well, I think I was just having a bad day. while cleaning, I took my scope off, to pull the nipple. I lost one of the screws. looked for about an hour or two. could not find it. hit wally world (side note:they are setting up for hunting season going to stock up on win #11). picked up a set of rings. I don't like the weavers they carry. so I went to a local hardware store and matched the screw up.
