I realize off the bat that there are some problems with this. Until I do a brass barrel, any extra power will probably just cause inaccuracy, and of course the cocking mechanism will have to remain in place in order to chamber darts. Now of course I COULD just use a backpack air compressor, but firstly I'm a cheapskate, and secondly I want this gun to be A: self contained and B: completely ridiculous (in an unusual way).
Note: drum mag and raider stock are going to be on the gun, perhaps with a laser sight if it is ever warranted.
So, the idea. The idea is actually mostly for a custom air tank, on a gun which doesn't come with one. What I want to do is to start with a standard clear Nalgene bottle, and inside of it rig together 5 bladders made from some appropriate form of hose material. Through the center of the Nalgene (and the bladders) will run a cpvc pipe which will serve to ensure that the bladders don't stretch too out of shape when they expland, and to house the line which will, through some form of joint housed at the closed end of the bottle, connect to all of the bladders. An input shraeder valve could be located just outside the mouth of the bottle on the main compressed air line, and only the trigger and pressure release valve would need to be inside the gun. Am I right to assume that by using expanding bladders designed to exert relatively consistent PSI I could get away with slightly less pressure regulation? Would it be easy to rig and over pressure valve into this? Will that setup house enough air to fire 20 or so darts at ranges that would be difficult to achieve with the stock plunger assembly? Am I insane? What kind of tubing should I use for the bladders and the lines? Where can I find a part as weird as a 6 way intersection for those pressurized lines?
Sorry for asking so many questions there, but even just pointers would be good. I've read around as much as I can, but I don't have a ton of time, so if somebody could even point me just to another similar and modestly documented project that would be immensely helpful.
