I don't understand this question as gun ownership is a guaranteed right for citizens in the United States of America, and by the law as stated in the Constitution of said United States, they (the citizens) implicitly and explicitly have the right of gun ownership.
The grey area of "'who has the right of gun ownership, and how many, and what they look like and..." is a matter of deliberate government misinterpretation designed to limit the ability of the American people to own guns, and for the government to misstate what said ownership is for, as both reasons are plainly stated in the Constitution and the Bill of Rights.
