Changing out your stock is simple and in my experience has been one of the largest improvements you can do. I have a Bell and Carlson Varmint/Tactical stock that is really good and made a real improvement in the rifle and my shooting form.
I'm going to put on one of the new Stocky's Stocks Bobby Hart wood laminate stocks, those will need to be pillar bedded but it is real easy and no big deal to DIY.
Stockade stocks provide a real nice stock and are an excellent value if you can do some minor finishing.
