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

The Faxon .223 Wylde 20″ Heavy Fluted 5R Match Series Barrel is purpose-built for marksmen and precision AR-15 builders who demand outstanding accuracy, heat management, and durability. Engineered from 416R stainless steel and enhanced with a QPQ Nitride finish, this barrel features aggressive straight fluting to reduce weight and increase surface area for improved cooling during extended shooting sessions. The result is a high-performance barrel that shoots flatter and stays cooler under pressure.

Chambered in .223 Wylde, this barrel provides exceptional accuracy and compatibility with both .223 Remington and 5.56 NATO ammunition. The 5R rifling design helps reduce copper fouling, minimizes jacket deformation, and enhances bullet stabilization, resulting in improved velocity and tighter shot groups—ideal for competitive shooters, varmint hunters, or anyone looking to stretch the effective range of their AR platform.

The Faxon .223 Wylde 20″ Heavy Fluted 5R Match Series Barrel is equipped with a rifle-length gas system for smooth cycling and optimal recoil control. It also includes a 0.75″ gas block journal and a Nickel Teflon coated M4 feed ramp extension to ensure reliable feeding and corrosion resistance in all conditions.

What makes 5R rifling superior?

Unlike traditional rifling, 5R rifling uses five lands and grooves with sloped sides that reduce bullet distortion and fouling. This leads to less drag on the projectile, cleaner barrels after extended use, and enhanced barrel life—perfect for high-volume shooters who prioritize accuracy over the long haul.

Why choose a heavy fluted profile?

Faxon’s heavy fluted barrels retain the rigidity and thermal stability of a heavy barrel while significantly reducing weight. In fact, these barrels are nearly 16 ounces lighter than their non-fluted counterparts. The straight fluting not only improves aesthetics but also helps shed heat and balance the rifle more effectively—especially important for long-range precision builds or sustained fire applications.
