In trying to make the super shoot more accurately, one of the issues heard about on forums and from individuals is the gritty feel of the trigger for the ak type weapon, when i got my super vepr, both of them in fact had very gritty triggers. The triggers are 2 stage yes, but they were gritty and when you pulled slowly, the feel was just no good.
Sticking to the KISS idea, I don't want to spend any money and don't want to remove the trigger if not necessary. Here is what I did to make a really smooth trigger for myself.
I am a mechanic by trade and have used something called valve lapping compound, the compound is a grease type with grit suspended in it. There is usually coarse grit for sanding conditions and fine grit for lighter work. What I did was put some lapping compound on the surfaces that make contact on the trigger.
This is the trigger as it was before

I used a small flat screwdriver dipped in the compound to put it where it is needed.

Use the screwdriver to put the compound under the hook on the trigger

Next push the hammer down in the cocked position, and move the trigger forwards and backwards to rub the mating surfaces together, you can put the bolt and recoil spring back in as well and cycle the weapon and dry fire it to get the FCG parts to fully rub together with the compound in its natural firing sequence. Dont forget to hold the trigger and allow the disconnector hook be lapped to the hammer.
