Sounds like the hammer isn't resetting properly...thus no click when you pull the trigger...the hammer is probably following the bolt forwards when it picks up the next round. Without knowing more about the conversion it would be difficult to say what is causing it or how to fix. My brother-in-law picked up a Saiga that also had been converted...the person who did the work used AK guts not saiga so all the tolerances were completely off. Had to replace all the guts with proper parts.
It *might* have to do with your gas system...it may not be getting enough gas to get the bolt all the way back. I would start with checking it out. Might need cleaning...might be a gas setting if it is adjustable. If that doesn't do it then start looking at the guts and see if the tollerences look right.
