What do the rifle scope measurements mean?

Answer 1

Two numbers, such as 4x32, indicate the magnification (4 times) and the size of the front (objective) lens- 32 mm. A bigger lens is usually brighter. Three numbers, such as 6-24x42 or 6x24x42 will indicate a variable power scope- from 6 to 24 power, with a 42mm front lens.
