Ghost guns are firearms that lack serial numbers, making them untraceable.
Typically, these guns are assembled using kits or unfinished components like frames or receivers that are not regulated under federal law until they are completed. Once assembled, ghost guns function like traditional firearms and can be just as lethal.
These firearms have appealed to individuals who wish to bypass background checks or firearm regulations, including those prohibited from owning guns. While ghost guns are not inherently illegal, their unregulated nature before assembly creates loopholes in existing gun laws.
Frames and receivers—the core components of firearms that house the firing mechanism—are regulated under federal law. However, when these parts are sold in an unfinished state, they historically did not meet the legal definition of a firearm, allowing them to be sold without serial numbers, background checks, or dealer licenses. This regulatory gap meant:
No restrictions on who could buy ghost gun kits or parts.
No limitations on the quantity someone could purchase.
Circumvention of state-level regulations like age restrictions, waiting periods, and licensing.
This loophole contributed to the rise in ghost gun availability and usage in criminal activities.
Tools like a drill or drill press are usually sufficient to complete an unfinished frame or receiver. Reports suggest that assembling a ghost gun can take less than an hour, making them accessible to almost anyone.
Ghost guns have seen a dramatic rise in circulation over the past decade. According to the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF), law enforcement agencies recovered over 19,000 privately made firearms (PMFs) in 2021—up from just 1,600 in 2017.
This growth reflects the increasing popularity of 80 percent lowers, DIY gun kits, and 3D-printed components among hobbyists and home builders.
Industry analysts estimate that tens of thousands of un-serialized firearms are built each year, with many sold at gun shows or online prior to recent regulatory changes.
The surge in production has prompted lawmakers and regulators to re-examine how these weapons fit into the broader gun policy landscape.
The controversy surrounding ghost guns stems from their untraceable nature and accessibility. Law enforcement agencies report significant increases in ghost gun recoveries at crime scenes.
Ghost guns undermine gun laws by allowing individuals to bypass background checks and other legal safeguards. Critics argue that this creates significant risks to public safety and hampers law enforcement’s ability to solve crimes.
In August 2022, the Biden administration enacted a rule requiring ghost gun kits and some components to be serialized, sold by licensed dealers, and subject to background checks. This rule aimed to:
Classify ghost gun kits as firearms under federal law.
Ensure that unfinished frames and receivers meet the same regulatory standards as completed firearms.
Reduce the availability of untraceable firearms in the market.
Several states and cities have implemented additional measures to regulate ghost guns. These include banning the manufacture, sale, and possession of unserialized frames and receivers.
States like California, New York, and Maryland have enacted laws to close loopholes and enhance tracking of firearms.
Cities like Los Angeles, Philadelphia, and Washington, D.C., have also passed ordinances to combat the spread of ghost guns.
Two notable bills addressing ghost guns include:
The Ghost Guns and Untraceable Firearms Act : Introduced in 2023, this bill aims to define ghost guns under federal law and ban their manufacture, sale, and possession.
The 3D Printed Gun Safety Act : This bill seeks to prohibit the distribution of blueprints for 3D-printed firearms, preventing the unregulated production of ghost guns using 3D printers.
Ghost guns pose several risks:
Increased Crime: Their untraceable nature makes them appealing to criminals.
Youth Accessibility: Without background checks, minors can acquire components.
Law Enforcement Challenges: The lack of serial numbers complicates crime investigations and gun tracking.
The 2022 ATF rule on ghost guns has faced legal challenges from firearm manufacturers and advocacy groups. The Supreme Court case Garland v. VanDerStock is expected to address the validity of these regulations. The outcome could have significant implications for the federal government’s ability to regulate ghost guns.

Ghost guns are untraceable firearms that lack serial numbers, making them difficult to track in traditional databases. These firearms are often assembled from kits or unfinished components and are not subject to the same regulations as factory-produced firearms until completed.
In the firearms industry, a ghost refers to the untraceable nature of a firearm due to its lack of a serial number. These weapons are often referred to as ghost guns because they do not leave a traceable record, complicating law enforcement efforts to track their ownership or use.
Traditional guns are manufactured with serial numbers and are regulated under federal and state laws, requiring background checks and dealer licensing for purchases. Ghost guns , on the other hand, can be assembled privately and often bypass these regulations, making them untraceable and unregulated.
Building a ghost gun typically requires basic tools such as a drill, a drill press, and a few hand tools. Kits often include detailed instructions and templates, enabling individuals with minimal technical skills to assemble a fully functional firearm.
Ghost guns are considered dangerous weapons because they are untraceable and accessible without background checks. This makes them appealing to individuals prohibited from owning firearms, such as convicted felons, and poses significant risks to public safety.
Made firearms refer to firearms that are privately manufactured, often from kits or components. Many ghost guns fall under this category because they are assembled outside the traditional regulatory framework. These made firearms bypass the serialization and tracking that govern commercially produced firearms.
Efforts to regulate ghost guns have increased in recent years. Federal rules enacted in 2022 classify certain kits and components as firearms, requiring serialization, background checks, and sales through licensed dealers. These measures aim to ensure that ghost guns regulated meet the same standards as traditional firearms.
No, not all guns are regulated equally. Traditional firearms are subject to stringent federal and state laws, including serialization and background checks. Ghost guns , until recently, operated outside these regulations, leading to increased scrutiny and new rules aimed at bringing them into compliance.
The Brady Campaign to Prevent Gun Violence strongly advocates for stricter regulations on ghost guns . They view these untraceable firearms as a significant threat to public safety and support legislation to close loopholes that allow individuals to bypass standard gun control measures.
Traditional firearms are manufactured by licensed companies and include serial numbers for tracking purposes. In contrast, ghost guns are privately assembled and lack serialization, making them difficult to trace and easier to obtain without oversight.
A 3D printed gun is a firearm that’s created using a 3D printer and digital blueprints—usually made from plastic or polymer-based materials. Some models include metal parts for durability, but many are entirely printed. While not all 3D printed guns are ghost guns, they often lack serial numbers and can be manufactured without regulation, raising similar legal and public safety concerns. The ease of downloading files and printing parts at home has alarmed lawmakers and law enforcement alike.
An 80 percent lower refers to an unfinished lower receiver (for AR-style rifles or pistols) that is 80% complete—meaning it cannot yet function as part of a firearm. Because it's not legally considered a firearm until finished, it can be sold without serial numbers or background checks. Once completed, it becomes a key component of a working gun. These parts are a common starting point for building ghost guns and are now more heavily regulated under recent ATF rules.
Yes, under federal law, building a homemade gun for personal use is legal—as long as the builder is not prohibited from owning firearms and does not intend to sell or transfer the gun. However, some states have stricter rules, requiring serialization, registration, or outright banning self-made guns. The issue becomes more complicated when those firearms are built without serial numbers or sold illegally.
A DIY gun (do-it-yourself gun) is a general term for any firearm built by an individual outside of a licensed factory setting—usually from parts, kits, or raw materials. Ghost guns are a specific type of DIY gun that lacks a serial number and was built without going through a legal transfer process. While all ghost guns are DIY guns, not all DIY guns are ghost guns. Some homemade firearms are legally built and properly serialized.
