Hi, my father bought a used in very good condition Remington Model 700 today and is having some trouble with what model it is (ADL, BDL, etc.) and the approximate value. It is a model 700 black synthetic stock, SS barrel, the bolt has swirls on it and the receiver is completely covered with engraving from the factory. It is a 7mm magnum and is ported at the end of the barrel. It has no sights but is drilled and tapped for a scope. The serial number is T62381xx. Any info would be greatly appreciated. Thanks.
