I'm relatively new to servicing and accessorizing firearms but i bought an sks about 2 years ago and went to town on it. Here's what I did maybe it can give you some ideas!

I started with the stock I put a tapco 6 position adjustable stock - very easy instructions are included with most stocks and there of plenty of instructional videos on youtube. Next was the trigger I like many others experienced a bump fire with this rifle and did lots of research on the subject I found one very helpful video that showed me how to change my negative hammer to sear engagement to a positive one. which drastically reduces the chance of a bump fire, in the video it also taught me how to take some not all of the creep out and smooth the edges of the sear a bit for a crisper trigger pull. ( I am in no way an expert on the subject and I was well aware of the potential dangers of messing around with the trigger group. Do so at your own risk or take it to a professional. ) after that I purchased a rear aperture sight that mounted in the place of the take down pin on the receiver cover - also came with instructions, however i soon realized that every so often when taking it apart for cleaning it would shift the zero of the sight and I'd have to realign it. After that I re-blued some of the parts in the action after noticing some corrosion due to firing corrosive surplus ammo. And lastly I bought a rubber recoil buffer. I know these are very controversial and some people are skeptical and while I did not notice any difference in felt recoil I loved the way it tightened up the action I stopped getting jams due the springs increased tension I believe and in my mind it took way some of the metal on metal contact from the action spring it was 10$ CAD and for the piece of mind I found it to be worth every penny. There was one more mod I wished I could've done before I sold it and that was the infamous free floating firing pin that was known for getting stuck and letting the rifle fire full auto uncontrollably I believe you can get kits online to add a spring to the firing pin to help with the problem from what I've read some years of different variations came equipped with this spring returned firing pin. This problem can also be avoided by properly cleaning and lubricating the firearm but if the owner wishes its definitely worth looking into/

I hope that's what you were looking for, and good luck from a northerly neighbor!
