You can't sell a gun on ebay. So, they get around it by taking the barrel off the stock. The lock is in the stock. So, you pay $200 for the barrel and find the same buyer selling a stock and pay $200 for for the stock with the lock and trigger in it. You just bought a TC Hawken for $400 that you know nothing about.
Buy Leatherbarks gun. No stock TC will shoot as good even if it's brand new.
