Description
CMMG’s 300 Blackout barrel sub-assembly gives you a quality 4140 chromoly steel tube with a proven 1:7″ twist rate that handles both subsonic and supersonic ammunition without compromise. The 8″ pistol-length configuration works great in compact AR builds, and the threaded 5/8″-24 muzzle is ready for suppressors or flash hiders. You’re getting a nitride-finished barrel that resists corrosion and won’t let you down whether you’re zeroing in on hogs at 50 yards or running drills at the range. If you’re building a short, handy AR pistol chambered in 300 Blackout, this sub-assembly takes the guesswork out of barrel selection.
