I had an early T/C 45 Hawken that had the half cock notch broke. Sent it in and they replaced the whole rear of the lock. I couldn't get it to fit in the stock so I whittled on the stock a little - and destroyed the stock. Sent the whole mess back to Thompson Center and they returned my rifle with a new stock to me - free of charge. If you are trying to decide between Thompson and another brand, may this assist your decision
