, and durability from their rifle build. Crafted from 416R stainless steel, this barrel features aggressive straight fluting that reduces weight without compromising rigidity. The heavy profile provides excellent thermal resistance and repeatable precision shot after shot—ideal for competition and long-range engagements.

Faxon’s 5R rifling improves bullet stability by reducing jacket deformation and fouling, which helps increase velocity and maintain accuracy over extended sessions. The QPQ Nitride finish adds enhanced corrosion and wear resistance to both the bore and exterior, while the Nickel Teflon coated M4 feed ramp extension ensures smooth and reliable cycling with a variety of ammunition types.

This barrel is chambered in .223 Wylde, making it compatible with both .223 Remington and 5.56 NATO ammunition while offering match-grade precision. The rifle-length gas system contributes to smoother recoil and improved reliability in various shooting conditions, while the 0.75″ gas block journal supports a wide range of aftermarket components.

Why choose a heavy fluted barrel?

Faxon’s heavy fluted design strikes a perfect balance between weight and performance. By removing excess material via fluting, the barrel sheds nearly 16 ounces compared to non-fluted heavy barrels—without giving up accuracy or strength. This reduction in forward weight improves handling while maintaining the thermal stability required for rapid or sustained fire.
