1. Set of used one time Leupold 30 mm rings. Front turn in, rear windage adjustable. They measure about 5/16" in from the bottom of the scope to the bottom of the ring. These are just like new. Take $30.00 including parcel post. 2.Have another set of like new 30 MM Leupold rings that are still on the bases. Everything is in great shape. However I lost one scope screw and one of the base screws. Not sure of the height but there is about 3/8" of metal beneath the scope bottom and the top of the mounting surface of the rear ring. I recall these coming off a Mark V Wby but I believe they'll also fit the Rem 700, Vanguard and S&W 1500 rifles. Take $35 including shipping for rings and bases. These are both Matt black.
