Question on Indoor CQB Spring (<360fps)

Hi all,

I'm totally new to airsoft, and I recently got my first aeg, a kwa m4a1, which shoots about 390-400fps stock. I'm looking to swap the spring to M90/M95 to lower the fps to game legal (<360fps). Will be running 7.4v 25C Lipo. But have a few questions:

1) Any standard spring on the market would be compatible with KWA M4?
2) Is there anything else I need to modify/change if I load the M90/M95 spring in?
3) Anything else I should do/consider to prep this stock aeg for gaming?

Thanks very much!
