It would break the bank but I would go with an ultimak rail ($100) and then mount an aimpoint R1 ($350) which is basically the same as the T1 without the nightvision settings.
I haven't used this set up in a while but if my memory serves me well if the R1 goes down you should be able to use your iron sights without removing the R1. My buddy has this exact set up, I helped him zero it and put a few rounds through it. It maintained zero and if I was still in the AK game I would get this set up.
ETA: There is also a much more inexpensive version of the red dot that is getting good reviews. I think primary arms makes it.
