Kulsprutegevär m/21 (Kg m/21) were M1918 BARs initially built in the US to Swedish specifications; the main differences to the M1918 were the detachable pistol grip, spiked bipod and use of the 6.5x55mm round. First produced by Colt, and then under license by Carl Gustafs Stads Gevärsfaktori in Eskilstuna, Sweden. The Kulsprutegevär m/37 variant, introduced in 1937, added a quick-change barrel and was in use by the Swedish Armed Forces until the 1980s.
