My point really is that not only the pressure, but the release of air is a huge part of the effectiveness. even with longer barrel there will be a VERY noticeable difference in performance, it really doesn't take much to push a nerf out a barrel, and compared to a burst disk (totally impractiical, but the best)or a piston valve, the ball valve will let much lles air actually push the dart. Just letting you guys know that people have broken the sound barrier with guns like these, only difference is higher pressures, and you to actually get past moch 1 you cant use air, because its expansion rate is too slow.
Im not sure about the material but it is most likely a few layers of aluminum foil.
@itvellis a burst disk will open to any diameter that your union joint it is so It will dump the most air possible into the barrel when it ruptures. the ultimate limit of air flow is your barrel, so if your valve can open to the full diameter of the barrel the only possible way to increase performance is to make the valve open faster, and a burst disk even surpasses a well made piston valve in speed of opening completely.
It was shot with no ammo, buy this beast Heres all the details
