Nice looking rifle, from the pictures provided it look like some type refurb was done. the bolt is parkerized, not the original blued and the trigger guard is a Remington also and is parkerized and not blue (there is the straight step on the trigger guard by the forward mount screw). As for the story that rifle was his issued weapon is doubtful because US personnel turn in their US issued weapons when return back to the states. There been several other thread about this subjects and the opinion is just a story to heighten the intrigue of the rifle. But still look like the rifle is in good shape.
