Chunk missing off face of CZ 858 bolt.

I had this EXACT same failure today. I got my 858 used so no warranty for me :(

Get in touch with Wolverine. They'll likely have a replacement bolt. $50 I believe. That's if they have some in stock. If not, I don't know if they are still getting parts.

I've only put 200 rounds through mine since getting the bolt replaced. Now with the 858's quickly becoming unobtanium, I'm afraid to break the damn thing again.
 
I bought the very last bolt assembly from Wolverine about 2 weeks ago.
Hopefully they get more. I bought one just for the hell of it for this exact reason.. Parts will be harder to find.

Common problem for high round count bolts. Just remember that these rifles use surplus bolts so the exact round count is unknown.

For me it wasn't high round count. Something was/is out of spec on my rifle. Left side of the bolt is contacting the breach face hard enough to cause a wear mark to show. Over time, it caused it to crack. If you check my post history I posted pics of it. Mine was one of the first of this recent batch to experience this problem.

I covered the new bolt with grease pencil and let the bolt slam home. Looks like it's doing the same thing.

My rifle is still under warranty, but with no new ones coming into country, I highly doubt I'll ever see it repaired or replaced.
