Schmidt-Rubin K11 Short B/A Rifle- 7.5X55 (Swiss)
The Schmidt–Rubin rifles were a series of Swiss Army service rifles in use between 1889 and 1958. They are distinguished by the straight-pull bolt action invented by Rudolf Schmidt and use Eduard Rubin‘s 7.5×55mm Schmidt–Rubin rifle cartridge.
The Swiss at some point realized that its support troops, cavalry, and certain other units required a shorter rifle than what was currently available and so designed the Model 1911 carbine. The Swiss 1911 carbine being smaller, lighter and still lethally accurate, it became a favorite of the Swiss Army and its popularity contributed to the design of its successor the K31. Production of the K11 included conversion of the model 1900 and 1905 short rifles to the newer specifications of the carbine. For this reason the earlier short rifles are rarely found in their original state. The K11 was the last of the Vogelsgang/Rebholz rifles to be produced.
