Great info there. I don't want a scope that loosens up, especially at night, and never was wild about the joystick arrangement. We don't have hogs here, so no fast shooting or muzzle rise to worry about. Although I like the small form factor of the REAP-IR, a little more weight is not too big a deal because nighttime coyote hunting (my reason for buying) is pretty much a stationary situation, except for a couple of relocations. I will re-visit the MKIII based on what you say. I did not want to go MKII, because it seemed like IRD threw MKII users under the bus regarding software updates, once the MKIII came out.
