The Karabiner Modell 1931 (officially abbreviated to Kar. 31/Mq. 31; commonly but incorrectly known in civilian circles as the K31) is a magazine-fed, straight-pull bolt-action rifle. It was the standard-issue rifle of the Swiss armed forces from 1933 until 1958 though examples remained in service into the 1970s. It has a 6-round removable magazine, and is chambered for the 7.5×55mm Swiss Gewehrpatrone 1911 or GP 11, a cartridge with ballistic qualities similar to the 7.62×51mm NATO/.308 Winchester cartridge. Each rifle included a 6-round detachable box magazine with matching stamped serial number. A stripper clip can be used to load the magazine from the top of the receiver.
