The Faxon Match Series Flame Fluted® 12" 8.6 Blackout (8.6 BLK) AR-10 barrel is built for compact, high-performance 8.6 BLK rifles and pistols where maneuverability, suppressor use, and heavy-projectile stability are priorities. With a fast 1:3 twist and pistol-length gas system, it’s tuned for modern 8.6 Blackout setups in the AR-10 / LR-308 pattern.

Match Series barrels start with 416-R stainless steel and 5R rifling (button rifled). After rigorous testing, the barrel is treated with salt bath nitride (QPQ) inside and out to improve corrosion resistance, reduce fouling, and support long service life—especially in hard-use and suppressed shooting. The Nickel Teflon-coated extension provides excellent dry lubricity and corrosion resistance at the interface, supporting smooth cycling and consistent lockup. Each barrel is MPI inspected and finished with a recessed 11° target crown.

Proudly American-made by a family-owned manufacturer in Greater Cincinnati, Ohio. Learn more about the 8.6 BLK cartridge: click here.

Why These Match Series Features Matter

• 416-R Stainless + 5R Rifling: Match-grade stainless with 5R geometry helps reduce sharp engraving and can support consistency and easier cleaning.
• QPQ Nitride Inside & Out: Hard, corrosion-resistant surface that helps reduce fouling and supports longer barrel life in hard-use or suppressed shooting.
• Nickel Teflon Extension: Dry lubricity and corrosion resistance at the extension interface supports smooth cycling and consistent lockup.
• Recessed 11° Target Crown: Protects the critical muzzle edge that influences accuracy.
• MPI Inspected: Adds confidence that each barrel meets Faxon’s quality standards.

Flame Fluting®: Patented Variable-Depth Fluting

Flame Fluting® is Faxon’s signature variable-depth fluting approach developed by our founder and president, Robert T. Faxon. Rather than uniform straight flutes, Flame Fluting uses changing flute depth/geometry along the barrel to reduce weight while promoting a strong stiffness-to-weight balance and adding external surface area for improved cooling.

In short: you get a compact 8.6 BLK barrel that’s optimized for handling while maintaining a performance-focused feel and distinctive Match Series style.

Ideal Use Cases

• Suppressed 8.6 BLK AR-10 builds: QPQ nitride inside/out helps reduce corrosion and fouling; confirm mount alignment and system tuning.
• Compact 12" setups: Pistol gas and short length for maneuverability without sacrificing capability.
• Heavy-for-caliber 8.6 BLK projectiles: 1:3 twist optimized around the projectile weights common to 8.6 Blackout.
• Duty, training, and competition: Match-grade materials and finishes with durability-focused execution.

Specifications
