I was wondering if it would be possible to have a sticky post made in this area to post all kind of guides and resources to learn about airsoft internals? I've tried looking through all the posts but it seems like there's no centralized information regarding this material.

I've checked online a little, found Mechbox.com but they're down until January. Maybe everyone could post some websites they know and we could put some structure to it?

Thank you

I've been trying to open my king arms m4a1 but I've encountered a problem. When trying to separate the upper part of the body from the lower receiver, it won't move. Without forcing too much, I've tried lifting it off and sliding it off. Sliding it allows it to budge a little, but it still locks where as lifting it won't move anything.

I've taken off the stock, the push pin for the mag, handguard and both lower receiver pins.

I've been following this video http://www.youtube.com/watch?v=vZBGyMQ6lK0
