PS90 Muzzle Brake with Integrated Plan B Adapter Compatibility
The CMMG ZEROED RBB Brake is a compact PS90 muzzle brake that also serves as a Plan B adapter for compatible suppressor mounting systems. Designed for use with 10.4″ PS90 short barrels, it features M12 x 1.0 left-hand threads and provides a streamlined solution for both muzzle control and suppressor attachment.
By combining a muzzle brake and Plan B adapter into a single component, the ZEROED RBB Brake eliminates the need for thread adapters, thread extensions, or component stacking. The result is a lighter, more streamlined mounting solution with fewer potential points of failure. With only the barrel, muzzle device, and suppressor accessory in the mounting chain, users benefit from reduced weight, a more compact overall package, and improved alignment compared to multi-component mounting setups.
