The SG/1 (scharfschützengewehr, "sharpshooting rifle) variant is modified from the G3 battle rifle. The rifles are individually selected from the production line for their accuracy and are then further modified and fitted with the Zeiss 1.5-6x variable power scope. Although primarily intended for sharpshooting purposes, it still has the ability to be fired fully auto.
In Back For Blood Special, this weapon was paired against the Spetsnaz Dragunov Sniper Rifle. While both weapons had high kill ratios, the Dragunov was deemed faster and more accurate in terms of execution and given the edge.
