Ask your local police to run it.
what gun are we talking about here
Contact your local police.
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.
You cannot. The NCIC database that lists stolen firearms is only available to law enforcement.
Your best bet is to call your local law enforcement and have them run the cereal number A FFL (gun shop etc) or a PRIVATE citizen can call the ATF to run a serial number to see if its a reported stolen firearm. See related links for a page on the ATF that covers all this.
If "legal" means those reported stolen, then only law enforcement agencies have access. If your referring to characteristics of a gun, then the BATFE website may be of help.
my knowledge on the sugject is that if a person had no prior knowledge that it was stolen then if the police find the gun and see it is stolen then theyll return it to its rightful owner, this goes for any property that they believe is stolen but that the police do not believe is the owner. so most likely a person would not get any punishment, but that might be effected by local or state laws or it could be effected by the specific situation.
For date made, try Proofhouse.com or maker's website. To see if stolen, contact your local police.
You can't- unless you are a law enforcement officer. However, if you are concerned that a gun you are considering buying may be stolen, see if your local law enforcement will run the serial number for you.
Your question is somewhat vague. WHAT do you want to look up? To see if a gun is stolen? You cannot do that- the database (NCIC) is restricted to law enforcement. However, check with your local police to see if they will check. Want to see when a gun was made? No one answer. For some makes, there are public databases and reference books. Some makers will have that available on their website (Ruger, Browning). For some, there is no information. If you will post make, model and serial number here, or in a private message to me, will try to help if you are seeking date of manufacture.
The AR is an acronym for Air Restrictor in a Nerf gun. When you look down the barrel of a Nerf gun you see a little peg, this on of the Air restrictors. It varies with each gun.
