Something you could do is either create a pressure chamber in the RPG and have a battery operated aircompressor hooked up to it. You will need to obviously wait several seconds for the pressure to build again, but if you reload while it builds, then it might be about full by the time it is reloaded. Also, this method is a bit faster, though it uses actual combustion which it seems some people here disapprove of. The combustion method is for you to essentially make it work like a potato cannon and have a way to directly inject the fuel without breaching the barrel and create an electrical ignition system. I intend on eventually building an airsoft RPG along with hopefully some kind of artillery piece so I will post both when I get them up. Good luck!
