Nikon scope

[TIGGREM2]

Got a Nikon scope on my t/c encore and it won't hold zero. Tried many times to get it sighted properly but just doesn't hold zero Its a 3x9x50 mm pro staff . Has any body used there no fault warranty ? I was reading the repair instructions and it's got to be original owner and you need proof of purchase . I don't keep up on paper work like that and bought it mounted to my gun . The set up is a few yrs old

I have owned 2 of their Prostaff scopes and both had to be sent back for not holding zero on mild recoiling rifles. Their warranty dept was easy to deal with and the turn around time wasn't bad at all. They came back with a note about broken erector springs and I sold them both without ever messing with them again.
