vz58 Trigger Issue

[sanderle]

I have a Czechpoint vz58.  I bought and installed the Bonesteel vz58 FCG two years ago.  It has worked flawlessly until my last range session.

I fired through one magazine without problems.  Set the rifle to safe, reloaded, handed it to my brother.  He set it to fire, but nothing happened.  The trigger was not resetting.  Unload/reload/safe/fire.  We could not get it to fire.

I was going to take it apart tonight, but I cannot get the trigger to release the receiver cover.

How do I get the receiver cover off now?  Ideas on what is going on with the FCG? 

The rifle has less than 900 rounds through it, the Bonesteel FCG even less.

If I could get the receiver cover off, I was thinking of putting the stock FCG back in to see if that would solve the issue.

Any thoughts or suggestions?


Thanks

Is your safety backing out?

Trigger moves disconnector.  Safety allows/prevents disconnector to/from reach/ing sear.  Disconnector interfaces w/ sear to release the striker. 

So lateral movement of any of those three could be causing.

That could be the simple fix.  See if you can push the safety pin sideways in and out of the receiver.  The movement should be small, about 1-2 mm.  Pull the trigger as you work it to see if it will catch.  If that's the problem, then post again as there's a reportedly easy permanent fix.

Some have posted that to remove the cover in such a situation, you can remove the pistol grip, then fish around inside the receiver with a curved tool to release the striker.  If you try that, study some pics of the FCG to get an idea of what to do.

See if this helps. It did when I had a similar issue:

I was able to get the receiver off, and repair the FCG.

The safety selector wasn't loose, but when I pushed on the seer pivot pin while changing the safety selection, I was able to get the trigger to engage.

I removed the seer and trigger/disconnector.  I reinstalled the stock trigger/disconnector, but reinstalled the Bonesteel seer.  Reassembled and test fired before putting the e-clips back on.  No issues.  Reinstalled the e-clips and reassembled, and again no issues. 

On visual inspection, it appears that the thin part of the trigger block on the left side of the disconnector is thinner on the Bonesteel trigger.  I'm guessing that this allowed some movement and caused the disabled trigger.

I will be visiting the range this weekend and will see how reliable the new configuration is.

On a side note, I don't really like the plastic stock trigger.  Has anyone swapped it for the all steel trigger assemble that Czechpoint offers?  I know that it is a Czech part, but I have a couple of US parts to keep things equal for 922r compliance.

Good job on fixing a frustrating problem.  If you want to use a steel trigger, would a shim/spacer/washer bring the Bonesteel part back to working order?

Reminds me of this video:

*I do not have a Dtechnic, CSA, or Bonesteel trigger, but most canadian rifles are CSA, so I'd think the video advice should apply in your case, but no guarantee.

Some Bonesteel/CNC fcg parts were deburred too aggressively. This can definitely cause problems. For example, if the axis pin holes are beveled too deep, there will be too much side to side movement. I've seen it a few times now. When pulling the trigger, the disconnector will slip off the side (from the bottom) of the sear, instead of pulling it down to release the striker.......My personal fcg had this problem. Bonesteel confirmed the issue and replaced it for free. He told me there was a bad batch.

You'll typically have a faster response w/ CNC Warrior.  And since they made them, they'll usually replace the Bonesteel items as well if you contact them.

[sanderle]

I'll have a look at the video, and CNC Warrior.

One the plus side, my current setup (Bonesteel seer, stock trigger/disconnector) worked flawlessly through 150 rounds today.  Most of that was rapid fire.   

[Varickm]

When you call CNC warrior, make sure to request a complete fcg replacement. This is a tolerance stacking issue. After pulling the trigger a few times, the trigger/disconnector and sear can walk in opposite directions.

Another 120 rounds through the gun today, without issue.  I guess I'll leave my current setup in place for a while.
