A ghost gun is a homemade or privately made firearm assembled by an individual from parts or kits, often purchased online without background checks or serial numbers. These guns are untraceable because they lack serial numbers, making them invisible to traditional firearm tracking and regulation systems
. Ghost guns can be built from nearly finished components called "80 percent receivers," which require minimal machining to become functional firearms. They can also be produced using 3D printing technology, sometimes almost entirely printed at home
. The assembly process is relatively simple, often requiring only basic tools like a drill, and is supported by widely available instructional videos and kits marketed for easy DIY construction
. Because ghost guns bypass federal regulations that apply to licensed firearm manufacturers and dealers, they can be obtained without background checks, increasing the risk of access by prohibited individuals, including minors
. Law enforcement faces challenges tracing these firearms due to the lack of serial numbers, complicating investigations and crime-solving efforts
. Ghost guns have been involved in several high-profile shootings, highlighting their public safety concerns. Their ease of production and anonymity have also led to illegal manufacturing rings capable of producing large quantities of untraceable firearms
. In summary, ghost guns are untraceable, homemade firearms assembled from parts or kits, often without regulatory oversight, posing unique challenges to gun control and law enforcement
