Had my mind dead set on snowchecking an orange 163. After talking to a couple other guys they claim they are bending the rails when riding back home, ND (ditchbanging). Heres my questions #1. How much easier (if at all) are these rails going to bend than a 155 #2. As far as i know the only thing the assault has different than the pro rmk on the rails is a simple bolt on brace? Correct? Can i add this to my 163 and eliminate my worries?
