This probably falls outside of "midrange" but I shoot matches with a guy who runs an AK with a Zenitco B-33, on top of which he has an Eotech and a Vortex 3x magnifier, he seems pretty fond of that set up.
I asked for his opinion about LPVO's on AKs and he said RS Regulate might be the better option as it'll bring the weight down some. I was actually just thinking about this topic the other day, but my Tantal's lack of side rail came up as an issue.
