Description

416R Stainless • Honed & Lapped • 5R Rifling • 1:5 Twist • Gunner Profile • Bead-Blast Finish

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.

Key Benefits

  • Honed & Lapped Bore: Smoother interior finish for reduced fouling and repeatable precision.
  • 1:5 Twist + 5R Rifling: Excellent stabilization for heavy subsonic bullets; broad compatibility with supersonics.

  • Gunner Profile: Lightweight forward balance without sacrificing strength.
  • In-House QC: Stress relieved, air-gauge tested, MPI inspected, and headspace verified.
