ZEROED RBB Brake, 1/2"-28, 9mm
For a suppressor QD muzzle device you can set and forget, the ZEROED RBB Brake is the perfect choice. The radial port design effectively vents gases when shooting unsuppressed and doesn't require timing during installation. Threaded 1/2x28 for cartridges up to and including 9mm/.36 caliber, the RBB is part of the CMMG B Dapter (Plan B compatible) suppressor mounting system, making it easy for suppressor hosting on any rifle or PDW.
The B Dapter/Plan B system utilizes threads and a taper seal, no moving springs or detents to get stuck or break. With the B Dapter mount installed on your suppressor and RBB muzzle device on your firearm, simply screw the suppressor onto the gun until it seats and make sure it is snug. No need to crank down on it as the machined tapers between the mount and muzzle device seal together preventing carbon fouling, and secure against each other requiring more force to remove than install.
Includes:
- RBB Brake
- Rocksett Packet
Note: To prevent baffle strikes, do NOT use crush washers when installing muzzle device.
