I may have finally rounded up the cash to throw an aimpoint on my AR, but I have a question. I have found a demo model from a retailer that he is letting go for deep discounts. He claims and I can pretty well see that it is in great condition, but the actual age of the optic is questionable. My question is, if an aimpoint is put in a box and forgot about for 5 years or so, could this degrade the optic in any way other than battery life? I wanna jump all over this deal, I just don't want to end up buying a relic that has more problems than a new one.
