The Ksp 58 (Swedish: Kulspruta 58, English: Machine Gun 58) is a Swedish variant of the Belgian FN MAG general-purpose machine gun, adopted by the Swedish Armed Forces in 1958.

History

After 1945, many countries were trying to produce their own machine guns based on the MG 42 design. In the early 1950s, Belgian arms manufacturer FN Herstal succeeded in developing a general-purpose machine gun called the MAG. The initial Ksp 58A version used by Sweden was chambered for 6.5×55mm, while the B and later models were chambered for 7.62×51mm NATO.
