The SG 550 is a selective-fire 5.56×45mm NATO assault rifle firing from a closed bolt. Design details Operating mechanism SG 550 disassembled into its main constituent groups Over 600,000 rifles have been delivered since then and production for the military has now ceased. Production began in 1986 and four years later the rifle was officially accepted into service in 1990, hence the military designation Stgw 90. In February 1983, the decision to adopt the SG 541 was publicly announced (the designation of the rifle was changed in October of the following year to SG 550, while the carbine version became known as the SG 551). The C42 by Waffenfabrik Bern, 6.45mm Rifle version Production In 1981, the experimental 6.45mm GP 80 cartridge was rejected in favor of the more conventional SIG 5.6×45mm Gw Pat 90 round (with a 4.1 g, tombac-jacketed, lead core projectile) that is the Swiss equivalent to NATO's standard 5.56×45mm cartridge. The solicitation was narrowed down to two designs: the W+F C42 (developed by the state-owned Waffenfabrik Bern, using both 6.45×48mm and 5.56×45mm cartridges) and the SG 541 (developed by SIG using the SG 540 as the basis for the SG 541 prototype). Another aim was to reduce the overall weight of the rifle while retaining comparable or improved accuracy out to 300 m. Emphasis was placed on modularity the weapon family was to include several variants of the base design, including a compact carbine that would be issued to rear-echelon and support troops, command staff, vehicle crews, special forces personnel and paratroopers. In 1978, the Swiss armed forces formulated requirements for a successor to the Stgw 57 battle rifle (known commercially as the SG 510) using the 7.5×55mm GP 11 cartridge. The rifle is based on the earlier 5.56×45mm NATO SIG SG 540.
