One of the major "problems" I noticed with my new Mosin is the sight is off. It looks like it is still in the same spot when it was staked in '39-'45, but as you can see from the picture, it is clearly way off center. It almost looks like the bead was bent to compensate for this? I'm at a loss of what to do. Center it? Buy a new one? Shoot it to see if its really off?
