Faxon Match Series 7.5″ Gunner .300 BLK 416R SS QPQ Nitride 5R Pistol-Length Barrel
The Faxon Match Series 7.5″ Gunner 300 BLK 416R SS QPQ Nitride 5R Pistol-Length Barrel is the ultimate choice for AR-15 builders who prioritize balance, maneuverability, and high performance in a compact form factor. Precision machined from 416R stainless steel, this barrel features Faxon’s signature Gunner profile, which blends the robustness of a government contour with the weight savings of a pencil profile. This combination brings the rifle’s center of gravity closer to the shooter, reducing fatigue and improving handling during extended range time or tactical use.
Optimized for the 300 Blackout cartridge, this barrel features 5R button rifling and a fast 1:5 twist rate. This twist is ideal for stabilizing a wide range of bullet weights, hefty subsonic rounds, delivering impressive accuracy and consistent energy transfer. The rifling design minimizes jacket deformation and fouling, thereby improving accuracy over time and simplifying cleaning.
Inside and out, the barrel is treated with a salt bath nitride finish for excellent corrosion resistance and surface hardness, making it a durable choice for field or home defense use. The M4 barrel extension is Nickel Teflon-coated to provide added lubricity and corrosion resistance while ensuring a tight, precise fit with the upper receiver.
The 5/8×24 TPI muzzle threading offers compatibility with most suppressors and muzzle devices, while the recessed 11-degree target crown supports consistent gas release and tight groupings. The .750″ gas block journal and 1.9″ journal length provide flexibility for various gas block configurations, and the pistol-length gas system ensures reliable cycling in short-barreled or suppressed builds.
Weighing just 0.89 lbs, this barrel strikes the perfect balance between strength and agility. Each barrel undergoes magnetic particle inspection to ensure flawless structural integrity and performance.
