Faxon Firearms Match 6.5 Grendel 20'' 1-8 Twist Heavy Contour Bbl Nitride

The Faxon Firearms Match 6.5 Grendel 20" 1-8 Twist Heavy Contour Barrel delivers match-grade accuracy in a purpose-built platform for precision rifle builds. Built around 5R button rifling—a design that offsets lands and grooves to minimize bullet distortion as it travels down the bore—this barrel maximizes the inherent accuracy potential of the 6.5 Grendel cartridge. The 1-8 twist rate stabilizes a broad range of bullet weights, making it equally at home with lighter varmint rounds or heavier match loads. At 20 inches, this configuration pairs with a rifle-length gas tube for smooth, reliable cycling in AR-platform builds.

Faxon manufactures this barrel from high-grade 416R stainless steel at their Cincinnati, Ohio facility and applies nitride coating inside and out—a finish that provides genuine corrosion and wear resistance without adding bulk. The heavy contour profile supports consistent harmonic performance and thermal stability under sustained fire, critical for target and competition shooting. The straight flutes deliver that classic match rifle aesthetic while keeping weight reasonable for a precision build.

The muzzle comes crowned with an 11° target profile and threaded 5/8"-24 to accept suppressors, brakes, flash hiders, or other muzzle devices. Like every Faxon barrel, this one undergoes rigorous quality-control testing before it ships, so you can trust it to hold the accuracy you've dialed in.

Frequently Asked Questions

What gas tube length does this 20" barrel require?

This 20" barrel is configured with a rifle-length gas port, so it pairs with a rifle-length gas tube in AR-platform builds.

Will this barrel stabilize heavy 6.5 Grendel bullets?

Yes. The 1-8 twist rate is rated to stabilize a wide range of bullet weights across the 6.5 Grendel spectrum, from lighter varmint loads to heavier match ammunition.

Can I attach a suppressor to this barrel?

Yes. The muzzle is threaded 5/8"-24 and is suppressor-ready, as well as compatible with muzzle brakes, flash hiders, and other standard devices.

What makes 5R rifling different from standard rifling?

5R button rifling offsets the lands and grooves instead of placing them directly opposite each other. This design prevents bullet distortion as it travels through the bore, allowing the barrel to deliver tighter groups and more consistent accuracy.
