The SG 540 is a 5.56mm assault rifle developed in the early 1970s by Schweizerische Industrie Gesellschaft (SIG, currently SAN Swiss Arms AG) based out of Neuhausen, Switzerland as a private venture primarily destined for export markets and as a potential replacement for the 7.5mm SG 510 automatic rifle known as the Stgw 57 in Swiss service.

Work on a new generation of lightweight rifle using the intermediate 5.56mm round began at SIG in the 1960s and resulted in the somewhat unsuccessful SG 530-1 design that employed a gas-assisted roller-delayed blowback operating mechanism which proved too complicated and expensive to manufacture. As a result, in 1969 SIG chose to dispense with the complex roller-delayed action opting instead for a design using the more robust and simple piston-operated rotating bolt locking mechanism (derived from the Soviet 7.62mm AK assault rifle). This combination was to be successful and the rifle entered production as a family of weapons consisting of the base 5.56mm SG 540, the 7.62mm SG 542 battle rifle and the 5.56mm SG 543 carbine, where both 5.56mm variants were designed for use with 5.56x45mm NATO M193 ammunition, while the SG 542—the full size 7.62x51mm NATO rifle cartridge.
