Hey guys,
I was looking for a trigger upgrade for the csa vz58 because the factory one has a huge useless travel before the disconnector get in contact with the sear pin. that is an issue for me as it reduce shooting speed and accuracy. I searched everywhere and it doesnt seems to exist a specific trigger upgrade for this gun. I found a guy on youtube selling is service for doing the trigger job for 205$ usd. No thanks for me.

So i disassambled the trigger assembly and after few hour of testing i found a reliable solution to produce an awesome result.

Before the mod the trigger had;
-a useless travel of .250" and a total travel (until fire) of .420"

After the mod the trigger has now;
-a useless travel of only .095" and a total travel (until fire) of .200"

Cant wait for the results at the range.

First I took a small piece of a steel sling that comes with my russian bullet for my shim. It was about the size i needed to get rid of that useless traveling (.035")

Then i cut it to the wanted size and made it 90deg to fit the shape of the trigger.

Paint it, glue it on the trigger with epoxy. thats it

Then in order to reduce really slightly the travel before the trigger release the striker you need to file and polish the sear. dont do it too much because that will make your gun unsafe!

Sure, the file+polish step depend on how you reduce the sear material. In my case it has reduced the "second part" trigger travel by .065"

With both travel reducing has resulted drastically increasing rate of fire! Getting better accuracy is possible because you reduce an unwanted, too long trigger pull.

Yes its a plastic trigger. Thats what it comes from CSA factory. Its good enough..

I finally got around to checking the trigger on my CSA VZ58, and it has a metal trigger! Which is what i originally thought it was :) its odd that some are plastic.
 
The one pictured in the OP sure looks plastic judging by what looks to be a seam running down the center of it....if it is maybe it’s a 223 thing!

My 2 newest vz's have plastic triggers both 7.62. I'd rather steel but they seem solid.
 
Hello every one, my csa vz 7.62 is new of this year. And trigger is hard plastic. I would prefer steel if i had choice but its tough enough anyway. Thats just a question of feeling. If you shoot with glove, you wont feel any difference XD

Next step, muzzle brake ;)
