'timmholt' - Since your Krag is extensively altered for 'Hunting' purposes, (with cut-down barrel, re-shaped stock & added pistol grip, and dovetailed barrel-mount rear sight), an armory type front-sight will do little to make this Krag look more original. - IMHO

You might be better off just putting a nicer appearing 'Sporting Style' front ramp sight on your Krag. These are currently made in the 'solder-on' configuration and older style 'banded-ramps' show up on ebay and at gun shows.

You now have a solid model 1899 carbine barrel band on your Krag. I can't tell what is keeping it in place, except friction.

FWIW - A regular Krag rifle barrel-band, with clamping screw and sling-swivel, might be a better arrangement for shooting and carry.  The rifle band would not require any alteration and would just replace the carbine band, which is designed to be held in place with a flat-spring on the right-side of the stock tip.

Since this is an old family hunting rifle, you just might want to leave things as they are and enjoy it as a 'shooting heirloom'.
