With the cut down barrel, stock and incorrect front sight, why not just leave it as a nice sporterized Krag? You can keep the rear peep sight as is.

You will not be able to return this Krag to its original military configuration. If you want an original military Krag, rifle or carbine, you will have to keep looking. There are many out there for sale.

But, people do like the sporterized Krags for shooting, if not collectible. Even Krags with pitted bores can be good shooters.
