Airsoft Rifle Information

The super-short SEALS issue SG-552 sports a very short foregrip with RIS rails for the attachment of various accessories. Doing away with the 3 round burst function as found on the SIG 550 and SIG 551, the SG-552 is capable of semi and full auto fire like most other AEGs. Metal parts include barrel, muzzle, and trigger. The foldable stock aids versatility in CQB situation while offering enough length to feel comfortable aiming from the shoulder with the stock out. The rifle has fully adjustable sights with a fold-away trigger guard. The functioning metal cocking handle reveals the hop adjustment. The 552 comes equipped with Tokyo Marui's EG1000 motor that provides a higher rate of fire to that of the older SG550 and SG551.

Real Steel Rifle Information

The SIG 550 is an assault rifle manufactured by SAN Swiss Arms (formerly SIGARMS) of Switzerland. It is considered to be one of the most accurate mass-produced assault rifles available. Standard features include an integral folding bipod and a folding stock. The rifle has an AK-47-type action.

It was developed as a competitor for the Swiss Army assault rifle contest of 1979 to 1980 and was derived from the previous SIG 540 and SIG 541 models. The SIG 550 won the competition in 1983 and was renamed the Sturmgewehr 90 in German ("Stgw 90") and F ass 90 (for Fusil d'assaut) in French among the Swiss Army service. However, due to financial constraints, large scale production only began in 1986. From then on, it gradually replaced the older SIG 510 ("F ass 57" of "Stgw 57"), which is now a rarity in active service.

The SIG 550 uses the Gw Pat.90 5.6 mm ammunition designed for nominal use at 300 metres [1]. It can use the latest 5.56 mm NATO-specification ammunition, with poorer performances (the nominal ammunition has a 7 centimetres dispertion at 300 metres). The rifle uses 20-round or 30-round magazines. The SIG 550 is accurate out to 400 metres without optics (600 metres with optics).

The SIG 551 carbine variant of this rifle has been adopted by various U.S. federal agencies because of its reliability and accuracy, as well as by Special Forces all over the world.

An interesting feature of all SIG 550/551/552 rifles are that they are all equipped with semi-transparent plastic magazines, which may be locked together in order to facilitate faster reloading. The muzzle also features a metallic piece whose dilatation indicates the temperature of the barrel.
