Listed here is a classic Swiss K31 straight-pull rifle, chambered in 7.5x55 Swiss. Produced in 1943, this rifle features the legendary Swiss craftsmanship and renowned accuracy that have made the K31 a favorite among surplus collectors and shooters alike. The bluing is excellent, and the hardwood stock shows only minor handling marks, especially for a rifle of this age.
The K31 (Karabiner Modell 1931) is a Swiss straight-pull bolt-action rifle chambered in 7.5x55mm Swiss (GP11). It served as the standard-issue rifle for the Swiss Armed Forces from 1933 to 1958. This model is a 1957 and the pics above is the model in stock with Bayonet!
