=== Closed-bolt operation ===

In a closed-bolt marker, the paintball is chambered before the firing mechanism is activated.

The bolt remains forward when the marker is ready to fire.

When the trigger is pulled, the hammer strikes the valve.

Gas released through the valve propels the paintball through the barrel.

The pneumatic system then opens the bolt, recocks the hammer and prepares the marker for the next shot.

The bolt returns to its closed position before the next firing cycle.
