Trijicon's IR Hunter MKII 1.5x thermal weapon sight features a 1.5-12x magnification, 640x480 MicroIR thermal core, 12 micron technology, Emagin OLED display, 60hz fast frame rate, and clip-on feature. Includes sight, LaRue tactical weapon mount, eyeguard, tactical soft case, operator's manual, QRG guide, and batteries. The IR Hunter's turret system is built to intuitively access the optic's user interface - sounds complicated, but this system is built to be user-friendly, and only a couple of minutes on the Hunter will give a user enough know-how to quickly access different reticles, digital zoom functionality, switch polarity from black hot to white hot, and zero the optic. There isn't a better way to perform all these functions easily - especially with gloves on or in the dark. The IR Hunter combines the performance of military-grade thermal optics with the ease of use and precision of high-end rifle scopes. The IR Hunter can also be used and zeroed as a clip-on device, though the max magnification of the day sight used in this fashion is 3x. Trijicon's electo-optic products are 100% American-built and are taken to the next level of care and top-of-the-line components. These are truly affordable thermal optics that blow away their competition. Trijicon IR HUNTER MK2 20MM UPGRD TO MK3 35MM
