[QUOTE="Senderofan, post: 1081825, member: 13831"] No...Not necessarily. It depends on other variables like barrel contour, height of scope base(s) and perhaps even the true outside diameter of the front objective ( some have very thick material around the front objective lens) as well. All of my 56mm front objective scopes have 1" rings. I did have to use 1.25" rings for a scope with a 60mm front objective.
