The FAMAE SG 540-1 and SG 542-1 rifles are gas operated, rotating bolt battle rifles developed by Schweizerische Industrie Gesellschaft (SIG). The rifles are built in Chile for the Chilean military. SIG designers used a long-stroke piston-driven action (with the recoil spring wrapped around the piston rod itself) and a 3 position adjustable gas regulator. The firearm is locked into battery by means of a rotating bolt which features two massive steel locking lugs. The receiver is made from steel and has two major parts, upper and lower, which are connected by pushpins. Rear sights are diopter drum-style sights.
