The CMMG Zeroed B-Dapter SVB Brake 338 5/8x24 is a purpose-built muzzle brake designed to give larger bore rifles noticeably softer recoil and flatter tracking. Machined with generous side ports and a sleek profile, it works seamlessly with CMMG’s B Dapter and compatible Plan B–pattern suppressor mounts while still performing as an effective standalone brake.

This model is threaded 5/8x24 for .338 caliber or smaller barrels and features 13/16" wrench flats for straightforward installation and removal. Ideal for precision rifle shooters and anyone running heavier cartridges, it helps you stay on target for faster follow-up shots and better impact observation. With its durable nitride finish and smart taper-sealed interface, it reflects CMMG’s focus on practical innovation and dependable performance.
