I believe they are talley quick release rings with bases. The bases look like they are in the correct places. This is a pre 64 winchester model 70 action they are on. I bought the gun last week with the scope, rings and bases on it. Shot it yesterday and had this problem so I put a known good trijicon scope on it and this morning had the same issue.
Sounds like they got the wrong bases on it. They probably put bases for a modern post 64 action on a pre 64. The rear bridge height on pre 64's is different than modern model 70's. Ran into this when putting modern bases on a pre-64. Some scopes may have enough vertical adjustment to compensate but the misalignment of the rings caused by the unequal base height stresses the scope tube and can bend it or leave nasty ring marks in your tube.
