guys I m building new gun with 3bands but some information is missing ,my previous 2 band slot giving me headache every time try to load them I mean arranging the band ,in picture below you can see my theory is to load the far band in the front to the third notch away from trigger so all band line uniform this mean thias band will go through or inside the 2 band I hope this clear but practically when you pull the band it will slide and kick all band in the slot and will be positioning in the first ! is this clear? so how to solve these ?
