CMMG Zeroed SVD Muzzle Brake, 1/2-28, Black

The CMMG Zeroed SVD Muzzle Brake (brand part no. 55DA5B2) is machined to the same exterior dimensions as a mil-spec A2 flash hider, threaded 1/2-28, and built to allow direct QD attachment of both CMMG DEFCAN-556 and DEFCAN-762 suppressors. It also doubles as a pin-and-weld muzzle device for shooters looking to bring a 14.5-inch barrel out to a legal 16.1-inch non-SBR configuration — the SVD brake comes set up and ready with everything needed to permanently attach it, aside from the welder and welding skills.

Frequently Asked Questions

Does this brake itself require NFA paperwork? No, it’s a standard muzzle device. Pinning and welding it to a 14.5-inch barrel to reach 16.1 inches is what keeps that build non-SBR — the brake itself is unregulated.

What suppressors does this mount? CMMG’s DEFCAN-556 and DEFCAN-762 suppressors, via direct QD attachment.
