This hopper is the latest in Tippmann innovation. New Bend Sensor Technology loads a ball only after a shot is fired giving you the reliability of a force fed hopper but extended battery life. Loading paint only after a ball passes out of the loader reduces jamming no next to never! This hopper is lightweight, inexpensive, and designed to fit on any standard feedneck without sanding. The low profile and aerodynamic design keep your hopper hits to a minimum, but will not enable you to fly like a bird.
