FAXON MATCH SERIES FLAME FLUTED® 16" 1:3T CARBINE-LENGTH 8.6 BLK AR10 BARREL
Faxon
Faxon Match Series Flame Fluted® AR-10 Barrel — 16" 8.6 Blackout (1:3 Twist, Carbine Gas)
416-R stainless • 5R button rifled • Salt bath nitride (QPQ) inside & out • Nickel Teflon coated DPMS LR-308 compatible extension • MPI inspected • Recessed 11° target crown • Carbine-length gas • .875" gas block journal • M18x1.5 RH muzzle
The Faxon Match Series Flame Fluted® 16" 8.6 Blackout (8.6 BLK) AR-10 barrel is built for shooters who want match-ready fundamentals with the durability to run hard—especially in modern suppressed 8.6 BLK setups. You get a fast 1:3 twist, a balanced carbine-length gas system, and the signature Flame Fluting® profile for a proven stiffness-to-weight feel.
Match Series barrels start with 416-R stainless steel and 5R rifling (button rifled). After rigorous testing, the barrels are treated with salt bath nitride (QPQ) inside and out to improve corrosion resistance, reduce fouling, and support long service life. The Nickel Teflon coated extension delivers excellent dry lubricity and corrosion resistance at the interface, supporting smooth cycling and consistent lockup. A recessed 11° target crown protects the muzzle, and every barrel is MPI inspected.
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 bullet jacket deformation and can improve consistency and ease of 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 helps smooth cycling and supports 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 barrel profile that’s lighter than a comparable heavy contour, maintains a performance-focused feel, and carries the unmistakable Match Series look.
Ideal Use Cases
- Suppressed 8.6 BLK AR-10 builds: Durable QPQ finish and modern muzzle interface for serious use (verify mount alignment).
- Heavy-for-caliber 8.6 BLK projectiles: 1:3 twist optimized around the projectile weights common to 8.6 Blackout.
- Competition, training, and high round counts: QPQ nitride inside/out supports longevity and easier maintenance.
- Builders who want signature performance styling: Flame Fluting® delivers a distinctive look with functional intent.

Awesome barrel
I received my 16 inch 8.6 blackout barrel in just a few days after buying it. I added a gas tube and gas block to the order as well. Installation was a breeze. It looks amazing. I had already bought some 300gr SMK’s and dies before hand so I had ammo ready to go when the barrel showed up. Perfect reliability. Totally accurate and silent using just a Dead Air Wolfman 9mm silencer that I already had. I’m completely happy with the performance and looks of this barrel. Coincidentally I’m receiving some expanding subsonic 350gr and 220gr super expanding bullets from Maker today that I’m super excited to load and try out. What a rifle! I couldn’t be any happier with this purchase.
