Hank,not an expert on rings and bases so here goes. If you have the conventional target type bases already installed you can use rimfire rings
as rings for the redfield 3200 scope. I believe that this was suggested in more than one answer to a post similar to yours. Hopefully someone with more info will come along and provide better info. You could try gary fellers (google him) as he has a website listing what he has for sale.
