Gun rights group sues Gov. Sisolak over “ghost gun” ban June 11, 2021 Gov. Steve Sisolak signs AB 286 which bans 'ghost guns,' on June 7, 2021. Image: Nevada Governor's Office Share Guns made at home using unfinished receivers are known as “ghost guns.” They earned this nickname because they lack serial numbers and are thus untraceable when they’re recovered after being used in a crime. Ghost guns are assembled at home and often sold in kits that include all of the necessary parts to turn the unfinished frame or receiver—the piece of the firearm that contains the operating parts of the firing mechanism—into a fully functioning gun.
