The Karabiner Modell 31, better known as the K31, is a Swiss bolt-action rifle chambered in 7.5x55mm Swiss and feeding from a 6-round detachable magazine. It is a straight-pull rifle made to extremely tight tolerances, for which it has earned a name amongst marksmen worldwide as one of the very few mass-produced rifles achieving sub-MOA accuracy out of the factory. The K31 served as Switzerland's standard service rifle during World War II (though it wasn't used in combat). As it is currently being replaced with a modern battle rifle, K31s are being sold across the world, fetching enormous prices from snipers (particularly in Oceanyka).
