Looks good, but maybe some properly sized pictures would be nice. :wink:

How heavy is that air tank?

EDIT: and where did you get a 5 gallon tank? Smallest I've found is 7 gallon.

Nicely done but such a relatively large chamber can't be good for efficiency, have you thought of welcoming detents into your life?

A regged down paintball tank could probably give you the same firing time in a lot more compact package.

Why such a long hose?

When I first saw that picture I thought it was a coaxial vortex. :P

When you make a stock, use the back end cap as a buttstock and use a trigger linkage to move the trigger and handle forward. That way, you can have a stock without making the gun longer!

Thanks to the internet, I know everything about everything exept how to actually do anything.

The best way to limit the rpm would be to add some kind of detent, you can look at one of JSR's impressive detent projects for reference (someone else will have to provide links, or use the search), or if you want a simpler (but less adjustable) detent method, check out my bbmg. I used a simple windshield wiper hose as my detent (mine works if you're using .177 bb's, but other tube sizes will work for 6mm bb's).
