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

The Faxon .223 Wylde 18″ Gunner 5R Match Series Barrel is designed for shooters who demand precision, lightweight handling, and match-grade performance in a versatile rifle platform. Machined from 416R stainless steel and finished with a QPQ Nitride treatment, this barrel offers exceptional corrosion resistance, surface hardness, and longevity in the field or on the range.

Faxon’s use of 5R rifling helps reduce bullet deformation and fouling while increasing velocity and improving accuracy—making it ideal for both competitive shooters and precision rifle enthusiasts. The Nickel Teflon coated M4 feed ramp extension ensures smooth and reliable feeding, even under rapid-fire conditions.

This barrel is chambered in .223 Wylde, which allows safe and accurate use of both .223 Remington and 5.56 NATO ammunition. It’s configured with a rifle-length gas system for softer recoil and improved cycling. Faxon inspects each barrel individually for headspace using custom hardened gauges, ensuring optimal fit and function out of the box.

Just what is the Gunner profile?

The Gunner profile blends the rigidity of the Government profile through the chamber section with the weight savings of a Pencil profile forward of the gas block. This results in a well-balanced barrel that maintains heat resistance near the receiver while minimizing front-end weight. The design reduces shooter fatigue and improves handling without sacrificing accuracy or performance.
