Product Description The Yankee Hill sRx Quick-Detach (Q.D.) Short Flash Hider is a low-profile muzzle device designed to pair with the YHM sRx system for a sleek, repeatable suppressor mounting setup. Built from steel with a black phosphate finish, it uses a forward internal taper seal that locks the suppressor interface in place and helps prevent gas and debris from building up on the threads during use. The sRx system is designed to be "timeless," eliminating the need to shim or time the device, while adding minimal length and weight to your suppressor stack. This sRx flash hider is intended for barrels threaded 5/8"-24 and must be used with the YHM sRx Adapter (YHM-4400) for proper operation. The sRx interface is compatible with industry-standard HUB (1.375" x 24) suppressor mounting threads via the Q.D. adapter/mounting interface.
