Just to pass on a story that has recently happened to me. I no longer bow hunt and had 2 bows waisting away in my closet so I put them up for trade. I traded them for a Vortex Viper PST FFP MRAD 4-16x50 that was in decent shape. This optic would be my 5th from Vortex. Once I received the scope I decided to send it back to get it checked out. To my surprise they said the body of the scope was crushed due to either over tightening of the rings or impact. Before I sent it I could not tell from the naked eye that is was crushed. I sent it on a Monday. Saturday my wife received a package from Vortex. I told her to open the box and send me a picture of the work order since I work offshore. She messages me back saying, they sent you a new scope. Sure enough a brand new scope. Even told me the correct torque on the rings which is 16-18 in/LBS. What a great service department and I will continue to buy from them now on. Good to see businesses still putting their customer first.
