Anyone mount a scope on one? I've got two, one of which has been 'sporterized' (barell cut down a little). The base mounting holes on top of the rifle are very far forward...

I would just mount a scope on it the same as you would any other rifle. I would put the scope abovethe receiver and call it a day, unless that is prohibited by action movement, in which case I would use a long eye relief scope just ahead of the receiver.

I may be wrong on this, but it seems to me that the rear receiver ring on the Krag is split to allow the bolt to be removed. In that case, a long eye relief scope might be your only option.

Most scoped Krags I've seen use an offset scope mount.

I mounted a scope on a Norwegian Krag once using a Williams side mount with HCO rings. By filing a bevel on the ejector bar, I got it to kick empties out to the right side (as seen from the ear), instead of straight up, as they do if unaltered. This allowed me to mount the scope over the center of the bore instead of offset. Worked great, and I see no reason why one could not do the same with a U.S. Krag.......

The Williams is one strong mount!!
