An original Krag front-sight pin has a slight taper and should be driven out 'left to right'.

Per Brophy, model 1898 Krag rifle blades measured an average of .413" (for ten samples measured).

(PM me, if you are unable to locate an original blade and pin. I probably have a spare I can sell).

Some photos of model 1898 rifle sight-blades. Second photo displays need to remove blade in order to remove front barrel-band. Last photo contrasts rifle and carbine blade.
