First time I ever shot my SKS off a bench for accuracy. It did better than I thought- all 10 rounds were "minute of bad guy" at 100 yards, and I think the main limitation was the horrible standard battle sights and creepy, heavy trigger pull. With a good trigger and optics I think it could shoot 2 - 3 MOA easy.
you can pick up an pack of wolff springs for around $9 plus shipping, you or an gunsmith willing to do the trigger work.

good shooting with opens sites anyway with the old battle rifle.
nice group with the old cva too
