RE: How do these sights work?
i just bought the HHA lo-5500. the one pin, rheostat adj. for pin intensity. just shoot it in at whatever distances you want, and mark the label to coincide with your preferences. i will NEVER go back to a multi-pin sight again. your field of view, and ability to pin point your target area is so... much easier. i shoot ten times as accurate at 40-50 yards than i did before.
