- "Short range assault rifle, with low to medium stopping power depending on the caliber."
— In-game description
Situations and Terrorist HuntEdit
The SIG SG 556 is a derivative of the SIG SG 550 assault rifle and is the latest generation of the rifle series. The SIG SG 556 is a semi-automatic rifle manufactured by Swiss Arms AG that chambers the 5.56x45mm NATO round.
In-game, the 556xi is suited for short-to-mid range engagements. While it's fire rate is nothing to shrug off at just below 700 RPM, it still leaves something to be desired in close range combat in comparison to faster firing weapons.
- In some stills, the 556xi is equipped with a Red Dot Sight or an ACOG Sight, a Compensator or a Muzzle Brake, and a Vertical Grip.
- Glaz is seen using a 556xi in first three videos (SAS, FBI, and GIGN) of the Inside Rainbow official trailers, switching to his official OTs-03 only in the last two videos. The 556xi in these videos has several in-dev features:
- The rifle uses the OTs-03 firing sound.
- Glaz's right hand is off the grip and the trigger.
- The model is slightly different; it has more segments on the railed handguard and uses R4-C-styled diamond iron sights.
