Ok so i just got basically all the externals to make an ak-47 (except a firing selector switch), as far as i know i still need the gearbox, motor, and battery tray, I am not knowledgeable in internal parts and have no idea what else i need? (cylinder head? spring guide? other things?) if I am missing anything let me know also if u can recommend a particular gearbox or other parts im glad to hear it.
