This report is all over the shooting forums. Did the importer take care of the issue in the end?
I have only one import complete "civillian" Zastava, an M77 that came in a sissy thumbhole stock. I put milsurp furniture on it, squared the angle cut receiver and put a tabuk flash-hider on it. Now it looks like an actual DMR issued rifle. It always ran great and does best on GGG Lithuianian NATO. Otherwise I have either complete milsurp yugos (Mausers, SKS's) and milsurp kit builds: M70B, M70AB2 and M76 kit guns that all look and run like tops. Had a lot of problems getting the M76 finally built and rebuilt correctly. Mario @ Pice of History finally got it going.
The M70AB2 was an early Century build and it's action (surprisingly) cycles the best like butter.
