Rather buy a brand new £130 Metal CYMA AK from TaiwanGun, throw £100 of parts at it (Motor, hop bucking, MOSFET etc) and end up with a gun that performs the same, if not better. Then I would use the £170 to buy another CYMA AK as a backup gun (because why not?), and still have some money left over.
I love this bit: The guns lever has been welded back on and dip coated. Doesn’t effect guns play.
