The stock fps on my P226 is 320 and on my M4 it's 430(both with .20's). I couldn't find the club fps limit but I had thought I saw it somewhere here @ 400 for AR's.
As an aside, I found an app for any iOS touch device that will calculate joules/mps/flight distance dependant on your bb and fps. etc when you input your fps. That one's called simply AisoftApp. There's also one that calculates battery charge time called ASG Calc. just thought I'd throw those out there.
