RE: To do or not to do?
Well whether or not you bite on the price is really a matter of how bad you want the rifle. I have paid more for a rifle then what others felt it was worth, only because I really wanted the thing. Sometimes money is not the question.
If the stock is messed up, then you are going to have to consider the fact that if you can not fix it and make it workable, you will have to replace it. Replacing stocks can get expensive. While the barrel, caliber, and lock would be appealing, I just do not know how appealing it would be.
Only you can judge if it is work the extra $25.00 to you. It sounds like the person that owns it has a set price in their mind and might not dicker it.
