Don't FFLs have to log all new guns into their bound books within a certain amount of time after they arrive at the FFL location? I know when I buy a gun online and it's delivered through my LGS they open the box and take the SSN off the gun itself, NOT the label on the box. I would assume they do the same thing when their own inventory arrives - in part because any ATF audit is going to check the number in the bound book against the one on the gun and not the one on the box, and discrepancies can bring very bad consequences.

If this is the practice, any "sealed box" that comes from the factory is going to be opened by the dealer long before you come in to buy the gun, and a seal won't provide any additional "protection" to the consumer.
