Description
The Proof Research AR-Style Barrel is a drop-in replacement barrel chambered in the 6mm ARC cartridge and built for the AR-platform. Part of Proof Research’s Traditional series, this barrel is machined from stainless steel with a stainless finish for corrosion resistance and long service life.
This 16″ barrel is cut with a 1:7.5″ twist rate and uses a rifle length gas system with a .750″ gas journal diameter. The muzzle is threaded so the end user can install a flash hider, muzzle brake, or suppressor to match the build. The barrel ships with no sights installed, leaving the top of the platform free for an optics-ready handguard and the shooter’s preferred optic.
Built around Proof Research’s Traditional-series profile and quality-controlled machining, the 128664 6mm ARC barrel is a solid foundation for a custom AR-platform rifle project.
