•      "Ghost guns are the fastest-growing gun safety problem facing our country. ATF estimates that more than 70,700 suspected privately made firearms (i.e., ghost guns) were recovered by law enforcement between 2016 and 2022—nearly two-thirds of which were recovered in 2021 and 2022.1 They are becoming a weapon of choice for violent criminals, gun traffickers, and other legally prohibited persons, as well as right-wing extremists. The country has also seen incidents of gunfire on school grounds and unintentional shootings by children involving ghost guns. [...] Decades ago, it may have required certain technical knowledge and skill to convert an unfinished frame or receiver into a fully functioning firearm, but those days are over. Prior to the ATF rule in 2022, with just a few tools and little time, a person with no gunsmithing skills could purchase an unserialized, unfinished frame or receiver without a background check and convert it into a working firearm. Without serial numbers, these guns are virtually impossible to trace when later recovered by law enforcement at crime scenes." Source: Everytown for Gun Safety

•      "Sold without background checks and serial numbers — unlike firearms sold by licensed manufacturers or importers — they’re almost impossible to trace. Ghost guns are especially dangerous because they are completely accessible to people who are legally prohibited from purchasing firearms, including minors. [...] Ghost guns have already been used in school shootings. In Santa Clarita, California, a 16-year-old brought a ghost gun to school. He used it to kill two of his classmates and injure three others before taking his own life." Source: Sandy Hook Promise
