| My Yugo M70 has been nothing but trouble. It has always jammed since I bought it. Stove pipe jams are common so I purchased a new bolt because of the ejector possibly being warn out (Century Yugo). Here is the problem I have now, maybe I am doing something wrong: To check cycling, I place an empty shell in the chamber and let the carrier slam shut. I then attempt to pull back the action as fast as possible to mimick firing and to see how the shells are ejecting. At times the shell locks in the chamber and I cannot get the action open. Both the original bolt and new bolt do this when an empty shell is in the chamber; not always though as sometimes the empty shells eject. When it locks up, I can open the action about 3/4 of an inch, but then it locks completely. I do not understand this and wish I had not purchased an unreliable AK. I miss my Romys as they never jammed. |
Sounds like either a short ejector (the thing below the lower rail on the right hand side) or the fit of the carrier and the upper rails (it should be obvious if it really wobbles side to side). From the information you have given, that's the only two things that come immediately to mind. More details may help. And a visit to a local build group may prove even better. AKs are reliable if built correctly. Otherwise the only reliable feature is their unreliability.

| You might try replacing the gas valve. They are frequently corroded and cause a gas leak which can cause short stroking. I would go back to your original bolt, though. Your headspace might be off with the new bolt you bought. Also, your rifle is probably jamming with the empties because they are expanded after firing. You would have to pull a bullet from a live round and play with ejecting that to it doesn't stick |
