I just got a used and very cheap AK. I want to upgrade the internals of the gun with better ones but are there any parts that are from a V.2 gearbox that will work in a V.3 gearbox because I have a almost new spare gearbox from an M4 that I have.

Most of the parts from a ver2 will work in a ver3. Gears, piston, cylinder(not the head) are all interchangable.
