Scope Highth
How high your scope will be is determined by the choice of rings and the size of the eye piece on the scope. The important thing is the eye piece needs to clear the rear sight aperture. Most scopes can be mounted using low rings like the TPS Tactical model. Keep in mind that some brand of low rings may be lower than others and cause problems.
I'm mounting Leupold MK4 scopes to Sadlak mounts with TPS 30mm low rings. They allow about 1/10" of clearance between the scope and rear aperture. There is plenty of clearance in the front for up to 50mm objective lenses and probably 56mm lenses.
Worst case senario is you might need medium rings, but this will probably only be true when using very large scopes.
