Product Description

The Faxon Firearms Big Gunner .308 Winchester 18-inch barrel is built to deliver a balanced blend of rigidity and handling for AR10/DPMS LR-308 pattern builds. Featuring Faxon’s Big Gunner contour (medium taper behind the gas block with a slimmer forward taper), this barrel helps reduce front-end weight while maintaining the stability needed for high rates of fire and suppressor-host use. It’s manufactured from duty-grade 4150 CMV steel and finished with salt bath nitride (QPQ) inside and out for excellent wear and corrosion resistance. A rifle-length gas system promotes a smooth recoil impulse, while the 11° target crown and 1:10 twist are optimized for consistent .308 Win performance.

Product Highlights

  • Big Gunner (Gunner) profile balances strength behind the gas block with reduced forward weight for faster handling.
  • 4150 CMV steel construction with salt bath nitride (QPQ) inside and out for long-lasting corrosion and wear resistance.
  • Rifle-length gas system on an 18-inch .308 barrel for a smooth recoil impulse and reliable cycling.
  • DPMS / LR-308 compatible extension with 5/8x24 muzzle threads for common .30-cal muzzle devices and suppressor mounts.
  • Quality-focused build features include MPI inspection and an 11° non-recessed target crown for consistent shot release.
