I have a second generation red dot sight from Tactical Archery Systems. This is the four dot model with the permanent green triangle on the lens. The sight was purchased the week after Christmas and used on my bow for five or six shoots. I decided to go back to my HHA single pin sight as the multiple pin was getting frustrating for me as I have always shot a single pin adjustable. This sight uses no batteries, it is run strictly off the light that the fiber optic cable collects. The sight is in really good shape, not damage to the sight. Save your money and buy this sight over a new one. I am looking for $100 shipped to your door. Please do not make any offers or request trades as I am not looking for anything under $100 or any new gear.
