Faxon Match Series 6″ Gunner .300 Blackout 416R SS QPQ Nitride 5R Pistol-Length Barrel
The Faxon Match Series 6″ Gunner .300 Blackout 416R SS QPQ Nitride 5R Pistol-Length Barrel delivers top-tier performance in an ultra-compact package designed specifically for AR-15 builders looking to optimize short-barreled or suppressed setups. Precision machined from 416R stainless steel, this barrel features Faxon’s Gunner profile, blending the durability of a government contour with the weight reduction and responsiveness of a pencil-style profile. The result is a highly maneuverable barrel that keeps the front end light, improving control and reducing shooter fatigue during extended use.
Chambered in .300 Blackout, this barrel accommodates both subsonic and supersonic loads with ease. The 5R button rifling is paired with a fast 1:5 twist rate, offering superior stability for heavy projectiles and helping maintain accuracy in suppressed applications. This rifling design also reduces fouling and deformation of the projectile, extending the life of both the barrel and your ammunition. A salt bath nitride treatment coats both the interior and exterior surfaces, significantly enhancing corrosion resistance and wear protection.
The barrel includes a pistol-length gas system optimized for reliable cycling in compact builds, and a 5/8×24 threaded muzzle allows for direct installation of suppressors or muzzle devices. The M4 barrel extension is coated with Nickel Teflon, adding dry lubricity while creating a tight, consistent lockup with your upper receiver. With a gas block diameter of .750″ and a journal length of 1.03″, it accepts standard low-profile gas blocks and provides a wide range of compatibility.
Weighing only 0.74 lbs, this barrel offers a perfect balance of strength and agility. The recessed 11-degree target crown enhances downrange accuracy by ensuring clean gas exit at the muzzle. Each barrel is magnetic particle inspected to verify structural integrity, ensuring dependable performance.
