Unless he can get it a lot cheaper (if the scope and mount are real, if the price is right, then grab it) but for $2k...no way. something really off about that front end, its not duffle cut, the end of barrel seems to protrude an appropriate amount, but the gap between bands is way too short as you point out. Since there is no pic of the entire rifle, its hard to say exactly what's going on...
PS The more I look, the more I think the scope may be one of the re-pops they made...there is probably a thread somewhere here on the markings on the re-pops that would give the best idea...
