Clean the barrel out the best you can until it looks good. Clean the bolt and action. Lash it to a tree, tie a string around the trigger, take cover, and fire it. If it's still there and the barrel looks good, disassemble it, do what you wish to the stock, paint the barrel and action flat black, and keep it for a truck gun. (The aforementioned comes from many previous experiences....)
