I recently got a Romanian CIA Ak74 on trade that looks new on the outside and the guy I got it from is a good friends brother in law. He told me he traded it to his brother and has 500rds through it. I just took it out and fired 60 rds through it and all but 5 or so I had fte problems. I did some research online and saw most guys having ejector problems but i have had several people look at my ejector and found no problems with it or the spring. Plastic mags have 1/8 in play so I was thinking of that but assume that would cause more of a ftf vs fte...? I have been staring at it for 3hrs or so and saw some minor machining problems and some burs i filed flat. I was just getting ready to put it back together and noticed the bolt appears bent where the steel threads in to the piston part. Wondering if anyone is familiar with these and/or this sounds like a possible culprit. There appears to be some possibly "more than normal" wear on where the steel threads into the piston rod possibly from rubbing on the front receiver. Pics show the gap in the middle and rotated 180° in 2nd pic with big gap on the piston side.
