My wife asked me to make sure her Excalibur Assassin was still sighted in. I had a new installed at the end of last season. I fired one arrow and the farking thing exploded!!!! I am pretty sure my right thumb is broken and my Oakleys have a huge scrape right in front of my left eye, deep enough I can feel it on the inside. The gadget that holds the string is gone, one of the limbs tips shattered and it bent where the limbs attach to the frame. No idea wtf happened, it has a dry fire block so definitely not that. Near as I can tell it just freaking blew up. ALWAYS WEAR EYE PROTECTION!!!!
