I have parted out several K-Guns and P-Guns and have sold the parts on here. I find that is the best way to sell. Example: If you decide to sell the entire gun, you have to find someone who is wanting the entire gun. With a K-80, you could sell the receiver and forend iron and someone would buy who is looking for a back-up. Take the barrels, someone might want to keep their barrels original but really want Wilkinson or Allor work. They will buy the barrels.
I have always made a quicker sale of gun by parting out.
