I'm trying to decide on a few different scope/gun options and combinations. I have a ruger 10/22 with a base mounted on it, I'm wondering how I can tell if this is a standard type base and whether I can switch a scope from a centrefire rifle to this one without changing the rings. At this time I have nothing to compare it to. If someone knew the dimensions of a standard centrefire dovetail type base that would be really appreciated.
I hope this makes sense
