It "almost" all comes down to the size of the objective, but it's not the only thing which can foul. I had a 52mm Redfield, went to put it in a medium one piece mount but the part around the turrets (is it called the saddle?) would have been crushed by the mount if I'd tightened it, machined 1mm off the top of the mount to make it fit.
