This sniper rifle has the same zoom factor as the Deliverator; and is presumed to be the predecessor of the late Snap Shot, since they both have a blistering rate of fire and low damage output. The Snap Shot has since been removed from the shop in the v4.3.9 update for unknown reasons. Its scheduled return date to the UberStrike shop is uncertain.
The G3SG1 comes in Classic, Black and Camo variations. Only available for credits.
