The Swiss Mannlicher Model 1893 carbine was a straight-pull carbine designed by Ferdinand Mannlicher for use by the Swiss cavalry troops.
The Swiss military was in need of a cavalry carbine for their mounted units, so they tried shortening the existing Schmidt–Rubin 1889, but its action proved to be too long to be effective to maneuver with while mounted, so the Swiss government began trials for a new carbine.
The Mannlicher straight-pull design was chosen for its compactness.
[1] It was carried by side sling swivels and didn't feature a bayonet mount.
Many were intentionally smashed during drills, so today combined with their small manufacture number they are quite rare.
