I have a sav 11 with a flimsy stock. I was shooting off a bipod one day and it was all over the place. Long story made short, with the bipod you could tweak the stock enough that it would touch the barrel and effect accuracy. Once I figured that out and shot off bags it shoots pretty good groups.
I think your stock is parr for the course.
I don't think there is a fix for that stock.
