YHM Fat Cat 5.56mm QD Suppressor w/Mini sRx Muzzle Brake Cat End Cap 5.56mm Stainless Steel/Cobalt 6 Black 1/2×28

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 Cobalt 6blast baffle. The combination of these materials allows the suppressor to be full auto-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 our 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. Available in either standard or Cat’s Ass endcap.
The Fat Cat® includes the sRx® 1/2” x 28 QD Adapter Mini sRx® Muzzle Brake (1) YHM-2007 and (1) YHM-2146.

All YHM products are also backed by our Limited Lifetime Manufacturer’s Warranty.
