As usual, nobody can give you an accurate price without pics so you should really post them if possible. After all, everybody has different ideas of what a 7.5 out of 10 is. But with the limited info provided, assuming NRA good condition, a fair price for the rifle alone is $575 for a post-64 and no more than $650 for a pre-64 - give or take a few bucks. Higher condition would command a higher price obviously. There may be people willing to pay more or less but those estimates are "fair" prices in my experience with these rifles. I have no idea about the scope.
