Federal firearm offenses are very serious. An individual convicted of federal firearms offenses can face prison time, long probationary periods and much more. A person prohibited to possess a firearm can face either federal or state charges. Under federal statute a felon in possession of a firearm can face up to 10 years in prison. If an offender has three or more prior convictions they can face a minimum of 15 years in prison, without the opportunity for parole.
