I have 2 Leupold quick release bases with rings. For encore 1” rings. To me one of the black rings doesn’t tighten up like the others. I’ll include the black set but figure the black set of rings may not be usable. Includes all three mounting screws which I just happened to find in the package this morning by accident. $80 shipped for 2 bases and a set of silver rings and a set of questionable black rings.
