Talley model number 730736, black matte 1 piece lightweight rings/bases for Cooper model 16, 22, 52 and possibly others (check Talley website). These are 30mm low rings. I mounted a 30mm Swarovski Z6 with 50mm objective on my Cooper 52 with these, and then changed the scope out for another within a few weeks. These are in new condition, no scratches, etc and come in the factory box.
$30 shipped.
