CMMG ZEROED RBB Brake 9mm 1/2x28 B-Dapter Suppressor Mount
The CMMG ZEROED RBB Brake is a premium muzzle brake and suppressor mounting solution engineered for 9mm firearms with a 1/2x28 threaded barrel. Designed as part of CMMG's B-Dapter (Plan B compatible) mounting system, this muzzle device provides effective recoil and muzzle rise reduction when fired unsuppressed while serving as a quick and secure mounting interface for compatible suppressors.
Precision-machined from high-strength steel with a durable nitride finish, the ZEROED RBB Brake features a radial port design that requires no timing during installation. The tapered mounting interface helps create a secure seal that minimizes carbon buildup while providing reliable suppressor alignment for demanding range, competition, and tactical applications.
