IMO, that would be full price.
The scope sells for around $800 or so on Ebay.
Blue Book shows .280 as the highest priced Rem 725, listed for $800 in prime condition. Blue Book is historically behind the market, OK in a static market, but a moving market will find Blue Book values lagging. So, is the 725 market static or beginning to move? I don't know. Based on price, I'd say .280 is in most demand, probably based on numbers produced.
So, it depends on how bad the OP wants that gun.
$1,600 would be my offer.
