FM57 rifle
The FM1957 is a Swedish prototype battle rifle based on the Ag m/42 semi-automatic rifle. Along with the FN FAL, M14 rifle, Rk 60 and GRAM 63 battle rifle, it was in competition to replace the bolt action Mausers and the Ag m/42B rifles in Swedish service during the early 1960s but lost over the Heckler & Koch G3 (license built as the Ak 4 in Sweden).
