I have been floating around these forums for a while and it seems many people advocate building your own FAL or AK-47. I think that is a pretty neat idea, looking around i see that most of the parts can be had without any difficulty whatsoever. The only thing you need after buying a parts kit is a reciever, i have two questions, it is very difficult to build your own rifle from a kit? also, how hard is it to come by a reciever for your rifle, can i buy one at a gun-shop or are they only avaliable to FFL's?
