Can you use VZ58 parts in a CZ858?

[Travel240z]

I was just looking to get a spare parts kit for my CZ858 but Wolverine is sold out. I noticed Marstar has VZ58 parts. Are the interchangeable? I am specifically looking at springs and the ejector as I would expect these to be the most likely to bite the big one along the way.

Thanks for your input!

They are one and the same rifle

Are the CZ858 internals (bolt/piston/etc) interchangeable with the CSA VZ58's?

They're the same gun right down to the exact spec. They're both Vz 58's. The .223 Vz 58 is a different story but most of the gun is still the same as the original Samopal Vz 58.

I believe the only real difference is the barrel length and chroming

The VZ does have a heavier receiver than the CZ. I'd suspect that the receiver walls are thicker. I remember reading something about thicker walls necessary/desirable for those side-mount optic rails. Maybe they're thicker where it doesn't matter for parts compatibility, though. For the parts the OP is looking for, I don't think there is any concern.

Well, the trigger assembly from the wolverine parts kit needed to be grinded to fit into my czh2003, and a little bit had to be taken off the bolt carrier as well.
I also had to add a spring to keep the sear from wandering.

Ejector kind of looks like they're staked in place, or is it screwed?

Firing pins are the most common failure. The tip often breaks off.
