I measured the following off of my VEPR:
Height over the receiver is 14.79mm from the top of the dust cover to the outside angled edge of the picatinny rail (not the very top)
Thickness of the side mount plate, not including the dovetail, 4.04mm
Total width of the receiver, 34.21mm
For me, only the UTGs lined up over center. Return to zero has been good, but I've only tested it a few times at the range, and only out to 200 yards.
