I have no experience with this so I need some help. I have a buyer for the take off barrel from my build. I have had it since new. It's off a Remington 700 ADL .22-250 it's got less then 100 rounds down it and never heated up (coyote gun) It hovers around 1 inch groups at 100 with good factory ammo. Finish is in great shape. What is a fair price? It's for a friend of my fathers and I don't want to rip him off but I don't want to give it away either. Any imput. Thanks in advance.
