The Faxon Firearms Match Series AR10 barrel (brand part no. 10B810R20SHQ5RNP3) is a 20-inch .308 Winchester barrel built for accuracy-focused AR10 builds, machined from 416-R stainless with 5R rifling on a 1:10 twist. Faxon nitride treats the barrel inside and out for corrosion resistance and long service life, then finishes the exterior in matte black with a distinctive spiral fluted profile that trims weight while adding visual flair. A recessed target crown protects the muzzle and supports consistent accuracy, and the threaded muzzle accepts standard .308-caliber muzzle devices. Built with a DPMS LR-308 compatible extension and a rifle-length gas system, this barrel suits precision and general-purpose AR10 rifles on the DPMS pattern.
