The upper and lower receiver cannot be interchanged with other brands/parts without modification. Even the cyma mp5 full stock needed to be shaved down to fit the g&g mp5.
The scope mount claw might also have different dimensions and the handguard might also need modification if you want to switch the handguard. E.g. mp5sd or the a3 handguard.
Iirc the internals are interchangable except the gearbox might be specific to g&g guns.
I only owned it for about 6 months before parting with it.
