From what I've seen, your best bet is to avoid American made with the exception of PSA gen 3 and newer like the AK-e. Arsenals are made on parts from, if I remember correctly, Bulgaria. Yugos require some non standard parts but that only matters if you're going to change like the stock., easiest way to spot one of those is they put an extra vent hole in the forearm. I may refinish my Opap stock because I like the looks of the dark red wood instead of the lighter colored on there currently.
