I got carried away with the file and took too much off the ejector on an AK 74. GT 1.6mm receiver. The casing extracts fine but either stays in the receiver or drops right at my feet. My bad, Question is, I've heard that you can build up an ejector with a welder and then reform it. I'm not a welder so my questions are, has anybody done this? I've heard it works but only for 400 or 500 roundds and then starts mushrooming. Then I also heard that it works fine and is a permanent repair. Any knowledable advice or experience would be greatly appreciated.
