WE M4 CQBR Rail`and stock help

[HeadlessRocket]

I recently acquired the WE M4 CQBR and i want to put as many real steel parts on it.

The first thing is i want to make it look like an integrally suppressed H&K 416 or a M4 raptor but have no idea where to start and then i want to put a real steel H&K 416 stock on and any other real steel parts but i have no idea what parts are compatible.

I want to be able to do this without modification and as cheap as possible.

Cheers.
