Trijicon EO Mark II 20mm Thermal Riflescope 60Hz


The IR Hunter MK II is the perfect thermal weapon sight and with good reason. It is a combination of over 20 years of night vision system design and feedback from the original IR Hunter. This led us to our new improved MK II version that is only available in 640×480 because we only want to deliver the best. We chose to upgrade the sensor to the new MicroIR 12um Micro Technology that is extremely impressive and also uses less batteries. We also decided to combine the new sensor with a MIL.SPEC Emagin OLED micro display that delivers a super crisp, sharp image per your request. One of the key decisions when buying a thermal weapon sight is whether to get a dedicated or Clip-On system. The IR Hunter MK II allows you to have the best of both worlds. The system works as a Clip-On out of the box with no accessory required on a selection of 1x, 1-4x and 1-6x day optics.

Trijicon EO Mark II 20mm Thermal Riflescope 60Hz

We also added 60Hz fast frame rate to every MK II system at no addition cost to you. The fast frame rate will be useful for leading a shot of a fast moving target. Another nice feature of the new MK II is that the 12um Micron delivers 35% more magnification than a 17um Micron which means our 35mm lens is equal to a 50mm lens on a 17um system. This gives you more magnification for less money out of your pocket which might help explain why the IR Hunter MK II is the lowest cost 640×480 system on the market.
