The Proto Hopper line has gained a following with entry level and pump players. The Proto Hopper line brought back the basic paintball loaders with a small twist. The Proto hopper has a unique patented feeding ramp located right above the feed neck of the Proto Hopper. This allows the Proto Hopper to evenly feed paintballs from both the front and back of the loader. The Proto Primo hopper is a very light weight and inexpensive option for someone looking for reasonably priced hopper that still feeds at least 8 balls per second.
