I recentaly got a WASR 10 63 AK{my first AK}..I was told it had an issue with the bolt holding back after you fired..ie: you have to manually move the bolt forward after each shot. I was told it cycled ok once the rifle heated up I took it apart this morning for the first time and noticed what looks like a broken spring...can anyone tell me what this is and if it is indeed a broken spring,whats the correct part name and where can I get a new one and could this be the cause of the issue? I havent fired the rifle yet so I'm not 100% sure it has any issue at all..just going by what the original owner told me. here is a pic of the part in question. Thanks.
