CMMG ZEROED B-Dapter SVB Brake .338 5/8x24 Muzzle Device

The CMMG ZEROED B-Dapter SVB Brake is a Plan B-pattern muzzle brake and quick-detach suppressor mount engineered for .338 caliber rifles, including 8.6 BLK and .300 BLK hosts, threaded 5/8x24. Part of CMMG's ZEROED accessories line, this dual-purpose device threads on as a brake and doubles as a mounting interface for the B-Dapter Plan B suppressor system, allowing a single HUB-compatible suppressor to be shared across multiple firearms.

The SVB Brake accepts any suppressor cut to the industry-standard 1.375x24 HUB thread pattern and features 13/16" wrench flats for straightforward installation and removal. It is also QD-compatible with CMMG's RBB muzzle devices, giving builders a flexible platform for switching between unsuppressed and suppressed shooting without changing muzzle devices.
