ive had mine on three different bows as well but i used thicker arrows in the past so i had to super glue some stuff in the spots where the arrows go. i used the stuff that they line cabinets with cut two thing strips (just a little thicker then the width of the rubber) glued it to the side then glued each round spot and put an old arrow in to press the glue and liner into place and let each one dry all the way across. my arrows dont even move now.
