The YHM Fat Cat® packs full-size 5.56 performance into a compact, reduced-blowback package. Built from 17-4 stainless steel with a Cobalt 6 blast baffle, it’s full-auto rated, just 4.5" OAL with the sRx® adapter, and its larger 1.94" diameter adds internal volume for a lower, more pleasant tone (~139 dB at the muzzle).
