RE "experts": since joining SKS-F I've learned that one (amongst the many) of most value-added aspects of the site - it's a place where a bunch of folks can sort through practically any opinion or view - and not end up going into butt hurt tailspin. Collective EXPERTise.
That was the main intention when we founded this site back in '14. Just to have a nice place where we could consolidate info, gather data, and simply talk w/o getting wound around the axle like you see on so many other sites around the web.
Other sites, especially SKSBoards (AKA the 'other' boards) would have exactly that where one of the good ole' boys would set you straight and tell you how ridiculous your question was, berate you for calling it a 'Norinco', remind you that you didn't introduce yourself, belittle you because either you weren't there when they were imported so your opinion is irrelevant or you don't have 3 East Germans in your collection so your opinion is irrelevant, and finally pooh pooh the gun you just bought because it had a mismatched receiver cover.
We finally had enough and SKS-Files is the result.
