Yankee Hill Machine
The Yankee Hill Machine SRX Short QD muzzle brake is a left-hand threaded muzzle device engineered for shooters who need quick-detach capability combined with recoil management. Designed with an M14x1LH thread pattern, this compact brake integrates seamlessly into modern rifle setups where fast suppressor swaps or brake changes are essential—whether you're running between range sessions, hunting different terrain, or testing suppressor compatibility without permanent installation.
Yankee Hill Machine is known for precision manufacturing and innovative QD platforms. The SRX line represents that commitment to modularity and reliability. The short profile keeps your overall rifle length manageable while the quick-detach system means you can transition from suppressed to unsuppressed shooting (or vice versa) in seconds, without tools or guesswork.
If you're building a left-hand threaded rifle or adding a QD muzzle device to an existing left-hand barrel, the SRX Short gives you access to YHM's suppressor ecosystem and a proven quick-detach interface. Pair it with compatible YHM cans for a modular, field-proven platform.
| Brand | Yankee Hill Machine |
| Product | SRX Short QD Muzzle Brake |
| Thread Pattern | M14x1LH (left-hand) |
| Type | Quick-Detach Muzzle Brake |
M14x1LH indicates a 14mm diameter metric thread with 1mm pitch and left-hand rotation—meaning the brake unscrews counterclockwise. This pattern fits left-hand threaded barrels; it will not fit standard right-hand threaded barrels.
The SRX Short QD muzzle brake uses Yankee Hill Machine's quick-detach interface, which is compatible with YHM suppressors featuring the same QD mount. Verify your suppressor has the matching YHM QD system before purchase.
We only have information on the muzzle brake itself; for details on included shims, crush washers, or additional components, contact us directly or consult the YHM product documentation.
This is a muzzle brake, designed to reduce felt recoil through directional gas ports. It is not a flash suppressor.
