Don't take it too hard! The Afghans have been copying and faking guns for so long, that one day someone is going to set up a museum of "Original Khyber-Pass Weapons". I am impressed by what they can do with hand tools and, presumably, a lot of time.
And high-tech is creeping in as well. When I bought my M-H there was another in the shop that had very good markings on the receiver. In fact, excellent markings. Much crisper than the rest of the rifle. In other words, too good to be true. I had to sit down and study the receiver through a watchmaker's eyeglass before it dawned on me - the markings had been photo-etched, like a printed circuit board !
