The Combat Applications Technology CAT/RAT is a multi-unit modular silencer system intended to suppress 300 BLK personal defense weapons (PDWs). Its advanced hybrid technology, fully adaptable performance, and specialized design for the SIG SAUER MCX family of systems, makes it one of the most unique examples of high performance suppressed small arm system optimization evaluated by the PEW Science Laboratory, to date. The end user may choose to field the CAT RAT in covert operations, high volume fire training scenarios, or close quarter vehicle environments and not sacrifice weapon system reliability. The CAT RAT is capable of suppressing both subsonic and supersonic 300 BLK from the complete range of MCX and Rattler system barrel lengths, as well as from other 300 BLK systems.

In this review, the CAT RAT system performance metrics depend upon suppressing a subsonic intermediate rifle cartridge on a short barrel gas-operated rifle, which is an incredibly difficult task. How would the three CAT RAT configurations perform on your 6.75-in 300 BLK SIG SAUER MCX or Rattler AR-18 system?
