This rail will not work on ruger m77 rifles without two different size rings - Sun Optics Ruger To Weaver Adapter

When I ordered this I specifically asked if the mount required two different size rings like the Ruger Mounts. I was told NO. After waiting several months(the item was backordered) I find that if this adapter if used with two equally tall rings your scope will be pointing at the moon. It appears to be roughly .075 lower in the back than in the front. Someone somewhere really dropped the ball on engineering this gadget. Unless you can find Weaver rings that are comparable in height ratio as Ruger rings this is a waste of money!
