Pump Gun - Pump Guns - Pumpguns
Pump Guns were the first type of paintball marker that was used in the first paintball games. Pump guns require a pump action to fire, meaning that the gun must be pumped before each paintball is fired. In contrast, semi-automat markers like the PM6 from Dye can be fired as many times as the operator pulls the trigger. Because of the pump requirement, a player is limited to how many paintballs he can shoot per second, maybe two or three. In contrast, makers like the A-Bomb Intimidator by Bob Long can shoot as many as 25 balls per second. There are other technological differences between the Pump Guns and the semi-automatics that players must account for in games. Hoppers for semi-automatics can hold up to 290 rounds of paint, while pump guns can usually hold a maximum of 20 paintballs. This means that while the pump guns player is refilling his gun, the semi-automatic player can keep on shooting.
Another difference between Pump Guns and semi-automatics is the airpower for the two machines. While semi-automatics like the Nasty Typhoon from Palmers Pursuit Shop can come equipped with CO2 tanks, Pump Guns are powered by 12 gram carbon dioxide powerlets. This means that the Pump guns player must frequently replace his air power from one powerlet to another during games. Another drawback to Pump Guns is that the marker must hold paintballs in a linear feed tube parallel to the barrel.
The technology of the Pump Gun. One of the main differences between the pump action and semi-automatic marker is the bolt mechanism of the gun. In a semi-automatic marker like the Hybrid Autococker from Powerlyte, the bolt moves between the firing and loading position automatically after each shot. In contrast, stock class or pump guns require a manual cocking mechanism. After a shot is fired, the pump handle that is attached to the cocking mechanism is manually pulled back to allow the next paintball to fall into the marker. Once the paintball is in the marker, the bolt and paintball are pushed forward into the chamber. This pump guns technology requires 2 manipulations of the marker before it is ready to fire again.
Another limitation mentioned in this chapter is the air supply that powers the different markers. In the semi-automatic, the power supply is often CO2 of High pressure air in tanks such as the Crossfire Air System. These tanks are usually connected onto the back of the marker, and allow the player to fire up to 1,000 paintballs. The pump gun is powered by 12 gram CO2 powerlets that can usually fire a maximum of 29 paintballs. At around the 29th shot fired, the player must replace the powerlet on the marker with a new one.
There are still markers available that use the Pump Guns or stock class technology. For a reliable pump gun, you should test out the Blade from Brass Eagle.
The Blade is constructed with a vertical feed post, and an anti-double pump design that prevents overloading. Markers like the blade are less expensive than semi-automatic markers, and they are easier to maintain than the high end electronic markers. Other fun pump guns include the Maverick from ACI, that is loaded with a precision honed barrel.
