Zastava wouldn't likely be interchangeable with CZ, looks like different designs.
I have both a CZ 550 in .270win and a Zastava M70 in .375 H&H and I was cleaning them both at the same time. When I was done I was trying to put the bolt back into the CZ and was puzzled as to why it wouldn't work. I was thinking, What the hell? It was working just a moment ago." I was trying to examine the bolt and figure it out for about 5 minutes when I stopped and decided to put the Zastava back together and then I'll come back to the CZ and figure it out. Put the bolt in and then.... What the hell!? Same problem! I'm looking at the gun and then the bolt. I then though, Hey I must of never noticed this before but the bolt shroud for the Zastava is exactly the same as the CZ's bolt....... 10 second pause and then.... Oh ####! I'm trying to put the Zastava bolt into the CZ and the CZ bolt into the Zastava. The bolts to both rifles will make it passed the bolt stop like they're made for it but once you make it to the ejector its game over.
I have nothing to contribute to the original post..... Sorry.
