The rings are NEW and never mounted, polished (bright) stainless steel, and for 30mm scope body. They can be used with a 1.0in scope body but require Delrin (spelling?) ring inserts available from Cabellas and other sources. (The inserts reduce the ring inside diameter from 30mm to approx25.4mm or 1.0in.) I have a NEW unused set of Delrin rings that I will include for $10.00 if you are interested.
