Editing Pump paintball (section)

=== Open-class pump ===

'''Open-class pump''' permits greater flexibility in equipment configuration while retaining the requirement for manual pumping between shots.

Depending on the competition, players may use:

* Gravity-fed or electronic paintball loaders.
* Conventional compressed-air or CO2 cylinders.
* Vertical, horizontal or other permitted feeding arrangements.
* Pump markers incorporating aftermarket components and modifications.

Open-class pump rules generally prohibit mechanisms that automatically recock the marker.

The Stock-Class Paintball Network published tournament rules allowing manually operated pump markers with conventional air systems and different loader configurations.[9]
