FYI:

Lt. Col. William S. Brophy measured a sampling of Krag front-sight blades and illustrated the results in his book, "The Krag Rifle", page114.

1892 Rifle (rear sight) - front sight blade = .275" high

1896 Rifle (rear sight) - front sight blade = .286" high

1898, 1901, 1902 Rifle (rear sights) - front sight blade = .413" high

1896 Carbine (rear sight) - front sight blade = .266" high

1898, 1901, 1902 Carbine (rear sights) - front sight blade = .355"

(Note: These measurements are just the blade height and do not include the height of the Krag base, that was dovetailed and brazed to the barrel. The base was identical on all issued U. S. Krag models).

IMHO - It is very likely there are some 'issued' Krag front-sight blades that were probably filed and altered by Armorers and Match Shooters, to adjust the elevation of the point of impact.
