'kbthekid44' - Welcome to the KCA Forum.

Your Krag was marked "model 1898".

A Krag in the 470XXX serial number range was likely built, as a rifle, in the period of July to October of 1903.

FWIW - Many of the 1903 period Krags, (I have seen and recall), seem to have the model 1901 rear sight.

(There is a "belief" that Krag rifles in use by the U.S. Army, after 1905, tended to have the 1901 sight, because it was similar to the sight eventually used on the 1903 Springfield. The model 1902 sight may have been more common on National Guard arms). - It is possible this is all myth.

Fact - U.S. Krag rear-sights were 'a continuing saga' and were sometimes changed.

A Krag built in 1903 may have started out with the model 1902 sight and had it changed, at a later date, to a model 1901 sight.

Either the model 1901 or 1902 sight is probably credible on your Krag. These two sights use different and model specific wooden hand-guards and mounting-screws.

"Ya pays yur money and ya votes yur choice"!

OBTW - The front sight is the same for both of these sight models.
