Re: Please help first setup
What part is moving, the bases or the rings? Your base might not be screwed in tight as well. I would take the scope and rings off, tighten the bases, then remount the rings and scope. If you are not familiar with how to mount a scope, either do some searching on here or take it to a gun shop and pay them $15 to do it (or take it back to the store you bought it from and make them do it for free).
