Faxon Match Series 7.5″ Gunner .300 Blackout 416R SS Matte 5R Pistol‑Length Barrel

The Faxon Match Series 7.5″ Gunner .300 Blackout pistol‑length barrel is precision‑crafted for ultra‑compact AR builds demanding match‑grade accuracy in a small package. Machined from 416R stainless steel and button rifled with a 5R profile, this barrel is honed and lapped for a smooth bore finish. The robust Gunner contour at the chamber maximizes rigidity where it’s needed most, then tapers to a slender profile to save weight and improve handling—ideal for close‑quarters engagement or PDW applications.

Chambered in .300 Blackout with a fast 1:5 twist rate, the barrel stabilizes both heavy subsonic rounds and supersonic loads, enabling versatility from suppressed target work to quick‑handling defensive scenarios. Its pistol‑length gas system ensures reliable cycling without the bulk of longer gas setups, and the .750″ gas‑block journal provides a stable mounting surface. Finished with a bead‑blast exterior, it resists corrosion while maintaining a low‑glare appearance.

The muzzle is threaded 5/8×24 TPI for easy attachment of brakes, compensators, or suppressors, and the M4 extension guarantees rock‑solid lockup with standard Mil‑Spec uppers. Weighing just 0.89 lbs and measuring 7.5″ overall, this barrel keeps the front end light for rapid transitions without sacrificing the stiffness needed for tight groups. Faxon performs magnetic particle inspection (MPI) and air‑gauge testing on every barrel to verify straightness and dimensional integrity.

Whether you’re building a compact competition rig, a dedicated suppressed pistol, or a versatile patrol weapon, the 7.5″ Gunner .300 Blackout barrel delivers unmatched consistency and durability.
