G & H still has the double lever base for 100.00. It is flat and not drilled, if your gun is drilled the chances of the holes lining up on a used base is not good. I have a 22F BRNO that someone removed the side mount, after trying 2 or 3 used bases I am going the new base route. G & H web site for mounts is http://www.griffinhowe.com/mountsandpads.cfm
