Gauss reflex sight is a weapon mod for the Gauss rifle in Fallout 76.


When applied to a Gauss rifle, the mod decreases AP cost, sighted transition speed, and sighted weapon spread (thereby increasing accuracy). The sight uses a holographic green circle and slightly increases magnification while aiming.
