I bought the newest and best version of the Kobra, I believe it was the EKP-8-01S or something like that..(cant remember exact name). Anyway, I did not use it on a real AK47, but on an Airsoft ak47. I was not very happy with the scope. Mounting it required drilling of holes for the EKP side mount plate into the reciever. Even though I measured carefully, these holes were slightly off I guess, and the scope would not adjust vertically enough to get the thing within a few feet of the target at 100 feet which was what I was trying to do. So I bought a new reciever, and tried the procedure over again. Once again, could not get it the firing point within adjustment. So I could never use the scope really. However, I will say this -- it looks cool, it has a nice mix up of reticles which are all very nice for close quarters. Oh the other thing I didn't like was that the locking lever wouold never go down all the way so I was always afraid it would get bumped open and then fall off.
