The YHM SRX Short QD Muzzle Brake in .578-28 thread is a quick-detach muzzle device built for shooters who want a low-profile suppressor setup without compromise. Part of Yankee Hill Machine's sRx (Suppressor Rx) system, this brake pairs with the YHM sRx Adapter (sold separately) to deliver a sleek, functional mounting solution that keeps your barrel clean and your rig looking sharp. It's designed for those who care equally about aesthetics, reliability, and ease of use.
The standout feature is the internal taper seal positioned ahead of the threads. This design locks your suppressor firmly in place and forms a tight seal around gases during operation—meaning no carbon buildup on the threads, no shimming, and no timing headaches. The taper remains consistent every time you mount or dismount, so you get repeatable performance without the fuss. The brake itself adds minimal length and weight to your suppressor stack, keeping your overall setup compact and maneuverable.
Built from 4140 steel with a durable black phosphate finish, the sRx Short brake is engineered to handle serious use. It can remain permanently attached to your barrel if you choose, or swap suppressors as needed via the quick-detach system. Whether you're running a precision rifle, a short-barrel defensive setup, or anything in between, the straightforward design and proven YHM quality make this a no-fuss choice for suppressors-ready barrels.
