I have a SWFA SS scope and TPS rings. When i place the bottom half of the ring between the eye piece and turret they fit perfectly but when i place it between the turret and objective theres a gap about the thickness of a credit card. Its not the rings themselves because both rings give the same results. However when i played with the top half of the rings one of them is able to fit perfectly on both sections. When i compare this top half to the rest of the rings parts that don't mate i could't see any difference. Any suggestions on what i should do? I was thinking about lapping it. Here are some pictures
