I just did the trigger job on my new to me Chinese SKS. I got it with a great deal of negative sear engagement, a gritty pull, and a lot of creep. I understand that this is normal for these guns. After my work, I now have a very positive engagement, the discononnector is working correctly, and the safety is functional (sort of). So my work seems to have been successful. I am happy my first go at this went as well as it did. The trigger does seem quite heavy, but it is much smoother and breaks more crisply. I am going to order the Wolf Springs. I have 3 Newbie questions pertaining to this work.
While the safety is working properly, I am concerned that the clearance between the trigger bar and the sear may not be enough. When I look through the hole and observe the gap, it is very very small to the point that it is almost imperceptible. The sear doesn't move when the safety is on and the trigger is pulled very hard, but it looks like there is absolutely no clearance between the two at all. As long as the sear doesn't move should I leave it alone or should I do a little more work to open that up a little. I think I read somewhere that the gap should be about .05 or so. So if I want to adjust this to give a little bit more of a safety margin, what do I adjust the sear or the trigger bar?
Secondly, the video I watched said to blue the components when finished. It seems strange to me that you would blue the parts you just spent so much time polishing up. And the bluing will probably get warn right back off anyway. I am thinking about skipping this step and just leaving it shiny metal. I will then put a good coat of something like Frog Lube or Weapons Shield on it. What do you advise?
Finally, the Wolf springs come in three flavors - 27 lb, 31 lb, and 34 lb. I assume the 27 lb spring will provide the lightest trigger pull and will help the heavy trigger. I also hope that when I get the trigger group all lubed up it will make the trigger a little lighter as well. The recommendation is to use the 27 lb spring if you only intend to use ammo with boxer primers. Since I don't know if I will ever use surplus ammo (I assume I will because I am cheap), then I should go with the 31 lb spring or even the original 34 lb spring. Your experience with this please.
Regards,
You do not want to make any adjustments to anything other then the sear and smooth the rails. You want zero contact to the sear when the trigger is pulled hard against the safety. Your pull is hard because you likely have too much positive slope. Dont get the lightest springs or you may have light ftf strikes.
