Restoring a 12+ year old King Arms AR AEG

I had this sitting in my collection for years. The insides failed and needed rebuilding. Thankfully, King Arms has not changed much of its V2 gearbox specifications forever. To get a working trigger I dropped in a CYMA V2 microswitch. You are hearing the system with no lube.

Parts going in, 16:1 King Arms gear; King Arms tappet plate and selector plate; CYMA high torque motor; CYMA microswitch trigger board. More to do...
