Faxon 6.5 Grendel 18″ Heavy Fluted 5R Match Series Barrel

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

The Faxon 6.5 Grendel 18″ Heavy Fluted 5R Match Series Barrel is a premium offering for shooters who demand long-range accuracy, durability, and exceptional craftsmanship. Machined entirely in-house from 416R stainless steel, this barrel starts life as match-grade bar-stock and is carefully stress-relieved and button rifled to ensure consistent performance shot after shot.

This barrel features 5R rifling—a proven design that reduces jacket deformation and fouling while improving accuracy and barrel life. Combined with a precision 11-degree target crown and MPI inspection, each barrel leaves the factory fully vetted for headspace using hardened custom gauges to ensure reliable lockup and performance. Whether you’re shooting for groups or hunting at extended ranges, this barrel is built to deliver.

The heavy profile is complemented by aggressive straight fluting, which shaves off nearly 16 ounces compared to the non-fluted equivalent without sacrificing stiffness. The fluting not only lightens the barrel but also improves heat dissipation and rigidity, helping you stay on target during long shot strings. The Faxon 6.5 Grendel 18″ barrel is finished in a QPQ Nitride coating for superior corrosion resistance and features a Nickel Teflon coated M4 feed ramp extension for enhanced feeding reliability.

This model is configured with a mid-length gas system and is compatible with 0.75″ gas blocks, offering optimal recoil control and reliable cycling across a wide range of ammunition. It’s an ideal upgrade for serious Grendel shooters looking to step up their performance without compromise.
