Does anyone know if there is a quality difference between TC muzzle loading barrels (50 Cal) sold as a kit compared to a regular TC (non-kit) when sold as part of the rifle. I have a chance to buy a barrel with the following inscription "Thompson/Center Arms, Rochester New Hampshire Cal 50." The serial number is K4780, which I believe was once part of a kit by Thompson Center. It looks exactly like a Hawken barrel; however it does not state "Hawken" on the barrel. The guides for the ramrod are black? The blued finish on the barrel is good to excellent and bore looks to be in excellent condition. I could use some advise on this since I've just recently got back into muzzle loading shooting. In your opinion, is this barrel worth $90.00?
