50mm Riflescopes will almost always use HIGH rings in a given style. In certain instances, such as with extremely heavy barrels or some makes of firearm, SUPER HIGH rings may be necessary.

42-45mm Riflescopes will almost always use MEDIUM rings in a given style. In certain instances, 45mm scopes may require HIGH rings.

40mm Riflescopes will almost always have enough clearance with LOW rings in a given style, though MEDIUM rings will give slightly more clearance, particularly when using a barrel with a thicker shank portion or a heavier contour.

28-36mm Riflescopes will almost always use LOW rings in a given style. Again, in certain instances of a heavy barrel or heavy shank portion of a custom barrel, MEDIUM rings may have to be used, but LOW rings will almost always suffice.

20mm Riflescopes will almost always be able to use LOW rings, but in some cases may also use SUPER LOW rings. In this instance, bolt handle clearance of theOCULAR bell will come into play more so than objective/barrel clearance and should be carefully considered.

VX-3L 50mm Riflescopes will almost always use LOW rings, but in some instances, where there is a very small barrel shank or relatively light barrel, they will be able to use SUPER LOW rings for the lowest practical mounting. Again, as in 20mm riflescopes, OCULAR bell versus bolt handle clearance will be more critical in many cases than objective bell/barrel clearance.

VX-3L 56mm Riflescopes will almost always use LOW rings, but in some instances, where there is a very pronounced barrel shank or relatively heavy barrel, they will use MEDIUM rings.

VX-3L Riflescopes can not be mounted in SUPER LOW rings with a one-piece base, as the power selector ring will impinge on the rear of the base.
