However -- Pulling is going to gain a great deal of speed due to the volume needed to fill the cylinder is reduced. I understand you can gain the same speed pushing by introducing the exhaust from the solenoid back in with the input air -- have not tested it, but will tomorrow.

Or you can push with smaller cylinders

I worded my response earlier pretty poorly, I wasn't talking about the difference in speed/power between a cylinder going in or out. I was merely making a point about using a lever to account for the slower speed of pneumatic cylinders as opposed to elastics or springs. The ri3d and several other places that said pneumatics don't work for shooting since they aren't fast enough were either placing the cylinders to far from the fulcrum or trying a punch, where the slower speed is a huge problem.

Here's the intake system, as requested;
