I have experience with both Knight and T/C on warranty work. Both are excellent.I broke my ram rod . I called Knight in a few days I had a replacement free of charge. T/C has replaced my old Renegade stock. It cracked. I was asked to send the stripped down stock.In about 10 days I had a completely new Renegade less the barrel and ramrod.I have T/C Fiber Optic sights on both the Knight Disc and Renegade. The front sites fiber optic broke. No questions asked I was send free replacements.IMO T/C' s warranty is second to none.
