Found an old Benchrest rig for sale locally with a 15 x 2"Unertl Scope. Gun is a sleeved Remington xp100/600/660 action in a Shilen sleeve. Has a stainless barrel and is in .222.5 caliber. Stock is an early laminate made of three pieces of wood as opposed to the modern "plywood" thin layers of today. I just want the scope, what would the rifle sell for, roughly?
