Durable & Reliable 18 Inch Heavy Fluted Barrel For 6.5 Grendel Rifles

The Faxon Firearms Match Series 18 Inch Heavy Fluted 6.5 Grendel Barrel is an outstanding upgrade to achieve long-range accuracy and long-term durability, while providing a lightened profile. It features opposite grooves and reduced sharp angles that reduce jacket deformation increasing velocity and easy cleaning.

It is made of durable 416-R Steel and coated with Salt Bath Nitride inside and out providing added resistance to corrosion and less friction down the bore that effectively prolongs the barrel’s reliability.

Unique Heavy Fluted Design To Dissipate Heat

The Faxon Firearms Match Series 18 Inch Heavy Fluted 6.5 Grendel Barrel features a unique heavy fluted design that not only looks great but also dissipates barrel heat to resist distortion to allow the shooter to take full advantage of the potential of the 6.5 Grendel caliber.

It also allows better projectile velocity and makes for an easier-to-clean bore than a traditional rifling pattern. These barrels are manufactured 100% in-house and go through rigorous testing to ensure durability and optimum accuracy.

Note: This barrel is 6.5 Grendel Type 2.  Be sure to use a compatible 6.5 Grendel Type 2 BCG.

Great Barrel

Bought the 18" Faxon fluted Match grade barrel to complete a 6.5 Grendel build. The gun turned out extremely light and even more accurate. Love it!
