its for a long side rail mount.Is the scope in the box possibly a spotter or artillery ranging scope? Without rings, I do not see a sniper being able to put that scope onto a rifle during a firefight. Also, look at the distance between adjusting turret and front(?) end - almost impossible to visualize how a pair of rings would be used on it, on a K98 rifle. Appears to be made to live in that metal box, so must have been carried like that.
