Many years ago I was arrested as a juvenile for possession of a BB gun . It was a handgun BB , a toy in most states but not in NJ . I had police come to my house today and seize my legally purchased firearms and firearms id card due to the state police claiming I was unfit to own a firearm . I served in the Army honorably as an infantryman and handled many weapons in training and in Afghanistan . After my juvenile arrest I have not been in any trouble with the law , no felonies , never a DUI , etc . After doing fingerprints and receiving a criminal background record from the state , I find out that the BB gun was in fact labeled " possession of a machine gun " . A complete lie . What are my options ? Do I have any hope of receiving my firearms back ? Last but not least am I now a criminal / felon ?
