Product Summary
The CMMG 300 AAC Blackout Barrel is a high-quality 12.5-inch barrel designed for carbine-length gas systems. Constructed from Chrome Moly Steel, it features a 1:7″ twist rate and a durable salt bath nitride finish for superior corrosion and carbon resistance. The 5/8″-24 threaded muzzle allows for easy attachment of suppressors, flash hiders, or muzzle brakes. This barrel is versatile enough to handle both subsonic and supersonic loads in suppressed or unsuppressed configurations. It offers the benefits of a slick bore without the accuracy issues often caused by traditional chrome lining.
