I have for sale a set of ADM guide/finder scope rings with Vixen-style saddles, to suit 50-60mm scopes. The rings have Delrin-tipped screws and hold tubes of about 45mm to about 70mm diameter.
Included are two rings, two saddles, two spacer blocks and socket-head bolts, as pictured.
The set is in excellent condition (practically unused). I'm asking $110 shipped to anywhere in Australia.
