he Swiss-built SG 553 is manufactured around the SG 551/552-series gas piston action and features an adjustable two-position gas piston system, ambidextrous controls and a hooded front sight.
"The classic SG rifle series are highly sought among collectors and firearms experts," said Jeff Creamer, SIG Sauer executive director and general merchandise manager. "This was a unique opportunity and the only time SIG Sauer has been able to offer the SG 553 to the commercial market in the United States."
The SG 553 is chambered in 5.56x45mm NATO and is available with either the famous Swiss Rotary Diopter Sight welded to the receiver or with a Picatinny rail for mounting optics or accessories. Flip-up sights come standard on the railed models, while all models come nitride finished for enhanced durability.
The SG 553 pistol also incorporates a Swiss-style polymer handguard, translucent polymer 30-round Swiss magazines and a three-prong flash-hider. It has a barrel length of 8.9 inches, an overall (extended) length of 20.2 inches and a weight of 5.9 pounds without a magazine.
