The Apparition Instruments AI 3CM is a modular silencer system intended to suppress 300 BLK personal defense weapons (PDWs). Its advanced hybrid technology, borrowed from the CAT RAT system, provides relatively balanced suppression performance and flow rate in its long configuration and somewhat competitive operator protection in the short configuration. The AI 3CM is capable of suppressing both subsonic and supersonic 300 BLK from short barrel personal defense weapons and other 300 BLK systems.

In this review, the AI 3CM 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 two AI 3CM configurations perform on your 6.75-in 300 BLK SIG SAUER MCX or Rattler AR-18 system?
