Hey thundercactus, just so I know a little more about the system. When you say to get the most out of the cylinder I’m guessing that your meaning that the porting helps get the allow the correct amount of air to be pushed out of the cylinder to propel the bb out of the barrel but not too much that a lot of air is pushed out after the bb leaves the barrel. So if the red cylinder is rated at 500 fps and is sent out with these short barreled guns this over volumed problem should be even worse at 500 fps with even more air wasted and piston impact. What I am getting at is there anything detrimental with running an overvolumed ptw?
