Faxon® Match Series 8″ Gunner Barrel | 8.6 Blackout (8.6 BLK) | Pistol Gas
Compact 8.6 Blackout Performance with Match-Grade Precision
The Faxon® Match Series 8″ Gunner Barrel chambered in 8.6 Blackout (8.6 BLK) delivers precision performance in an ultra-compact large-frame AR platform. Featuring a 1:6 twist rate and pistol-length gas system, this barrel is optimized for modern suppressed and subsonic applications while maintaining reliable function across a wide range of ammunition.
416-R Stainless Steel with 5R Rifling
Machined from premium 416-R stainless steel, this Match Series barrel is built for accuracy, corrosion resistance, and long-term consistency. The 5R button rifling reduces bullet deformation and fouling, improving velocity consistency and simplifying cleaning—ideal for both suppressed and high-volume shooting environments.
QPQ Nitride Finish and NP3-Coated Extension
The barrel is finished with salt bath nitride (QPQ) inside and out to enhance surface hardness, corrosion resistance, and wear durability. A Nickel-Teflon (NP3) coated DPMS/LR-308 pattern extension improves lubricity, promotes smooth feeding, and ensures consistent lockup under demanding conditions.
Optimized Gas System and Compact Gunner Profile
Featuring a pistol-length gas system and Faxon’s Gunner profile, this barrel balances maneuverability and structural integrity. The profile reinforces the chamber area while reducing forward weight, delivering improved handling without sacrificing rigidity during sustained fire.
Precision Machining and Quality Assurance
Each barrel is Magnetic Particle Inspected (MPI) for quality assurance and features a recessed 11° target crown to protect the muzzle and maintain accuracy. The .875″ gas block journal and extended journal length provide a stable interface for gas system components.
