hate to burst your bubble. this is what i found on excaliburs web site.http://www.excaliburcrossbow.com/content/contact i called and got told to go to a hardware store direct from the company. what a joke. the person never even mentioned danny miller for repairs in the usa. if excalibur had a link to danny miller or even an explaination of what to do on there website page i wouldnt be writing this. its almost like a secret club and your not in the know if you dont know danny miller. just telling my story as it happened. to tell you the truth danny is a nice guy but very opinionated.just dont tell him you want an sts or fast flight string. you will get an hour long speech. not the kind of thing i want when its my crossbow that i want to fix up. im gonna call tomorrow to see how long it takes to get the screw. if he even has it.
