YHM Fat Cat 5.56 — SRX CAT Endcap

The YHM Fat Cat 5.56 with SRX CAT Endcap is Yankee Hill Machine’s large-bore 5.56 suppressor with their SRX (Suppressor Ready System) CAT (Closed-end Adjustable Technology) endcap configuration. The Fat Cat’s oversized bore reduces backpressure and first-round pop on 5.56 hosts. The SRX mounting system provides fast tool-free suppressor changes. The CAT endcap variant modifies the endcap configuration for specific performance characteristics.
