Hi - I read a post from last year regarding a fellow with a AK Legend that would not cock the hammer after firing the first round. Yesterday, 10/01/11, I experienced the EXACT problem he described. I've shot at least 1,000 rounds a yr. out of this gun(since 1991) with no mechanical failure's whatsoever. Same symptoms too, load magazine, pull and release charging handle, 1st round fires, ejects empty, and loads 2nd shot, but does not cock the hammer. PTK said it might be a worn auto sear, any suggestion's? Nothing appears to be broken. Is replacing the sear something I can do myself? I do most of my own stuff, but 've never had to work on this weapon.
