Yankee Hill Machine sRx Short QD Muzzle Brake .578x28 Black Phosphate

The Yankee Hill Machine sRx Short QD Muzzle Brake is a low-profile, quick-detach muzzle device built around YHM's sRx (Suppressor Rx) suppressor-ready platform. Designed for shooters who want a clean host rifle that swaps directly to a compatible YHM sRx suppressor, this Short variant uses YHM's no-timing-required brake geometry and internal gas seal design for a sleek, suppressor-ready setup without the clocking hassle of a traditional muzzle brake.

Precision machined from 4140 steel and finished in black phosphate, the Short measures just 1.6875" long with a .75" diameter at a weight of 1.472 oz, keeping the host rifle front-end light and unobtrusive. The .578x28 thread pitch fits any barrel cut to that spec.

The quick-detach mount allows the shooter to attach and remove a compatible sRx suppressor by hand with no tools, and a shim kit is included for proper installation. Built around YHM's sRx ecosystem, this Short brake pairs with a YHM sRx Adapter for a sleek, low-profile, suppressor-ready setup.
