Meprolight has a model and concept like that but the optic looks stupidly high. If they don't have a patent on a QD mount on tbe rear iron sight, maybe someone else will put something smaller and thinner on it, Holosun SCS perhaps.Closed emitters make sense, but I can't help shake the feeling they are also a great way to make people opt for higher price points. What would be great is if someone were to figure out a QD mount that adds no baseplate height to a pistol red dot. Then open and closed wouldn't matter as much because you'd just rip it off in a pinch and fall back on irons.
