how can i get to 500 fps?
i own a classic army m24 socom sniper military type airsoft rifle. it shoots 313.5 fps right now. i heard that i can upgrade the fps to get it to 500 fps. I was wondering what type of spring i would need to get it there. would a 190% spring be enough? if not please direct me in the right path. thanks
