Hey, whats up?
I need some help from all the airsoftaholics on this site if possible...
I am looking to upgrade my AK74m mainly for better accuracy in the bush.

1-How does one find out what stuff goes with what gun? Is it word of mouth or are there specs somewhere on the net?

2-How does one determine what upgrades are needed for a rifle/gun?
How does one know if when upgrading a spring, do you need new gears?

3-How does one determinewhat parts to upgrade for a desired outcome?

So many questions now that I have an AEG!

Thanks for taking the time!
