How Mechanical Paintball Guns Work
A paintball gun requires the synchronization of a handful of parts in order to fire a paintball successfully. The first part is the bolt, which is the part on the inside of the gun that physically does the action of firing the paintball. The second is the trigger. The trigger allows the release of the bolt in order for it to fire forward. Then there is the gas canister, which provides the gun with the pressure and gas to fire the paintball. With a mechanical paintball gun it is generally carbon dioxide, or CO2. And finally, the barrel is what allows the paintball to fly as straight as possible.
The Firing Process
All of the parts have to fire and release at the appropriate time in order to fire the paintball properly. At first, the user has to cock back the barrel, usually with the tiny rod on the top or on the side. Once the barrel is cocked, the paintball falls into the chamber. The trigger releases the bolt, at the same time releasing a tiny bit of gas through the front of the bolt. The air and the bolt fire the paintball at about 220 to 300 feet per second, depending on the settings. After the paintball is fired, some more gas helps replace the bolt so that you can fire another paintball without having to cock the barrel again.
