Yankee Hill 4445MB24 sRx Short Q.D. Muzzle Brake 5/8x24

The Yankee Hill 4445MB24 sRx Short Q.D. Muzzle Brake is a low-profile, quick-detach muzzle device purpose-built for the YHM sRx suppressor mounting system. Machined from 4140 steel and finished in a corrosion-resistant black phosphate coating, this short brake adds minimal length and weight to a suppressed host rifle or pistol while delivering the refined, repeatable lock-up that the sRx system is known for.

This .45 caliber variant is cut with 5/8"-24 threads to match standard .45-cal barrels. It threads onto the host barrel and mates with a YHM sRx Adapter (sold separately), which clamps to the brake and provides the industry-standard HUB 1-3/8"x24 interface for the matching sRx suppressor. An internal taper just in front of the threads seats against the adapter to lock the system together and form a gas-tight seal that contains blowback while the suppressor is in use.

At just 1.6875" long and 0.75" in diameter, the 4445MB24 keeps the overall build as short and light as possible without sacrificing the accuracy and recoil-mitigating performance expected of a Yankee Hill muzzle device. Proudly made in the USA.
