Product Description

Factory pre-pinned .750" gas block included for rock-solid reliability and fast installs.

The Faxon 10.5" 300 Blackout Gunner Barrel with Pinned Gas Block removes the hardest part of short-barrel builds: correctly pinning the gas block. We pre-notch the journal, drill the block, and include the pin—so your gas system won’t shift or loosen under fire.

Built from 4150 CMV steel with a nitride finish, this Gunner profile blends Gov’t durability with Pencil-like weight savings for superb handling. Pistol-length gas optimizes function with both supers and subs (especially suppressed), while 1:8 twist stabilizes a wide range of 300 BLK projectiles.

Features

  • Factory-pinned .750" gas block: Pre-drilled and aligned for maximum security and easy installation.
  • Gunner profile balance: Gov’t strength with Pencil weight for faster transitions and reduced fatigue.
  • Pistol-length gas: Reliable cycling with subsonic and supersonic 300 BLK, ideal for suppressed builds.
  • Duty-ready construction: 4150 CMV, button-rifled 1:8, and QPQ nitride inside & out.
  • Precision QC: Stress relieved, air-gauge tested, MPI-inspected, and headspace verified in-house.
