The paintballs are stored in a compartment that consists only of a plastic holding container and a lid. The hopper is connected to the body of the gun by a feed tube, which is only wide enough to allow one ball at a time to drop down in front of the bolt. The sides of the hopper are all sloped so that balls naturally slide down to the area where the feeder tube is. Although the simple design and the cheap materials used for gravity feed hoppers make them the most inexpensive form of hopper out there, they do have several disadvantages. The first is that balls tend to get stuck in groups that jam up at the top of the tube. Although this problem can be taken care of by shaking the gun about, thus breaking up the group and allowing the ball to fall down the...
