Editing Spyder (section)

== Operating mechanism ==

The original Spyder uses an open-bolt, stacked-tube blowback operating system.

The upper tube contains the bolt, while the lower tube contains the striker and valve components.

When the trigger is pulled, the sear releases the spring-powered striker.

The striker moves forwards and opens the valve, releasing compressed gas to propel the paintball through the barrel.

A portion of the gas also forces the striker backwards, recocking the mechanism for the next shot.

This permits semiautomatic operation without manually operating a pump between shots.[1]

The design is mechanically related to the earlier F-1 Illustrator marker and other stacked-tube blowback systems.[3]

Spyder markers have been manufactured in configurations compatible with CO2, compressed air or both, depending on the model.
