The CMMG Zeroed B-Dapter SVB Brake 5.56 1/2x28 is a purpose-built muzzle brake designed to pair effective recoil reduction with reliable suppressor mounting. Machined with 1/2x28 threads for 5.56mm and smaller .22-caliber bores, it integrates into CMMG’s B Dapter and Plan B pattern systems, giving shooters a single device that works well both suppressed and unsuppressed. The compact, nitride-finished body features 13/16" wrench flats for straightforward installation and removal.

This brake is ideal for AR-15 style rifles and lightweight carbines where controlling muzzle rise helps maintain a clean sight picture during rapid strings of fire. When used with a compatible suppressor and B Dapter mount, the taper-sealed interface keeps carbon fouling in check and secures the can without relying on springs or detents. Whether you are focused on range practice, training, or competition, the Zeroed B-Dapter SVB Brake reflects CMMG’s attention to detail and commitment to practical innovation.
