Just put a spring from my old AUG into my WELL D98 Thompson... its only a plastic gearbox... and the old spring might be 250-300fps better than the original which ended up being 120FPS

not much of a result.. the fps ended up being the same old worn out spring maybe? limitations on plastic gearboxes?
