Developed for the Swiss Army, the SG 550 5.56mm assault rifle was introduced into service in 1990. It has evolved into a modular family and also includes the SG 551 carbine and SG 553 compact commando variants. The series uses an indirect gas operating system with a rotating bolt. All models have a folding stock and trigger guard, and the SG 550 can be fitted with a detachable folding
bipod.
