G&G RK103 compatibility question

[Loosecannon16]

Hi,

I have recently purchased this AEG model, and after some skirmishes, i made some gearbox tuning, installed dean connectors, filed down the cutoff lever and tightened trigger switch, to fix v3 gearbox curse.
Now I am looking for a stock and a flash hider that is not disguised as a carrot. (and the stock tangs are pretty feeble)

I was looking for a ak74 stock and flash hider, I've seen LCT parts an interesting choice. so my question comes down to: which RK103 parts are compatible with LCT, what would i need to change?

Getting rid of the AEG to purchase another is not an option. Local market doesn't have any alternatives and importing a whole AEG is too much bureaucracy to digest.

(ps: i live outside of Canada. not for long however)
