if he is a good friend, I say about 400-450, if he is a so so friend, I say about 300-350
the scope is as old as rifle its rather uselss to me
as would be the mounts
I have bought and sold a few hundred 700's(had a gun shop) and have bough a few dozen on my own, and have paid from 100 bucks to 350 for used one's
I mostly wanted them for actions, so I buy low.
BUT have seen many for sale with decent optic's on them for the 400-500 dollar range,
thus I said, less optic on this one, I would go lower, unless he was a GOOD friend and needed money and was trying to be nicer than what it is, or if I had some personal value to gain by keeping the gun, he used as a way to remember them, if you follow!
how is the bore , looking at the bolt face too will give a clue to how many rounds have been thru the gun too
MOST folks never wear out a barrel, but some sure do!, so that goes into price, as would wear and tear on stock and blue ing
