Historical profile
Developed under wartime pressure to give Swedish infantry a rapid-fire weapon without relying on foreign supply; production began in 1942 at Eskilstuna.
It was the first service rifle to adopt the direct-impingement gas system, with gas acting straight on the bolt without a piston — a solution later revisited by Eugene Stoner on the AR-15/M16.
Modernised as the Ag m/42B in 1953 with receiver and sight improvements, it remained in second-line service until the 1960s, replaced by the 7.62 NATO Ak 4 (HK G3).
