Keep in mind that this sport is also plagued with 12 year olds who spout off crap or themselves believe in things like melded springs or other ridiculous crap like how some guns can break the laws of physics (AEG vs GBBR vs PTW vs Polar Star) or can't seem to grasp the concept of how mass, velocity, and energy interact with each other.

The only other thing I can add here is Airsoft Mechanics is a great site. Don't post there, just read and if you do need to post, have a well researched question. It's a goldmine of good information.

But like Styrak said, G&G's are good out of the box and ideally you shouldn't be messing with the internals unless you really know what you're doing, and you should figure out what the OEM baseline performance is before you mess around with things, but if you've dealt with fixing up MX bikes this should be a cakewalk.
