Product Description

The Faxon Firearms Duty Series Gunner Profile 10.5" .300 Blackout (300 BLK) AR-15 barrel is built for compact, hard-use builds that demand reliable cycling and balanced handling. Machined from rugged 4150 CMV steel and finished with salt bath nitride inside and out, this barrel is engineered for corrosion resistance, easy maintenance, and long service life. The Gunner profile blends strength where it matters with reduced forward weight for quick maneuverability, while the pistol-length gas system is optimized for .300 BLK performance with both subsonic and supersonic loads. Each barrel is button rifled with a 1:8 twist and subjected to stringent quality control including stress relief, air-gauge testing, magnetic particle inspection (MPI), and headspace verification.

Product Highlights

  • Duty Series Gunner profile balances Government-contour strength with pencil-profile weight savings for fast handling.
  • Pistol-length gas system optimized for .300 Blackout reliability in short AR-15 platforms (suppressed or unsuppressed).
  • 4150 CMV mil-spec steel construction for durability and heat resistance under sustained firing.
  • Salt bath nitride finish (inside & out) enhances corrosion resistance and wear life.
  • Quality checked: stress relieved, air-gauge tested, MPI inspected, and headspace verified.
