I ordered one Russky SKS through frontier' and I am thinking about replacing stock with something more modern, like ATI dragunov or folder. Which one of stocks is the best fit and provides better accuracy? What glass works good for SKS. I heard receiver cover scope mounts are not solid enough - is it true? Also I would appreciate recommendations on slings, bipods and whatever you think is important. My first SKS, so I would appreciate any advice.
