FAXON MATCH SERIES HEAVY FLUTED 18" RIFLE-LENGTH .308 WIN AR10 BARREL
Faxon Match Series — 18" Heavy Fluted .308 Win AR-10 Barrel
416R Stainless • 5R Button Rifled • Heavy Fluted • Salt Bath Nitride (I/O) • Nickel Teflon Extension • 5/8x24 Threads • Rifle-Length Gas
The Faxon Match Series 18" Heavy Fluted .308 Win Barrel elevates accuracy, thermal performance, and durability for AR-10 builds that demand match-grade results. Manufactured 100% in-house in Cincinnati, Ohio, this barrel combines 416R stainless, 5R button rifling, and a heavy fluted contour for excellent rigidity and cooling without unnecessary weight.
After rigorous inspection, each barrel is Salt Bath Nitride treated inside and out to harden the bore and resist corrosion. The Nickel Teflon–coated DPMS/LR-308 extension adds dry lubricity and tightens the receiver fit to enhance accuracy and reliability.
Every Match Series barrel is stress-relieved, air-gauge tested, magnetic particle inspected, and individually headspaced with precision gauges for safe, repeatable performance.

- Rifle-Length Gas: Smooth recoil impulse and reliable cycling for 18" AR-10 setups.

Specifications
Important Product Note
Match Series barrels are manufactured to tight tolerances. Verify proper torque, receiver fit, and headspace when installing on DPMS-pattern receivers. Faxon recommends professional installation. Improper installation or incompatible parts may cause damage or void warranty.
Frequently Asked Questions
What advantages does 5R rifling provide?
5R rifling places lands opposite grooves and reduces sharp angles, minimizing jacket deformation, improving velocity consistency, and making the bore easier to clean.
Why choose a heavy fluted contour?
You get the stiffness of a heavier barrel with improved cooling and reduced weight versus a full bull contour—ideal for precision and sustained strings of fire.
Is this barrel suppressor-ready?
Yes. Standard 5/8x24 threading fits most .30-cal muzzle devices and suppressors. Always verify suppressor caliber rating.

Faxon 308
This barrel is going in an AR10 build with SLR adj gas block and tube, Live Free Armory AR308 upper lower and HG. A Geissle two stage puts the quality of this rifle on par with any of the high end AR308s

Fluted barrel
This barrel was my first purchase ever from Faxon, to go along with my first ever build on my FIRST ever AR10. The fit and finish are superb. I knew it was going to be heavier than any of my M4s, and I was interested in how all of this was going to fit together. When I took it to the range to break in, dial in the adjustable gas block and zero my scope, I couldn't believe my astonishment at the groupings at just 100m. All sub MOA. ALL... I'd had tight groupings before with my M4 and while in the Army, but this...holy. crap. I had my wife get behind it and familiarize herself with it. Even SHE had the same sub groupings AND her zero is the same as mine! Since then, I've purchased a second barrel for her own .308/battle rifle build. We haven't had the chance to take it out yet to get it dialed in - but I am REALLY looking forward to experiencing the same performance Faxon's barrels have to offer!! The Faxon company has won me for life for all my builds!

Love this barrel
After doing a lot of research, I found this company. This was the first of two barrels that I have purchased from Faxon. After all these years, I finally built my very first AR10. I wanted to build a rifle that was very accurate, and in this platform for quick follow up shots. I am shooting right at one MOA (random ammo) with this barrel and I am extremely happy! I'm currently working up my own load data for this rifle to ring out every bit of accuracy that I can. The fit and finish were fantastic. And while I love a great heavy barrel for precision work, I ordered a match series 16 inch .223 Wylde barrel in the gunner profile for a friend building her first carbine. The accuracy of that barrel is outstanding as well. While I have tried many other barrels for different firearms I have built over the years, I will now stick with Faxon for any future builds.
