I purchase them cheap at gun shows and use them as needed around here.
I have found a way to spread the legs a wee bit so the slide over the scope tubes without marking/scratching them.
Dead blow hammer, piece oh plywood and lay the top rings belly down.
Rap them with the soft faced mallet slightly and see if they will slide over my 1" stainless rod.
Rap as necessary and then voila.........ready to use summore.
Just don't over tighten them is awl.
Or just wrap a piece of pop can around the scope tube, force the ring over the pop can aluminum (.004" thick) and pull the sheet fo aluminum out.
