This 5.56 NATO suppressor sports new baffle geometry resulting in reduced blowback. Built with the same care, quality, and attention to detail that has defined the YHM brand for generations, the Fat Cat was created to provide a compact suppressor with great sound. The Fat Cat is made from 17-4 stainless steel along with a heat-treated blast baffle. The combination of these materials allows the suppressor to be -rated and designed for rigorous use. The overall length measures just 4.5″ with the sRx adapter installed. That’s a full inch shorter than their Turbo K model with its included adapter. The Fat Cat’s larger 1.94″ diameter creates more internal volume resulting in a lower, more pleasant tone. With an average sound pressure level of 139dB at the muzzle, the Fat Cat is quite the performer for its size. The Fat Cat includes the sRx 1/2″ x 28 QD Adapter, Mini sRx Muzzle Brake, (1) YHM-2007 and (1) YHM-2146.
