Yes.Will FN warranty a second hand purchase?
http://fnforum.net/forums/fn-five-seven/26886-contact-customer-service.htmlI email FN several days ago about the bad weld and asked what I needed to do to get replacement. They have not responded. Is it normal for them to take a long time to respond.
That is correct.Browning service Dept. ONE BROWNING PLACE Arnold MO 63010
