Cervus, we tried pulling the bolt back very sharply also. Second rifle beretta sent me did the same thing. Thought about twisting the scope as Big RedHead noted, but just could'nt live with it. The marks on scope where on the squareish part, not just the cap of the scope. Some marks were almost dead center of the scope. I'm just glad they gave me my full refund. This was about a two month ordeal. Shot the first rifle one time, when I found out it's ejection problem. Thats enough to make a person sick.
