I forgot the battery is housed in the stock (facepalm) I tried to fix the wobble in my stock and ended up ripping the battery wiring out in the process (facepalm) not having a good morning lol.
You cant put a traingle folding stock on a standard fixed stock AK74, the receiver is different. So either buy a new receiver, which for the price of them you may as well buy a new gun or an alternative would be the Romanian/East German style side folding stock which will fit a normal fixed stock receiver.
