Anyone have one? Just got the one I bought today and have the suspicion Midway sent me one that was previously returned. Box was basically open already (no plastic wrap or taped flap) and there were a few small scratches on the unit. Neither of those bothers me really, but I noticed the first five dot illumination settings do nothing...nada, zilch! Even with the front cap closed you won't see any hint of the dot until you get to the 6th setting and there's only 9 in total. Just curious if this is the norm for this model, if it's a sign of a weak battery, or if it's just flat-out defective. First Aimpoint so I'm in the dark here experience-wise.
