The Yankee Hill Machine sRx QD Flash Hider, Short (brand part no. YHM-4445-24) is the muzzle device half of YHM’s sRx suppressor mounting system, cut to a 5/8-24 tpi thread for .308/7.62 NATO hosts. Finished in black phosphate steel, it must be paired with the YHM sRx Adapter (YHM-4400) to complete the mounting interface, which uses an internal taper seal in front of the threads to lock a suppressor on and form a tight seal against gas and debris buildup. Like the rest of the sRx line, it adds minimal length and weight to the setup and needs no shimming or timing to the barrel.
