The Faxon Match Series Heavy Fluted 18" .308 Win AR10 barrel is designed for shooters who want a compact, precision-forward .308 AR10 barrel with confident thermal performance and repeatable consistency. With rifle-length gas in an 18-inch format, it’s a great fit for practical precision builds that value smooth cycling and balanced handling.
Match Series barrels begin with 416-R stainless steel and 5R button rifling. 5R geometry is designed to reduce jacket deformation and support consistent performance while remaining easy to maintain. After rigorous testing, the barrel receives salt bath nitride (QPQ) treatment inside and out to improve wear resistance, corrosion protection, and service life.
The heavy fluted profile increases surface area for heat management while preserving practical rigidity for repeatable precision. A Nickel Teflon coated DPMS/LR-308 compatible extension adds dry lubricity and corrosion resistance at the receiver interface. Finished with a recessed 11-degree target crown and MPI inspection, this barrel is proudly American-made by a family-owned manufacturer in Greater Cincinnati, Ohio.
