Pair of 1" stainless high rings from a No. 1. Very good condition, some wear on screws but they work perfectly. They are not marked but they do measure 9/16" from the top of the base to the bottom of the ring. These will fit any Ruger where the rings heights are the same, such as the No.1, Mini-14, or Blackhawk Hunter.
