Paintball Marker
A Paintball Marker is the primary piece of equipment used
in paintball to tag an opposing player. An expanding gas forces a paintball
through the barrel at a muzzle velocity of approximately 300ft/s (90m/s).
This velocity is sufficient for most paintballs to break upon impact
at a distance, but not so fast as to cause tissue damage beyond mild
bruising. Nearly every commercial field has, and strictly enforces,
a rule limiting the muzzle velocity of a paintball at or below 300ft/s.
The most technologically advanced Paintball Marker is the electro pneumatic.
Here, the trigger activates an electronic micro switch and information
is passed to a computer-controlled solenoid valve which releases the
propellant to drive the bolt forward and fire the paintball. This microcontroller
operation makes the marker operate very quickly, and allows for extremely
high rates of fire. These markers are the most expensive and are generally
used for tournament play where rates of fire can reach and exceed 30
balls per second.
There is also a strong following of stock-class and "pump"
players who use Paintball Markers with a purposefully low rate of fire
and ammo capacity. Pump markers require the player to re-cock or "pump"
the marker before each shot, and stock-class markers have even more
limitations on rate of fire and paintball capacity. Some markers are
designed to look like real guns. These markers are called mil-sim, short
for military simulation. They are used almost exclusively in woodsball
and military scenario games, though with a few modifications the markers
can be competitive in the speedball arena.
