excalibur needs to get the word out on who repairs or has parts for there stuff. i called excalibur direct and they told me to look in a hardware store. nice ? i then asked for the size thread of the bolt and they couldnt even tell me that. im not sending my bow in for a rounded screw. i just think its odd they dont have a box of every screw that is in there xbows since there all basically the same just laying around. probably cost a 5 cents. danny miller doesnt have a website. i find that strange for a company that is one the bigger in crossbows. guess what? i just put the nasty screw back in and lived with it for now.
