The FM1957 is a Swedish prototype battle rifle based on the Ljungman Ag m/42 semi-automatic rifle. Along with the FN FAL M14 Rk 60 and GRAM 63 it was in competition to replace the bolt action Mausers and the Ag m/42 rifles in Swedish service during the early 1960s but lost over the Heckler & Koch G3 (license built as the Ak 4 in Sweden). The FM57 therefore never entered serial production.
