Faxon Match Series 6mm ARC 16in Gunner Barrel 1:7.5

The Faxon Firearms Match Series barrel in 6mm ARC is a 16-inch Gunner-contour barrel designed for AR-15 platforms where precision and manageable weight are priorities. Manufactured from 416-R stainless steel and finished with a salt-bath nitride treatment, the barrel combines corrosion resistance with a treated bore for extended life. It uses 5R button rifling with a 1:7.5 twist rate and features a mid-length gas system and 5/8-24 muzzle threads. The Gunner contour blends the durability of a government profile with the weight savings of a pencil profile for versatile field and target use.
