The Ruger Stainless 30mm Medium Scope Ring is a single medium-height ring from Ruger for scopes with a 30mm main tube, sized by Ruger for a 42 mm objective (Ruger part no. 90315). It is finished in Stainless, the maker’s own finish name for this ring. Ruger sells it individually as a genuine factory accessory, so you choose the ring for each position on the rifle yourself. Matching the medium height to the 42 mm objective bell on your scope is the main decision with a ring like this. It suits a hunting or range rifle that needs a plain, dependable factory scope ring.
