For Low and Mid cap magazines, they use a spring system to push the BB's into the top of the magazine. You load them using a speedloader. For high-cap magazines (also known as hi-capa, hi cap), they have a compartment that holds around 200-5000 BB's. The typical hi-cap magazine works with a winding wheel under the magazine that winds a coil that unwinds to push the BB's up into the gun. Hi-cap magazines aren't very good for stealth games, since they use a compartment to store BB's and the BB's rattle a lot.
