Clip-on mounting and sensor specs

The Cronus ATS Pro attaches forward of your existing riflescope, preserving your day-optic zero while adding thermal detection. This configuration works with most standard scope rings and Picatinny rails. The 35mm thermal core captures heat signatures in complete darkness and poor visibility conditions.
