a couple of years back i got to half draw on a 170 180 inch buck and my release went of and it woulnt never lock down after that sent it in and true fire said it was due to currosion on the inside and it was junk and they would replace the jaws and internial componits for me , so i know i dont need to but i just do it every year . shot of a lifetime blown due to neglect wont let it happen agian
