I just picked up a 239 prefix 10-22 that is in a Ruger factory finger groove stock. I am assuming that it is not correct and am thinking that I would like to sell the stock to someone that can use it on a correct SN# range 10/22. What would be a general value range on just the stock? Good condition with no cracks very minor handling marks. I googled and found little on just stocks. Once I list it I will put a link in the auction section of this site. Thanks in advance everyone!
