The YHM sRx Short Muzzle Brake in 5/8×24 is a compact quick-detach brake from Yankee Hill Machine (brand part no. YHM-4445-MB-24). It belongs to the sRx suppressor mounting system, whose internal taper seal locks the suppressor on and keeps carbon off the threads. The short body adds minimal length and weight to a suppressed rifle. This is the version for barrels threaded 5/8×24.
