How does a CO2 semi-auto paintball gun work?

Answer 1

Paintball guns fire spherical paint-filled balls by application of short bursts of rapidly expanding CO2 (Carbondioxide) gas. Upon disegage of the trigger mechanism, a slide is forced forward by means of a coil under tension, thus loading the paintball into the barrel. At it's final position, the slide opens a valve enabling the flow of gas. The gas forces the paintball down the barrel and accelarates it up to a speed of more or less 300 fps upon exit of the barrel. The backpressure of the shot causes the slide to return to it's original position, loading another paintball and engaging the trigger.

Answer 2

As with every paintball gun. When you pull the trigger, it sends a electronic pulse which sets off the bolt. The bolt pushed the paintball further down into the paintball gun. Were little rubber detend holds the ball in place, to stop is from rolling out the barrel. Then a squirt of Co2, No2 or HPA sends the ball flying out at an impressive 220 MPH.

Answer 3

You fill your gun with paint in the hopper. the CO2 or nitrogen tank pushes out "air" and forces a paintball through the barrel and at your opponent.
