The gun that brought ICC into the market. One of the first assault-Shotguns available to the public, the SB21 (StormBringer) caught the world's eye and even BigBurger Inc. stood up and took notice (the BigBurger Inc. WCAA is a refined version of the SB21). The Pale Winter Green has got 3 pairs of two-tone Nano Martinets, rear-mounted Spheric Nano rack, flake tubing, and all-over use of Notum alloys. It also uses the Repository OptoCoat.
