1899 krag

[butlersrangers]

My opinion is that Krag carbines often have Rifle Rear-Sights because a previous civilian owner switched the more valuable carbine sight with a cheaper (and similar) rifle sight in order to make more money.

Only around 1,000 Krag model 1902 carbine sights were made.

The 1902 carbine and rifle sights have identical 'tops'.
The carbine base has a shorter 'ramp' than the rifle version and is marked with a "C", normally on the right-side, but a few real ones have the "C" on the left-side of the base.
1902 sights are found both with the 'swing-up-peep' and without it, (on the rear of the eyepiece).

The elevation 'locking-knobs' will often have been repaired with the later oddly slotted 1903 knob.

(Note - The 1898 rifle and carbine sight-bases are similar to the 1902 bases and have a low ramp profile. These bases have an entirely different style of leaf spring.
The 1898 sight bases were scrapped but got reused by surplus dealers in 'parts guns'. The 1898 bases are only correct with an 1898 'top' and its three-notch eyepiece).
