Gentlemen, I need help and opinions. Here's my predicament;

Went to the range to zero my brand new, previously unfired CSA VZ 58 11.5" Folder. It is not stock, I have had it re-finished in Arma-Coat, added a Dlask AK brake, and a NEA Ambidextrous Charged Bolt Carrier. The magazines used were the ones that came with the rifle.

Ammo used was Norinco 7.62x39MM M43 Ball Cartridges, 123 grain Steel Core FMJ, Steel Cased, Non-Corrosive.

I loaded up both magazines, with a giant smile on my face, and that little twang of excitement we've all had when we're about to fire a new firearm for the first time. Inserted the mag, chambered a round, squeezed the trigger and fired. It went bang, but it was all down hill from there. Stove pipes, double feeds, failures to eject, hard jams, and I mean HARD. I cleared round after round of crap and frustration. I only got through 30-ish rounds and was becoming increasingly furious. I had an 870 with me and briefly fantasized about firing slugs and doube-aught buck at my new purchase. However, I settled down and considered that it might possibly be the ammo.

Stock was extended and locked open, bolt was traveling smoothly and seemingly unobstructed; no grinding or binding anywhere. At least none that I could see or feel.

I stripped it, went over everything and couldn't see anything mechanically wrong with teh firearm itself. I honestly don't know if it's the rifle or the Commie Ammo. Anyhow, I will take pictures of the rifle once a few of you VZ Vets chime in and tell me specifically, what you want me to take pictures of.

I need to figure this out, I'm kind of frustrated. Suggestions, comments, ideas and opinions welcome. I need to know what you guys think.

Untill then, here are pictures of some f'd up rounds that either jammed up, didn't extract properly or double fed, hell one bullet was even rammed further down the throat of the casing. Fun...

Thanks in advance for the help.

Is your bolt carrier well lubricated?

Sharp edges on the inside of the feed lips can cause feeding issues as they dig into the cases (that's the line marks on the cases in your pics) and slow the carrier down.
 
Try putting the original carrier back in and test with the ammo you have. After that, if it doesn't work, remove the Dlask break. Basically return it to original condition and start adding one thing at a time to see if there is a function change. Hope that helps. Hope it works for you. Nothing more frustrating than a blaster that doesn't bring a smile to your face.
 
VZ Problem

Check the feed ramp for lips or Burrs.
Try Czech ammo.
Try holding the mag firmly back and firing.
Try using high temp lithium grease to lube the rails of the carrier.
Strip your mags and make sure they function and that the rounds slide out properly.
Those coatings do add some thickness to the receiver however these rifles should have no problem.

QUESTION:
When you dry cycle the rounds in all of your mags, do they feed and eject properly?
If the answer is YES then that narrows the problem down.
Good luck.

My buddys CSA had a issue just like this ,, he's not very good mechanically so he gave it to me to take a look at .. Well i found the problem , the shell ejector tab thats staked into the floor of the receiver(not extractor claw in bolt) the bottom edge of the base of the tab was protruding into the magwell a bit causing contact with the magazine putting downward pressure on the mag, this was causing the mag not to seat fully up enough,, well i filed the base of that tab down a bit and it fixed the feeding problem..
 
Thanks for the quick responses. I'll be trouble shooting (literally) Monday evening at Windsor Action Pistol. I'll start with the Ammo switch and go from there. So far, I've compiled a list of possibilities you guys have suggested.

With all the help, I'm sure I'll get to the bottom of this.
 
Every problem has some kind of solution. The Czech ammo will be waiting for you Monday morning where we talked about it. Best of luck bro! I'm feeling what BCViking is saying.... a mag that's not fully seated would cause all that drama, and it wouldn't take much. YOu'll have an ultra reliable machine soon.

Here are some snap shots of the internals and the receiver.

Anything stand out to anyone?

It looks like some one altered your ejection tab on your receiver.
This is what it is supposed to look like:

If different magazines didn't work try to JB bore bight the chamber and also polish it up with some flitz.
If that still doesn't work and you have also ensured that you are seating the magazines properly I would call the place who sold you the rifle and ask for an exchange. If they won't do that then the only other choice you would then have is to call Dlask and ask them to try and fix it for you.

What do you see that gives that impression?

His ejector looks identical to the one in my CSA.

Look at the verry first picture that he posted then look at the standard reciever pic that I posted. The ejector post is preaty much straight on the normal 858's but on his it apears to be on an angle.

Like I said, it's the same as my CSA.

Cool did you notice any change in the ejection path?
As for md519 please return it to the store you got it from. Cause I see three things that don't look right to me.
  1. Locking Cam has a dent on it on only 1 side.

  2. Dent or mis-shaped left side of mag port

  3. Also this is the point that I think is causing you the greif. The feed ramp. Although this rifle should be covered under warrenty so I wouldn't even deal with it.

Compared to my friends CSA 11.5" VZ58 - same exact rifle, yet major differences in components. His is stock and has not been modified. I've had mine refinished.

Things to note;

When I pull back on my charging handle all the way to the rear, and then walk the bolt forward, the bolt will stay half cocked, literally sitting half way across the mag well. If I pull the trigger it will send the bolt and charging handle home. I am not locking the bolt in that position, it just stays there if walked there. Like riding the bolt forward, walking it to that position.

I was only able to compare the bolt components with my friend's components. However, he had his CSA and a CZ on hand, neither of his rifles stayed "half-cocked". The bolt would not sit half way across the mag well like mine.

Very strange. One thing I do know is I certainly will not be firing this thing anytime soon.

Check the pictures out.

md519,
Yeah, the bolt and locking block are slightly different, but I don't see those differences being operationally significant.

Having the bolt carrier hang up when you ease it forward is no big deal. Especially with a new rifle as they do require some break-in. Mine initially had a few feed issues but that went away after the first 100 rounds, or so.

You never commented on how your rifle was lubed. Grease the receiver rails/bolt/bolt carrier well and always let then bolt carrier fly shut. Never ease it down.

Where are you located?
 
Update

Sent her out to Wolverine for warranty work. Mr.Wolfgang polished up the throat and she's spinning like a top.

Minor issue. Nothing too serious. Also gave me a new dust cover as my old one was slight bent.

All is good in the 'hood.
