I have an old knight, but I believe TC has the same warrenty... Anyhow, mine rusted real bad when I was younger and I called knight. They said to send them the gun so I did, and they replaced the barrel free of charge, just shipping was paid. Knight and I believe TC have an awesome warrenty, just don't do it with a CVA because from what I understand they won't cover it. When they shipped the gun back there was a note that said "keep gun clean and oiled, should be no further problems". haha i learned my lesson
