A paintball gun (also known as paintball marker) is used to mark opposing players with paint. It uses air (carbon dioxide) to force the paintball out of the barrel at the speed of about 300 feet per second. This will cause paintballs to break upon hitting somebody but will only cause mild bruising to a person. This could blind a person, though, thus making it a necessity to wear a face mask or eye protection such as goggles.
There are four types of paintball guns and they are classified according to their firing modes. These are pump action guns, semi-automatic guns, fully automatic guns and ramping-mode guns.
In the early days of paintball, all guns were pump action. Each shot would require the person wanting to shoot to manually pull back the bolt to let a paintball fall in front of it and then manually push forward the bolt to bring the paintball in the position to fire. This was excruciatingly slow when compared to other firing modes used today, but is loved by many people as it teaches the importance of a persons skill with his gun.
Semi-automatic guns were designed so that when the trigger is pushed down, a shot will be fired and the bolt moves back...
