If I were buying today, I’d probably buy a MK III in 35 mm. Although I really like the size/weight of the REAP-IR, I can’t warm up to the joystick. I’d want the 35mm for the wider FOV as I want to call them in within 150 yds, not try to snipe them way out there, and for detection, I use a scanner anyway. IRD/Trijicon seem to have an excellent customer service /quality record, other than IRD abandoning the MK II buyers when they introduced the MK III.
