No felon can buy, posess, or live in a house or dwelling where firearms are present. Furthermore if a non-felon buys a firearm for a felon as a gift or to cover for them because they cannot pass the 4473 background check they are aiding a felon and punishable by the same prison sentence. The standard sentence for felony possesion of a firearm is 10 years in a federal prison. But that is rarely handed out. However it would greatly benefit the U.S. if it did hand out this punishment. However, to clarify part of the answer, the spouse of a felon can own a gun, as long as the spouse can otherwise legally own the gun.
