AK disassembly prob.
 

I'm trying to get the gearbox outta my kraken, and the little round part where the selector switch was keeps bringing up in the body. How am I supposed to get it out?

nevermind, I just broke the shit out of the plastic body. It came out fine then.

Thats one way to do it I guess, if you mean the little spacer they has flat edges on it that matches up with the lever. It just lifts out, sometimes it gets stuck on there with the thread lock they use.
