Faxon Firearms Match 300 Blk 6" Nitride 416-R Stainless Qpq Barrel$170.20
Availability: In Stock
A 300 Blackout barrel built for shooters who want faster target acquisition and the low-fatigue ergonomics of a lightweight platform. The Faxon Firearms Match 300 Blackout 9" barrel pairs a 1:5 twist rate with the Gunner profile—a modern contour that splits the difference between rugged SOCOM durability and nimble pencil-profile weight savings. That twist rate is a full jump from the industry standard 1:7 and 1:8 you'll find elsewhere, which means tighter projectile stabilization and more consistent energy delivery, especially important when you're running subsonic loads or hunting with shorter barrels where velocity trades off for control.
Faxon manufactures this barrel in-house near Cincinnati from 416-R stainless steel and finishes it in hard black nitride—a surface that balances corrosion resistance with the traditional look most AR shooters prefer. The Match Series uses 5R rifling and a nickel-teflon-plated extension. Before it ships, every barrel is stress-relieved, air-gauge tested, Magnetic Particle Inspected, and verified for headspace with precision custom gauges. That's quality control that shows up in consistent accuracy and reliability you can count on whether you're hand-loading precision ammo or running suppressed duty rounds downrange.
The Gunner profile itself is the real win here if you shoot all day. By bringing the mass closer to your receiver, you reduce arm fatigue and muzzle rise without sacrificing the stiffness you need for accuracy. Whether you're training, hunting, or running a combat course, a lighter, more balanced rifle means you shoot better longer.

The faster 1:5 twist stabilizes projectiles more aggressively than common 1:7 and 1:8 rates, which means better accuracy and energy transfer downrange. That's especially valuable in a 9-inch barrel where velocity is already compressed, and even more so if you're running subsonic loads where bullet weight and stability matter.
Yes. The 9-inch length and 1:5 twist are optimized for subsonic performance, which is a core use case for 300 Blackout. The hard nitride finish also handles the additional heat and chemical exposure from a suppressor well.
The Gunner profile is a compromise between the stiffness of a heavy SOCOM profile and the light weight of a pencil profile. It brings balance closer to your receiver, which reduces fatigue during long shooting sessions and lessens muzzle movement without sacrificing the accuracy you need.
Every barrel is stress-relieved, air-gauge tested, Magnetic Particle Inspected for internal defects, fitted with an 11-degree target crown, and individually verified for headspace using precision custom-hardened gauges before final nitride finishing.
