The FAMAE Firearms Family is a product of the Chilean state-owned manufacturing company Fábricas y Maestranzas del Ejército and the Swiss Arms company, formerly Sig Sauer. The Chileans have licensed the original Sig540 design to outfit their armed forces.
This platform from the 1970s has been adapted into many variants with specific weapons for military and police use. They cover every base: large 7.62×51 designated marksman rifles, solid 5.56 assault rifles, short barrelled paratrooper carbines, 9mm sub-machine guns, snub-nosed personal defense weapons, and even police-specific options chambered for the World War II .30 carbine round.
Some of the semi-auto variants are exported to Canada, where they find a welcome home in the gun-starved north.
