I have a sporterized 1898 Krag.  The barrel is now 24" long and the front sight is dovetailed in.  The front sight appears to be the regular military base and blade.  The front sight is directly at the 12 o'clock position (within a few thousandths) as measured using a square and calipers and using the underside of the magazine as a reference.

However, the rear sight (model 1901) is mounted almost .020" to the left of center.  It's really noticeable when the ladder is raised and it leans off to the left.

Is this normal?  I'd expect the rear sight base to be mounted right at the 12 o'clock position like the front sight.  Can someone with a full military condition rifle raise their sight leaf and see if it leans to the left relative to the front sight?
