The Yankee Hill Machine Fat Cat is a compact suppressor designed for .223 Rem / 5.56 NATO use. It ships with an sRx quick-detach 1/2×28 adapter and a Mini sRx muzzle brake, and includes a Cat endcap. The unit is full-auto rated and finished in matte black for durable service use. Its larger diameter increases internal volume relative to many short cans, which helps manage sound characteristics for a compact package.
