Dude call bowtech and tell them the problems your having.. BOWTECH is awesome about making there bows right. I had one the cam was wearing down in my serving where it goes on the cam. And they replaced string and cams yes cams plural...If its def the BOW and you havent put aftermarket strings on or modified the cams they will warranty 100% and as for the roller guard thats a warranty thing...that will be replaced no problem by them.
