The AXIS Series 7.5" Gunner 300 BLK is purpose-built for compact, accurate, and reliable blackout builds. A honed & lapped 416R stainless bore paired with 5R rifling and a fast 1:5 twist maximizes projectile stability—especially with heavy subsonic loads—while maintaining excellent performance with supersonics.

Faxon’s Gunner profile blends Government strength with Pencil-like agility to keep weight off the muzzle for quicker transitions and reduced shooter fatigue. Finished in a clean bead-blast, this AXIS barrel is made and quality-checked in-house in Greater Cincinnati, Ohio.
