I purchased my TC black diamond last December used from a local sporting goods store. It is in great shape with the exception of the receiver end cap. It looks like somebody had it on too tight and then used too small a screwdriver to try to get it off. Well I called TC this morning and said I would like to order one. The representative said she would just send me one free of charge. I was sure surprised. Well, I just thought I would let everyone know about it since customer service like that is so rare these days.

PS I have only been putting that cap on finger tight. I don't know why it would have to be any tighter than that
