Contact your local law enforcement agency.
If the owner reported it stolen and could provide the serial number, most likely the gun was entered into the NCIC (National Crime Information Center) database. Any law enforcement officer should be able to query the database to see if the gun is entered. If the owner could not provide the serial number, or it was filed off, chances are it will be much harder to trace.

Please note- US law makes it a serious crime to possessany firearm which had had a serial number removed or defaced.
You will have to contact the police to see if it has been reported stolen.
Have the police run the serial number.
If you're found to be in possession of a stolen firearm, expect to be taken into custody. If their investigation determines that you were knowingly in possession of a stolen firearm, then you'll be charged.
With the AR-15 style rifles, the lower IS the receiver, which, by law, IS the firearm. The upper is "parts". Typically the lower is also the most expensive component. If you are concerned that you may have a stolen firearm, contact local law enforcement. Most will check a firearm to see if it is listed on the NCIC system as a stolen weapon, and if so, to contact the owner. If it IS stolen, it is not yours. If you had a gun stolen, YOU would like to have it returned- right?
Report it.
Was thinking of buying a used firearm to defend my home from invasion. But how do I know if its stolen? Call your local police department and have them check it in NCIC. You may have to bring it in so they can confiscate it if it is stolen.
Sorry- there IS no website where you can positively determine that a firearm is not stolen. Law enforcement uses the NCIC system, but that is NOT available to private persons. Local law enforcement MAY be willing to run the serial number of the gun through NCIC, but will need to have possession of the gun while doing it. In case it IS stolen, they have it.
You will have to check with the police.
Yes
Run for what? If you are seeking to determine if a firearm is stolen, there is no website open to the public that contains that information. Check with local law enforcement, and see if they can check for you. If you are seeking age, then it depends on the make- some have data available at their company website, some do not.
When a stolen firearm is entered into the National Crime Information Center (NCIC) it remains on that records until it is recovered, and removed from the database.Added: The above response is correct BUT - it does not answer the original question. A stolen firearm will be entered into NCIC IF the complainant is able to supply the firearm's serial number.
yes it is
