Would somebody be able to tell me how these fit to a sako. Do they slide into the dovetails, or does the reciever have to be drilled an tapped???

don`t know about S&K,but they probably slide on and hammer tight(my leuopolds did)and they don`t give any at all,yet. 20+ yrs
doesn`t take much of a blow to get them tight.remember, it will take at least as much to get them back off plus some!

well,maybe it was redfields because they aren`t quick releases
they all work the same

No, the S&K's are completely different than anything else with the possible exception of Conetrols. (don't let Conetrol here that!!)
They are a projectionless ring, base system that uses a 1 piece ring that gets stretched around the scope and then attached to the bases by opposing coned setscrews.

I looked for how the SAKO bases worked on the S&K site but couldn't find anything to help.
