I am planning on putting a Simmons .22 mag scope on my 10/22 - plus a decent new base and rings (like Leupold 57315 Integral See-Thru Ringmount). In surfing the net it appears that these Leupold rings have several different types of base attachments. How do I what kind of base will match up with these rings? Would like to do a decent Weaver-style base. Can't find this info anywhere. Ideas???
