Yankee Hill Machine sRx Long Q.D. Flash Hider, 1/2-28 tpi, Black Phosphate finish, 2.30″ overall length; designed to mate with the YHM sRx adapter (YHM-4400) for a low-profile suppressor interface.
The Yankee Hill Machine (YHM) sRx Long Flash Hider is a low-profile Q.D. muzzle device engineered for the sRx interface. It provides a tapered sealing surface ahead of the threads so a compatible sRx adapter and suppressor can lock on cleanly while minimizing added length and weight. The device must be used with the YHM sRx adapter (YHM-4400) and is intended for use in suppressor-ready carbine and precision/competition builds where a streamlined mount is desired.
