If I swap the Romy wood furniture on a WASR 10 for Bulgy wood furniture I'm ok since both wood of foreign origin, right? Or is my understanding of 922r completely off? I was also thinking of swapping the crappy poly furniture on the Century AK 74 for some Bulgarian wood furniture. Is that legit? I remember reading that these rifles have enough US made parts already, so this act would not constitute a 922r conflict. Thanks.
