I went shooting with a buddy today, as he had been complained about some problems with his new AK. When he began shooting it, 1 or 2 rounds would fire, then the bolt would not completely return to battery. This happened consistently, and I don't remember him getting off more than 3 rounds without a malfunction. I have never owned a rifle, so forgive me if I am not getting the terminology right, but I was able to see that the extractor was not allowing the bolt to fully return to battery. The extractor would land on the back of the cartridge, but would not make it past the lip of the brass. Just by a visual of the end of the bolt, it seems like the extractor is set too far toward the center. The extractor is chamferred with a bevel to help it move over the cartridge lip, but I can tell by the wear on the edges of the extractor that the lip of the cartridge is often hitting the flat face of the extractor rather than contacting the bevel. I hope that explaination makes. sense Whats a good fix for the problem? Should the extractor be replaced, or can it be 'tuned' as with a 1911? Thanks for the help!
