In most images I see, both the spotter and the sniper carry sniper rifles. Both generally have sidearms, and their knives.
Logic would dictate that the sniper carries the sniper rifle, whatever it may be, and the spotter carries a battle/assault rifle. (Yes, there is a difference.) Generally, the spotter would carry one of the shortened rifles, assuming his nation's military had them - M-4A1, C-8, AKS-74M, et cetera.
