There is no easy way for a private citizen to check the legitamacy of a given firearm. The stolen gun database (NCIC) is a Federal computer system open only to law enforcement. MOST states do NOT have a system nor a requirement to register guns. Local law enforcement MAY be willing to run your gun through the NCIC system, but will want to have possession of the gun in case it IS stolen.
Go to your local police with the sn. If it's been reported as stolen they can tell you.
Expect the police to expect YOU to explain how you came to possess a gun that had been stolen- just like any other property.
Contact your local police department and give them the serial number. The Police can check on the stolen gun list maintained by the BATFE. If the gun is stolen, the Police will conficate the piece and begin investigation of how it was acquired.
Contact the police
Go to the seller where you purchased the gun.
Contact your local law enforcement. They can check to see if the serial number has been entered as a stolen item. IF there is a report, the officer will need to retain the gun to return it to the owner. They WILL need to have the gun in hand to do this, not over the phone.
Go to the local police with the serial number.
If you just bought it and ask the police to check it and then it turns out to be stolen, in all likelihood you'd be in no trouble at all; you're just trying to verify the gun is clean. If it does turn out to be stolen, however, the police have to confiscate the gun, so you'd be out whatever you paid for it unless you filed a civil suit against the seller.
Strictly speaking, it's neither, but I know that's not what you meant. Owning or possessing a gun that is actually stolen CAN be a felony, however, it isn't always a crime. If you find out you have a stolen gun, you can, in most cases, turn it in to the local police without being charged with anything.Added: The biggest factor is if you KNOW that it IS stolen, or SUSPECT that it MIGHT be stolen. If you do not eliminate the doubt and confirm its legality you could be charged with Receiving Stolen Property.
Probably not online, but any local police station can run the serial number and tell you. If it did turn up stolen, you wouldn't be in any trouble, but you would lose the gun.

Pawn shops are a legitimate business, and tightly regulated under state and Federal laws. To pawn anything, you will have to provide them with your ID. If a firearm has been reported to the police as stolen, information on that gun will be entered in the NCIC computer system. When you sell that stolen gun to the pawn shop, and they enter it into their inventory, the computer system recognizes it as a stolen firearm. You get visited by the police who arrest you for possession of stolen property.
