Hello
According to the 1976 Williams catalog
" All Williams QC Mounts now have an eccentric bushing with a collar that can be turned with a screw driver of similar object, to obtain preliminary adjustment and insure a good mounting job. It is not necessary to remove bushing to turn it, and it is not necessary to remove mount to obtain windage adjustment."

So, if you have a Williams QC Side Mount SM-MS-52/56 with the Offset A rings, perhaps, possibly, maybe.

BUT I would suggest these are only rough windage movements and not fine sighting in movements. You may have to shim the mount to get exactly what you want.

Mike
