the bleed button comes out when the gun is gassed up to prevent you from unscrewing the back cap when the gun is pressurized. it's a safety feature. once you remove your tank, you can press the bleed button to purge the system of any leftover air, or if you wait 5 or 10 minutes, the gun will do this itself, and possibly scare the crap out of anyone within 10 feet of you.
so basically, yes air does come out when you press the button with a tank attached, because they don't really want you to press the button. it should stick out when you're playing.
