Cyma AK anatomy and installing wooden furniture

[Andrus_Arseen]

I've been thinking of buying a Cyma AK and making a wooden handguard, stock and grip for it. Are there any internal components in the aforementioned areas that would get in the way?

The model I've been thinking of buying is the CM.522

Pistol grip would have the AEG's motor inside and the stock is where the battery is typically stored on these models. To be blunt, it wouldn't be the model I would go for. 

 

Something like an AK-74S based replica might be an easier choice. Would just be the handguard then to do.
