Faxon 6.5 Grendel 18″ Gunner 5R Match Series Barrel

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

The Faxon 6.5 Grendel 18″ Gunner 5R Match Series Barrel delivers exceptional performance in a lightweight, precision-crafted platform. Machined from high-grade 416R Stainless Steel, this barrel is part of Faxon’s Match Series line, designed for shooters who demand pinpoint accuracy without sacrificing maneuverability. Every barrel is fully stress-relieved, button rifled, and inspected for headspace using precision custom gauges.

Faxon’s use of 5R rifling helps reduce jacket deformation and fouling, resulting in higher velocities and more consistent accuracy. The 11-degree target crown at the muzzle enhances bullet stability as it leaves the barrel, contributing to improved downrange performance. The barrel also features a durable QPQ Nitride finish for corrosion and wear resistance, as well as a Nickel Teflon coated M4 feed ramp extension for smoother feeding under high-volume fire.

What truly sets this barrel apart is its use of the Gunner profile—a hybrid design that blends the taper of a Government profile near the receiver with a lighter pencil contour toward the muzzle. This strategic weight distribution maintains accuracy and heat resistance while reducing front-end mass for improved handling. The result is a perfectly balanced barrel for dynamic shooting scenarios.

Configured with a mid-length gas system and a 0.75″ gas block journal, this 6.5 Grendel barrel is ready for smooth, reliable cycling and optimized recoil control. Whether you’re building a precision DMR or a hunting rifle, the Faxon 6.5 Grendel 18″ Gunner Barrel provides match-grade performance in a streamlined package.
