Simple. Bevbor has all his weapons at 1:1 scale, with the exception of the brute shot. Take the length on halopedia, divide by 86. Take that number, times it by your height (in inches) and input that length in the full model. The scale factor will change, and copy and paste that scale factor to EACh part, and it will be proportional to you as a 1:1 brute shot will be to the META. I've been tempted to pep it myself, though I'm insane and want to do it full-sized...
