I have a M77/50 that I put the 209 conversion kit on shortly after I got it. Never had an issue. Was out hunting the other day and fired a couple shots decided to come home and clean it. I had two small metal pieces fall out after I removed the bolt. I'll try to attach pics. Anyway, I broke it all down as usual and cleaned it all up. Put it back together and when I put the bolt down the firing bolt slammed forward. Tried it a few more times with the same result. I took it all apart again, pulled the trigger assembly apart and I can't figure out where the pieces of may have came from. Trigger feels a little sloppy. I've looked at the schematics over and over and can't see any parts that match the pieces that came out. Everything seems to be in place. Help please!!??
