Availability: In Stock
The Yankee Hill Machine Co sRx Q.D. Muzzle Brake is a short, quick-detach brake designed to work with the YHM sRx suppressor system. Built for shooters who want a low-profile, minimal-footprint setup without compromising on functionality, this 11/16"-24 tpi brake pairs with the sRx Adapter to deliver a suppressor mounting solution that's as refined as it is practical. The brake itself adds just 1.675 inches to your barrel (measured on barrels with 0.6" threads), keeping your overall length trim while maintaining the rugged performance Yankee Hill is known for.
The sRx system solves one of the perennial headaches of quick-detach suppressors: shimming and timing. The internal taper seal locks your suppressor firmly in place and creates a tight gas seal right at the threads—no accumulation of carbon, gasses, or debris. This design is purposefully simple; there are no moving parts to wear, fail, or fuss with. The brake is machined from 4140 steel and finished in black phosphate, giving it a clean, integrated look on the barrel and the durability to handle serious shooting.
If you're building a precision rifle, a hunting rig, or any platform where suppressor compatibility matters and you care about keeping the profile sleek, the sRx brake is purpose-built for that role. It's lighter than many comparable Q.D. systems and designed from the ground up to work seamlessly within the YHM sRx ecosystem. Note that the brake must be paired with the YHM sRx Adapter (YHM-4400) to function as intended.

| Length | 1.6875 inches |
| Diameter | 0.75 inches |
| Material | 4140 Steel |
| Finish | Black Phosphate |

Yes. The sRx Short Muzzle Brake must be paired with the YHM sRx Adapter (YHM-4400) to function. The adapter provides the mounting interface between the brake and your suppressor.
The sRx system uses an internal taper seal that locks your suppressor in place without requiring shims or timing adjustments. The seal also prevents gases and debris from building up on the threads, reducing maintenance headaches and keeping your suppressor threads clean.
The brake adds 1.675 inches to barrels with 0.6" threads. The brake itself is 1.6875 inches long, making it one of the shorter options available for suppressor mounting.
This model is 11/16"-24 tpi. Yankee Hill also makes the sRx brake in 5/8"-24 and 5/8"-32 versions, so verify your barrel's thread size before ordering.
