Wow, that is a bit of a head-scratcher. My hunch is that someone (not Springfield) built a "carbine".

Your stock is a very nice later type of model 1896 carbine stock with two 'cartouche' stamps, which is a bit unusual, (and to me, seemingly unnecessary).

Your barrel is a carbine barrel. The front-sight blade may be correct, but, usually the small "C" is out of view on the 1896 carbine blade.

Your rear-sight is a model 1896 rifle-sight.

Your bolt is a model 1898 bolt.

Your 1894 dated receiver has been 'notched' for the bolt 'hold-open pin'. This alteration to early (Rifle) actions was done at Springfield Armory in the late 1890's and early 1900's.

IMHO - The mixture of rifle rear-sight, 1898 bolt, later 1896 carbine stock, and 1894 marked action - updated with 'notch', makes it very likely your Krag is a 'parts gun'. (I'd be happy to hear different).
