I have an FA mp5k clone which used to run well and now stove pipes a lot. I have tried different ammo and bullet weights to no avail. I have tried replacing the extractor spring which did not help either. I have tried replacing the entire bolt head and the ejector as well, you guessed it, still having problems. It stovepipes 2-3 times in each magazine. yes im using hk mags. any ideas?

What does the manufacturer say ... ?

I have the same problem. Might it be the extractor?

Did you recheck the bolt gap after you replaced the bolt? If that's good try replacing the extractor. If it still doesn't work, send it to a professional for surgery.
