For sale - an EOTech 552.A65 made in roughly 2008. It is used, but barely. It has spent most of its life in the factory box and and spent one session at the range on my rifle. There is one scuff on the forward left corner that won't even show up in a picture, but I wanted to disclose it. It is night-vision compatiable and operates on two AA batteries. $350 shipped and insured. PM me with questions. I will take paypal plus 2%.
