Nevada is an open carry state, meaning anyone can carry a firearm openly.  If you conceal a firearm, even just by a jacket, you must obtain a concealed carry permit.  But, firearms no longer need to be registered in nevada, thanks to nra-backed republicans.  You can also thank donald trump and congressional republicans for the mentally ill being able to own firearms, as they overturned an obama-era rule aimed at blocking gun sales to mentally ill people.  Sad!
