Sounds like you have a Savage 23C. Really neat little rifles! Probably the easiest way to scope those is a two piece Weaver rail. I'd recommend taking it to a good gunsmith to have it drilled and tapped and scope bases fitted. Be aware though that the value of those rifles is increasing quickly. If it's a nice original example then putting a scope on it is going to kill its value. You have to make your own decision on that one.
