The Swiss SIG SG510 was produced between 1957 and 1983. It is also known as the Fass 57 (French/Italian, for Fusil d'Assault 57/Fucile d' Assalto 57) or Stgw 57 (German for Sturm Gewehr 57). The SG510-4 model, which is shorter and lighter than the original SG540, uses 7.62×51mm NATO munition and is in service by the Chilean and Bolivian armed forces.
