These are Copper M22's, they do have a heavy straight contour barrel.on them. My other M22's have 30mm tubes so are no help.
This is the best that I can do with something simular.
Both the Leupold and Talley rings are in medium height and the scopes are the Nikon 5x20x44. You can see the clearance between the objective bell and barrel.
I did not measure the heights of the rings nor the clearance but hope this helps.
