Lol I've actually had people bring a gun to me have me fix it and then try to sell it to me as if it hadn't been worked on before. They tend to get angry when you offer them half of what they want.
I did explain to him he would be better off just buying an all original as it would be relatively close to the cost of the build. I also told him I would just buy the barrel/receiver from him for $200.
I don't need No stinking signature.
