SIG MG 710-3
The SIG MG 710-3 is a Swiss 7.62 mm general-purpose machine gun (GPMG) designed and manufactured by SIG - Schweizerische Industrie Gesellschaft (currently Swiss Arms AG). The weapon was developed as a commercial venture primarily for export, since the Swiss Army had already adopted the 7.5 mm MG 51 GPMG (chambered for the 7.5×55mm Swiss Schmidt–Rubin rifle cartridge), produced by the federal arms factory W+F. == Development == Work on the SIG MG 710-3 machine gun (initially designated the Model 55, changed in 1957 to SIG MG 710) began in 1955 and its design was influenced by the MG 45, a late World War II development of the German MG 42 machine gun.
