Description
The 6.5 Grendel is one of the best long-range options you can run on an AR-15 platform, and Faxon's 16" Match Series Gunner barrel is a smart way to get there. It reaches out with high-BC projectiles, mild recoil, and solid energy retention past 600 yards, all from a lightweight setup that handles fast. Machined from 416R certified gun-barrel-quality stainless steel and finished inside and out with salt bath Nitride, it's built to hold accuracy and shrug off the elements over a long service life.
What the Gunner Profile Brings to a 6.5 Grendel Build
The Gunner contour is a blend of two proven profiles. From the extension to the gas block it mimics the Government taper for rigidity and heat resistance, then transitions to a pencil profile out front. That layout pulls weight toward the rear of the rifle, keeping the balance back near your body so you can shoot, train, or hunt all day without your support arm wearing out. It's a genuinely versatile choice whether you're chasing groups off a bipod or carrying it into the field.
Rifling, Gas System, and the Details That Matter
Faxon uses 5R button rifling here, a hybrid style with lands opposite grooves and softened angles that reduces jacket deformation. In practice that means better velocity consistency and a bore that cleans up easier. The 1:8 twist stabilizes the popular 90 to 123 grain 6.5 Grendel loads, and the mid-length gas system smooths out the recoil impulse for a more comfortable cycle. The chamber is a Type II 6.5 Grendel, so pair it with the correct Type II bolt and magazines for reliable feeding.
Faxon Match Series Quality You Can Count On
Every Match Series barrel is stress relieved, air-gauge tested, magnetic particle inspected, and headspace verified before it ships. The M4 extension is coated in Nickel Teflon for dry lubricity, corrosion resistance, and a tighter receiver fit that helps accuracy. It wears a threaded 5/8-24 muzzle and a polished 11-degree target crown, ready for your muzzle device of choice.

Frequently Asked Questions
What twist rate is the Faxon 16" 6.5 Grendel Gunner barrel?
This barrel has a 1:8 twist. That rate is dialed in for the popular 90 to 123 grain 6.5 Grendel projectiles, which covers the vast majority of factory and handloaded ammo. It gives you good stabilization across common bullet weights for both target work and hunting.
What bolt and magazines do I need for this barrel?
It uses a Type II 6.5 Grendel chamber, so you'll want a Type II 6.5 Grendel bolt and 6.5 Grendel magazines for proper feeding and function. Standard 5.56 bolts and mags won't work with this cartridge. Matching the correct components is the key to reliable cycling.
Is the Gunner profile good for accuracy or just weight savings?
It's built for both. The Gunner keeps a heavier Government-style contour from the extension to the gas block for rigidity and heat resistance, then thins out to a pencil profile up front to save weight. That combination is sub-MOA capable while still handling quickly, which is why it works so well for hunting and precision alike.
Does this barrel come threaded for a muzzle device?
Yes, the muzzle is threaded 5/8-24 TPI, which is the standard thread pitch for 6.5 Grendel and other larger AR-15 calibers. It also features a polished 11-degree target crown. That lets you install your preferred muzzle brake, flash hider, or suppressor mount right away.
