The body of the gun is quite tight. You don’t really have much room for routing the wires. Therefore, be extremely careful when pulling apart the receivers and putting them back together. It is QUITE EASY to break the wires. And you will experience a tiny bit of body flex after prolonged use under violence and frequent disassembly. If serious flexing does occur, you may consider installing a metal frame. CA has a metal frame designed for the AK47S and another one for the AK47 full stock.
When assembling the mechbox make sure you set the safety mechanism right on both sides. Make sure the gear positions are correct so that the switch plate can slide to your desired select fire position. Test this out before you plug the mechbox back into the lower receiver.
