Hey Guys;

Got a brand new chrome lined CSA vz58 in 7.62x39 (18.5"). Having run a number of CZ858s for years, I wasn't expecting any trouble. The issue I'm having though is failures to eject (case gets lodged vertically and pinched between the bolt carrier and the sight block) and stovepiping. Occasionally it fails to extract from the chamber and I have to smack the butt on the ground with my hand on the bolt carrier in which case it pops out. Initially I thought part of it might be my striker which seemed tighter than the surplus 858 ones. I swapped it for one and lubed my internals after a good clean and it does not bind at all anymore. Shooting Czech surplus which I've never had an issue with before.

So my question is:

Has anyone else had this issue? How did you solve it?

Has anyone had to emery cloth their chambers on a brand new rifle?

Thanks for any tips!
 
I had that issue with mine right from the very first round fired. It appears that some of the CSA VZ58's have chambers that missed the polishing sequence after the chroming procedure, so some are a bit rough. I had my chamber polished by a Gunsmith friend who had a proper mandrel and all is well, no troubles since. Your issue sounds similar. If I was you, I'd find a smith to give it a polish.

The other thing it may be is a weak extractor, but you said the rifle is new, so I'd go with the chamber polish first. BTW, Emery cloth is way to coarse to use on a chamber.
 
Break in period did cross my mind but I'm leaning more towards chamber polish. Took it apart today, used the cleaning brush to clean the chamber really well. Swapped all the interchangable parts for those from a working and well used cz858 and exact same symptoms. Common factor? Chamber. So the question is, what is the coarsest polishing paper I can use safely in my chamber?
 
Provided you have some sort of slotted mandrel that will fit into an electric drill, about 320 grit to start, Then finish up with 400, then some steel wool. You need to run at a moderate speed and move the mandrel in and out of the chamber to create a cross hatch pattern as you would when honing a cylinder in an auto engine block. The chrome can be quite thin, so go easy. You only want to knock off the high spots in the chamber up to approx. the base of the neck area. For a semi auto chamber, You need it to be smooth, but not a high lustre mirror finish.

If you've never done this before, try to enlist the help of a Gunsmith, or at least someone who has successfully done the job previously.
 
Ihad two stoppage with mine too (223) the first ten rounds then the 80ish remaining round fired without issue. That was with MFS, Barnaul, American eagle and Indepandance 556. I think its just a breaking period, I guess ill find out this saturday again. I did clean the gun before shooting.
 
I bought two CSA vz58s. One of them had poor ejections and jammed with one particular magazine, so I switched the guts and they both fired flawlessly. Just my experience.
 
I've had a number of both 858's and vz58's (x39 only). Both are good. Individual rifles, be it 858 or 58, can have some hiccups. From my experience I"m not sure if I find one better over the other. I give both A+!
 
I don't understand how we still hear about problems with CSA rifles when they charge a pretty penny for them... they should work flawlessly out of the box for the price you pay. But that's just me...
 
I've had my CSA VZ58 for about a year & around 500rds through the pipe. The only issue I've had is a minor annoyance with the castle nut on the AR-style stock coming loose occasionally. Operationally the rifle has been flawless.
