CMMG ZEROED B-Dapter SVB Brake 5.56x45mm NATO 1/2x28

The CMMG ZEROED B-Dapter SVB Brake is a muzzle device and suppressor mount platform designed for firearms chambered in 5.56x45mm NATO. Part of CMMG's ZEROED accessory line, this device threads onto barrels with a 1/2x28 pitch and integrates the brand's B-Dapter muzzle device and suppressor mount system into a single component.

The compact body is machined with 13/16" wrench flats that allow straightforward installation or removal using a standard crowfoot or socket wrench, making it a simple upgrade for any 5.56mm barrel with a standard 1/2x28 thread pattern.

Beyond its role as a stand-alone muzzle brake, the B-Dapter interface serves as the mounting point for compatible CMMG suppressor mounting hardware, giving shooters a single-thread solution for both bare-muzzle and suppressed configurations. Installation requires a barrel with a standard 1/2x28 thread pattern.
