Product Description The CMMG ZEROED B-Dapter Radial Bleed Brake (RBB) is a precision-engineered muzzle device designed for shooters who want a set-and-forget suppressor quick-detach solution. Threaded 1/2x28 and rated for cartridges up to and including 9mm/.36 caliber, the RBB Brake is a core component of the CMMG B Dapter (Plan B compatible) suppressor mounting system. Its radial port design effectively vents propellant gases when shooting unsuppressed, and critically, the brake requires no timing during installation, eliminating a common point of frustration. The B Dapter system relies on precision machined threads and a taper seal rather than springs or detents, meaning there are no small parts to seize, bind, or break. Simply screw a B Dapter-equipped suppressor onto the installed RBB until it seats snugly. The mating machined tapers seal together to prevent carbon fouling and provide enough resistance to require more force to remove than to install, keeping the suppressor securely in place. Each unit ships with an RBB Brake Rocksett packet to assist with installation. Product Highlights No-Timing Installation: Radial port design eliminates the need to time the muzzle device during installation, saving setup time and reducing user error. B Dapter Suppressor Mounting System: Compatible with Plan B suppressor mounts, utilizing a threaded taper seal for a carbon-resistant, rattle-free suppressor attachment with no springs or detents. Effective Gas Venting: Radial bleed ports efficiently redirect and vent gases when shooting unsuppressed, maintaining consistent performance. 1/2x28 Thread Pitch: Fits a wide range of 9mm/.36 caliber and smaller firearms with the standard 1/2x28 threaded muzzle. Includes Rocksett Packet: Ships with a Rocksett adhesive packet for a secure, heat-resistant installation without crush washers.
