ATN's TICO series of thermal clip-ons mounts in front of a day-time scope and enables thermal vision in day or nighttime operations. There is no shift of impact, no need to re-zero or change of eye relief. The rugged ATN-TICO Series are lightweight and will not affect the balance of the firearm. A quick-release MIL-STD 1913 Picatinny mount allows for immediate attachment and detachment. The display is a color OLED matrix and has video output capabilities. The 50mm objective lens features a DLC coating to prevent scratches and dust. The ATN TICO-Series is available in two models; the TICO-336 and the TICO-640.
