What’s the difference between pump, semi-automatic and ramping paintball guns?
A pump gun is a type of marker that must be manually re-cocked every time you shoot a ball. It is not like a BB gun that has to pumped up to shoot. A semi-auto gun re-cocks itself every time you pull and release the trigger (cycle one time). With ramping, once you pull the trigger three or four times the gun will auto fire until it reachs 15 balls per second.
