TC really stands behind their products!! I have a Thompson Center Hawken flintlock rifle that is 37 years old and last year the main spring broke and I couldn't cock it. I contacted TC and the person I spoke to said to send the whole mechanism in to the service dept and within a week I had a brand new mechanism installed on my rifle at no cost. When they say lifetime warranty they mean lifetime warranty. When it comes to anything blackpowder I am buying TC!!
