The 556 semi has a two position gas piston operating rod system mated with a 1-in-9 twist barrel and a two-stage trigger
The SIG 556 features a 16 military grade cold hammer forged barrel with The barrel is locked to the steel receiver through a unique system that allows the user to easily change out the barrel.
The forearm housing the gas operating system is a vented non-slip polymer featuring the SIG TriRail design with three integrated Picatinny rails for mounting accessories. There is a forward mount for right or left side sling attachment. The flip up front combat sight is adjustable for windage and elevation.
The Picatinny rail equipped receiver is made of high strength carbon steel with a durable wear-resistant Nitron® X rifle finish. The trigger housing is made from a heat treated aircraft grade aluminum alloy with a hard-coat anodized finish designed to survive extreme conditions. The rifle comes equipped with a smooth two-stage trigger.
The SIG 556 also features an ambidextrous safety and is designed to accept standard AR magazines. A 30-round polymer magazine is supplied with each rifle.
Spare battery compartments are provided in the ergonomically designed pistol grip as well as the rubber padded watertight adjustable butt stock. The butt stock also offers sling attachment points. In addition to the standard model SIG 556 which will begin to ship in late summer of 2006, SIGARMS will also offer a SIG 556 L featuring a longer forearm but also equipped with the 16 barrel. The 556 L will be ideal for upgrading to the 20 barrel for more precision oriented shooting.
The third model planned to 2006 is the SIG 556 SWAT. The SWAT model will feature the same compact design of the standard SIG 556 with 16 barrel but will feature a flat top Picatinny railed receiver and a tactical quad rail.
These three rifles are the first of several new SIG 556 models that are currently in development at SIGARMS. The wait is over. The new U.S. made SIG 556 begins shipping in late summer - because the time has come.
Delivery info- we expect deliveries to begin on the 'standard' model in August 2006. Sig Arms 556 $1,299.99

Cool but maybe wait until FN has a civilan version of the SCAR rifle. I hear there is a distinct possiblility it will happen. FN already put out a version of the P-90 (PS-90)for the civilian market. It's pretty exotic but ammo will set you back about .50 cents per round.
