I've got a MAK 90 and I'd like to get rid of the hideous wooden thumbhole stock. It's really thick and unpleasant to use. I was considering a more traditional stock and pistol grip but I understand you have to keep track of parts to make it legal. Sigh. So if I were to buy a stock/pistol grip/handguard kit that's made in the USA, then I think I still need to replace some other parts. I doubt my magazines are US-made. What else do people usually replace? I think it's all very silly but of course want to stay legal.
