Firing Cycle (General Sequence)

The firing cycle represents the recurring operational sequence that occurs each time a paintball marker produces a shot. In a general description, the cycle begins when an actuation event is triggered, either by a mechanical linkage (such as a sear release) or by an electronic signal sent to a solenoid. This event initiates movement in the bolt or related components that position a paintball in the breech and create a seal between the firing chamber and the barrel.

When the breech is sealed, a valve opens for a controlled interval, allowing compressed gas to flow from the regulated supply toward the paintball. The gas accelerates the ball down the barrel, after which the valve closes again. Following the gas release, internal forces such as spring tension, pneumatic return, or electronically managed air pulses return the bolt and valve components to their resting positions. At the end of the cycle, the marker is in a state where another paintball can be loaded and the sequence can repeat.

The timing and duration of each stage affect several observable characteristics. Factors such as how long the valve remains open, how quickly the bolt moves, and the relationship between operating pressure and gas volume are associated with rate of fire, gas efficiency, and velocity consistency within the marker’s designed limits. Differences between platforms arise from how designers balance these parameters rather than from changes to the basic sequence itself.

Mechanical and electronic markers implement the same fundamental cycle through different means of control. Mechanical designs rely on physical interactions between springs, levers, and air passages. Electronic designs add circuit boards, timing logic, and solenoids, providing more options for adjusting how long valves stay open or how quickly components move. Regardless of approach, the firing cycle remains the core mechanical pattern that defines how a marker progresses from a ready state, through a shot, and back to readiness.
