Thanks for your responses. I re-read the thread you linked me, and it's all coming together. I should have read it thoroughly, the first time. I feel so stupid.
And, now I see that my idea isn't revolutionary, nor is it even unheard of. And that's good, because I know it has been tested, and it works.
Basically, the norm is to match the volume of the barrel, to the volume of air being compressed in the cylinder, it'll be alright? That way, the piston head will most likely hit, right as the BB is leaving the barrel, thus maximizing the velocity?
If that's all I need to do, then consider me a happy man. Thanks for your time, everyone. My question has been answered.

400% pushes an airsoft BB well above sane safety levels.
If it comes above the 500fps/whatever Joules, you are manufacturing a firearm without a legal permit to do so. That means serious jail time.

Agreed, but I want to test with the absolute most power the weapon can handle. As to test the parts, and endurance of the design. I'll bump it down to legal, when I play. 250% - 300% of the same model; however, remember that this is a sniper rifle, so the fps is staying at about 500.
