Micro Green Dot & AK style rifle...
Will the Micro Green Dot reflex sight work with an Ultimak mount on my AK?
Or does it sit too low?
It will work. It sits a little too high for co-witness though. I haven't tested the the reflex sights resistance to heat on the Ultimak, but it worked for a day of plinking when my Micro battery was dead.
Go with the micro fixed base for any AK. Not sure about co-witness.
