A player normally gets a semi-auto or a pump after their stock gun. Pumps offer more accuracy, and waste less paint and gas. They are also less expensive. Semi-autos shoot a lot of paint, and use more gas than a pump. You will also spend more on a semi-auto. Both of these guns shoot with large capacity gas bottles, at adjustable speeds. Electric markers are the ultimate gun, shooting a lot of paint fast, and more accurately. All are semi-auto, and most can be adjusted to shoot full-auto, and two or three round bursts. These guns shoot all air, and will cost a lot of money. Pneumatic guns are relatively new in the sport. They have almost no internal parts, so are easier to clean and repair. When the gun shoots, it propels the ball forward, while making the barrel move forward, which allows another ball to enter the breach. The guns are fairly fast, but are expensive. There are some other oddball guns, such as double-barreled pumps, military style paintguns, and even guns that fire a cartridge, like a rifle.There are many ways to upgrade or improve your gun. One of the best ways is to get an after-market barrel. A good barrel will make the gun more balanced, shoot more accurately, and become quieter. Barrels however can be very expensive. You can buy brass, aluminum, carbon and steel barrels with rifling, porting, and muzzle brakes to make the gun quieter and more accurate. Changing some internal and external parts on your gun will change performance too. Some more commonly changed parts are bolts, air adapters, regulators, expansion chambers, and low-pressure systems. Bolts allow the air to disperse better, which makes the gun more accurate and prevents some ball breakage. Some air adapters are bottomlines and remote systems. Bottomlines allow the gas bottle to mount horizontally on the handle of the gun. This balances the gun better, and gives you a stock. A remote system allows you to attach a hose to a bott...
