Abstract: The improved paintball loader and hopper is designed to allow a paintball player to load up to one hundred paintballs in just a few seconds without opening or closing the hopper or speed loader tube separately. After fitting the paintball gun with the improved hopper, the improved loader is then lined up with the rails on the hopper and pushed forward to engage the stop on the hopper which opens the loader gate as the loader is pushed forward. At the same time, the loader rails engage the hopper gate and push it open beneath the loader's open gate. The paintballs in the loader fall into the hopper and the loader is pulled back and disengaged from the hopper which allows the rubber bands on the gates to pull the gates into the closed position.
