Yankee Hill Machine YHM-5M2-QD QD Muzzle Brake | 1/2-28

The Yankee Hill Machine YHM-5M2-QD is a quick-detach (Q.D.) muzzle brake and suppressor mount engineered for use on AR-pattern hosts. It uses a five-port design and a Q.D. mounting surface to allow rapid attachment and removal of compatible Turbo/Turbo-K suppressors while providing additional recoil reduction compared with a simple flash hider. Constructed of steel with a black finish, it includes a shim kit for proper alignment and timing.

Typical applications include serving as the mounting interface for a Q.D. suppressor system and as a muzzle device for precision and high-volume range work where faster suppressor attachment and controlled recoil are priorities.
