SIG SG 550

The SIG SG 550 is a Swiss-made rifle based on the earlier SIG SG 540 and designed to replace the SIG SG 510 battle rifle in Swiss service. A peculiarity of the rifle is its use of the SIG 5.6x45mm Gw Pat 90 cartridge as opposed to NATO's standard 5.56x45mm cartridge, albeit a later variant would be developed to use 5.56x45mm NATO ammunition. It is also known in Swiss service as the StGw 90 (Sturmgewehr 90) or Fass 90 (Fucile d'Assalto 90 or Fusil d'Assault 90).

= SIG SG 552 =
The SG 552 is the shortest version of the 550 family. Apart from the charging handle (round, steel), externally it appeared to be a shorter version of its bigger brothers, the SG 550 and 551. However, internally, the SG 552 featured several major differences: the gas piston was fixed to bolt (like on a classic AK-47) and the recoil spring was located behind the bolt (like on an MP5) instead of in the gas tube.
While SIG claims these changes were necessary for technical reasons on this extremely compact assault rifle, they led to certain reliability issues - unusual for the company. To address this, the SG 552 was updated, resulting in the SG 553.
The SIG SG 552 is also known as the Commando.

One of the latest generations of the SIG SG 550 rifle series is the SIG-Sauer SIG556 series. Due to import restrictions by the BATF, SIG built these rifles in the United States. They differ in that they have an aluminum lower receiver somewhat similar to the AR-15 designed to take STANAG Magazines and have a rail on the upper receiver amongst other cosmetic details. They are generally semi-auto only, though select-fire versions also exist for military and law enforcement.
