I have a S&B 3 x 12 x 50 on two custom mausers with the lowest scope bases I can find and the lowest scope rings made, Ken Farrell 30mm lows, and my scopes are almost a perfect fit. I do not think it is possible to get a 50mm objective scope lower than this setup. So one would think your mediums should work fine with zero issues. But as stated, you can't go by the low, medium, high designations as nothing is standardized. You'll have to do research to be sure.
