I had no idea it was both super easy, and could make such an enormous difference!!

Every sks I've owned has had a terrible trigger. And my most recent one is no different. About 3 and a half kilometres of gritty creep, so bad I had no idea when or where it was gonna finally break. So I took to YouTube and found the video posted below. It's an excellent walk through for anyone who wants to do some work to their trigger.

I first discovered I had a pretty serious case of negative sear engagement. So I used fine files and finished with 600 grit wet dry to recontour the sear to a light positive engagement and smoothed it up, along with the engagement area on the hammer itself. Then I removed as much creep as I thought I could get away with by removing some of the face of the sear a little at a time. It now safely passes the bump test but the creep is all but gone and hardly noticeable. I also had to cut the disconnect arm a little to keep it functioning as the positive engagement removal made so it was just barely catching.

Lastly, I installed an over travel screw. I had a couple option with how to proceed. I was either going to use a small grub screw in the rear of the trigger bar just below the trigger spring (this would be unnoticeable on the assembled rifle), or a straight set screw behind the trigger threaded into the guard. For the sake of simplicity I went with option 2.

What... A... Difference!!! It now breaks SUPER clean at about 3 pounds, extremely little creep, and almost zero over travel. It's now one of the best triggers I've EVER felt on an sks. Ever.

I'm one happy shooter!
Cheers

Great WORK! It makes a massive difference indeed; especially for "bump" firing lol. 3lbs is pretty damn light though, Id be careful to only have a round chambered once your ready to actually shoot. I had an SKS trigger down to 2.5lbs once, The Sear would slip out time to time under the recoil of the gun. God help me if I ever dropped it and it pointed my way. Reversed the mod within the same day of test firing it, It sits @ 4lbs now and has done so for years; but I still dont trust it 100%, you never can with an SKS trigger.
 
I tested the trigger pull weight when i got home and it breaks right around 3lb 11-12oz. There is enough positive engagement and "creep" to prevent it from slipping under recoil I'm sure. I won't know for sure, sure until I take it to the range.

You got that right, I had one that would bump fire, if you looked at it the wrong way, very dangerous POS, I tossed it out in pieces after it scared the sh!t out of me one time
 
Tried it out at the range today. Got one mag out no problem. Second mag, I got two shots off, then it bump fired two rounds and jammed on the last round... I immediately put it away... Looks like I'm going to have to add some creep back to this trigger, and maybe give it a bit more over travel...
 
You can try solving that problem by replacing the mag release spring with a much more stiffer one. No guarantees though.... But it worked for mine.

Give it some more over travel. You need it for the disconnector to work properly.
 
I am experiencing the same thing with mine after a bit of tinkering and adding an over travel screw. It's not like the hammer rides the bolt, it wouldn't fire the round then. It feels like unitended bump firing. I think it's a combo of less take up and no over travel.

If it's bump firing unintended, it's almost certainly the sear slipping out from underneath the hammer.

Absolutely could be. I thought I left enough creep and it has quite a positive engagement, but I might take a bit off the face of the trigger bar to give it some more creep.

Almost wishing I had left well enough alone now honestly.
 
Sks trigger unmodified is very safe, with the safety on its pretty much foolproof. Never tested but the pull is not light at all. If your going to use this for target practise have fun. For hunting I'd want something with a bit more heft.
 
my 2.5# trigger pull passes the drop test, and by drop test I mean throwing it as hard as I can on the buttstock.

Don't see how much safer it can be.

Thats why you always test after a trigger job.
 
The round is fine, slow moderately expanding bullets are reliable game takers. sadly the rifles point of impact shifts wildly between types of ammo though, that and the trigger makes marksmanship in the field a bit more difficult.
