Apparition Instruments

Apparition Instruments or AI, historically focused solely on defense development, has now expanded its expertise to support the little team at C.A.T. Together, we’re creating purpose-built accessories designed specifically to enhance the performance, usability, and integration of suppressor products. These are not generic add-ons — they are precision-engineered accessories developed to ensure seamless pressure compatibility with all C.A.T models. This collaboration brings the same level of innovation and technical research excellence found in defense applications to our users.
