Semi/Auto BB gun

As my first pneumatic is mostly finished , I feel its time to move on to another project using the knowledge I have now gained from my first ever build. Id like to build a 6mm BB gun which would consist of a Pressure washer valve , Reg'd 850psi paintball tank, 8mm tee magazine and a 16" 6mm steel barrel. As I already have a blowgun valve, I will use that as a temp valve before replacing with the pressure washer valve.

Mostly inspired by JSRs 9mm smg http://www.spudfiles.com/forums/9mm-smg ... 19367.html

but, when you have options withn that 850psi.... MAKE IT 10 MM

I could, as i would actually get more fps with a bigger calibre according to ggdt. But It wouldn't work to its full potential because im not using a qev?

GGDT estimates 650-700fps with 1.1g 6mm steel ball at 400psi :3

I thought this might be suitable for my uses?

What kind of flow could I expect from one? Can they be modified?

the eBay listing stats 25l/min max but that water i would think air flows much faster.
