(CSA Vz 58) I'm Having Issues Finding Information On How To

[ShotgunNut]

...improve the trigger pull on my CSA Vz. Can anyone point me in the right direction? I'm sure there is info on the sight here somewhere from long ago but I haven't found it. Youtube wasn't much help. I'd just like to get some the extra spongy play out of it if it's not too hard to do.

I'm also trying to find out the thread sizes for the side rail holes on the side of the reciever. Thanks.

You will not likely find info on a VZ58 trigger job.

I took mine from 6 pounds down to 4 pounds safely.

If there is info out there on doing a proper trigger job on these guns I'd love to get pointed in the right direction too,

I'm not sure what this guy does but it looks like a big improvement
