I'm not aware of any or the airgun manufacturers offering transferable warranties, and I think Daystates at three years is one of the best from a manufacturer for air guns - If I'm wrong please let me know - it would be a good thread to list all manufacturers and there respective warranties/terms. I think it's great that the Airgun centre offer a lifetime warranty to the end user - if it's worth the paper it's written on it is a great reason to buy from them?
