I'm sorry to here about your friend .
I've done some quick research and the prices I get range from $650 to $1,100 the $650 would be a little low for a stainless . Need the model and a picture to give a good estimate . Also do you know what the gun was used for . Target , Hunting , Competition ? If it was used as a competition rifle it likely would have a few more bells and whistles . What is the exact scope on the rifle if any ?
