ZEROED RBB Brake, M12x1 LH, PS90/P90

If you own a PS90* and want to give it the B Dapter/Plan B suppressor mounting system treatment without any adapters, this is the brake for you! This CMMG RBB Brake is threaded M12x1 Left Hand specifically for PS90* firearms, allowing you quickly attach or remove your favorite suppressor with a B Dapter/Plan B-pattern mount. NOTE: Brake must be used with an SBR'd PS90* equipped with a CMMG 10.4" barrel, will NOT work with factory rifle length barrels.

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.
