Went together nicely. I torqued them to 15 inch pounds in a pattern so as to get the scope level. Scope mounted in about 5 minutes. I called Leupold for their ring height specifics. They're very good. I use Leupold for everything I can with a few exceptions that aren't worth mentioning.
Cons: don't not work
