Last month I bought what I thought was a great deal on a mark 4. I called leupold to order turrets and that is when I discovered that it had a green illumination setting. Along with no real serial number. The police department I went to file the case with came with me to the shop where I had dropped the scope off to be looked at. After some mild drama the scope was handed over to the police and after a phone call this evening from the police it has been confiscated leaving me with no scope and no refund. I will be at the gun store tomorrow when then open hopefully to receive a full refund and an apology. I even offered to just get store credit but we shall see. More to follow.
