Yankee Hill SRx QD Mini Muzzle Brake 1/2x28 9mm Black Phosphate

Yankee Hill SRx QD Mini Muzzle Brake is a compact, low-profile muzzle device designed to integrate with the YHM SRx mounting ecosystem. It features an internal taper seal in front of the threads to lock the suppressor mount in place and form a tight seal that helps keep gas and debris off the threads during use. Designed for 1/2x28 threaded barrels and intended for 9mm or smaller calibers. For use with the SRx system, it must be paired with the YHM SRx Adapter (YHM-4400) and is compatible with HUB 1-3/8x24 interface.
