I think $150 to $250 is a fantasy. If your factory stock is plastic, you would be lucky to get $35 for it. As for the barrel, I'm not that familiar with the value of Savage barrels but I have sold quite a few Rem700 factory barrels and you feel good when you can get $30 (shipped) for them.
I'm not gonna shoot here. I'm gonna shoot waaaaaaaay over there!
