They are usually very easy to disassemble. The o-rings should be replaced as needed. They should be cleaned and oiled after every few uses (ideally after every use). Mechanical markers are typically quite reliable and need little in terms of regular maintenance. Here, we will discuss the most common and most readily available blowback mechanical guns. They range from basic plastic pumps to precision-milled guns that cost over a thousand dollars. There are many different types of mechanical guns that come in many different price ranges. The name "blowback" comes from the fact that air blows the bolt back into position. The bolt is forced back to its original position by the force of the air expanding. Once the ball is in the barrel, the bolt strikes a pin, opening the valve, allowing air to go down the barrel. These fire when the pulled trigger releases a bolt which is propelled forward by a spring and pushes the paintball into the barrel. Most semi-automatic mechanical paintball guns are blowback guns.
