Just want to share this information with you all Nevada residents. If you are going to register your firearms, please go to the Metro Station at 1851 Stella Lake St, Las Vegas NV 89106. It's on Lake Mead & M Luther King.
At first i went to the Metro HQ by M Luther King. They told me to go to the Stella Lake station as the HQ not accepting registrations.
I arrived around 11am and i was the only one. So it only took me around 15 minutes.
