I know US parts count on a SBR is a grey area as it depends on who you ask but when converting that little AK in your OP to a SBR I'd likely go ahead and add the parts. Part #1 - Pistol grip looks like a US one and they're cheap if it isn't. Plus there are nicer options out there. Parts 2, 3, and 4 - get a US fire control group, if it doesn't have one already, which will probably be nicer anyway. Parts 5 and 6 - any US brake or flash hider you want. Heck you're almost there anyway and there are a lot of cool options. Well then you need a stock anyway, you could get a US side folder which most say is more comfortable than the under folders or wire folders. OR you could get a US forearm, which again there are a lot of options. That receiver looks like it might be a US one from DC or Nodak, if so that counts as a part.
I mean I'd spend a little money on it because after it's registered you're probably never going to sell it, as a whole gun anyway.
