Well, if it's the first Win 1000, the one made in Turkey, you may be out of luck. Daisy has cut ties to Hatsan and may no longer have a parts supply for those guns. If I were you I move on and look for another gun. Those Daisy imports just keep getting worse. RWS sells some decent rifles, Crosman now has a halfway decent spring rifle lineup, or if you don't mind a little do-it-yourself stuff theres a number of cheaper Chinese guns that do pretty well with a bit of tuning.
