Ghost Guns
Ghost Guns
What is the problem?
A ghost gun is a do-it-yourself, homemade firearm made from easy-to-get building blocks. These guns are made by an individual, not a federally licensed manufacturer or importer. In less than one hour, these self-made weapons become fully functioning, untraceable firearms.
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 2022.1Everytown Research analysis of US Department of Justice, “Justice Department Announces New Rule to Modernize Firearm Definitions,” press release, April 2022, https://www.justice.gov/opa/pr/justice-department-announces-new-rule-modernize-firearm-definitions; US Department of Justice, “FACT SHEET: Update on Justice Department ’s Ongoing Efforts to Tackle Gun Violence,” press release, June 2023, https://www.justice.gov/opa/pr/fact-sheet-update-justice-department-s-ongoing-efforts-tackle-gun-violence. Note: The ATF warns that “[t]he dramatic rise in trace submissions involving PMF’s reflects both increased criminal use of these firearms and enhanced awareness among law enforcement that ATF will process trace requests for PMFs. In particular, the substantial increase in PMF trace submissions since 2020 is in part attributable to education, outreach, and training that ATF has provided to LEAs on how to identify PMFs and the importance of submitting them for tracing.” 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.
Recent Federal Action
Federal authorities finalized a rule which took effect in August 2022 that clarified that the core building blocks of ghost guns are firearms under the law—ensuring they are traceable and that licensed dealers must conduct a background check before their sale. The rule updated and clarified key regulatory definitions, including “firearm,” “frame,” and “receiver,” to ensure that kits and components that are easily assembled into untraceable ghost guns are subject to the same regulations as firearms.1US Department of Justice and Bureau of Alcohol, Tobacco, Firearms and Explosives, “Definition of ‘Frame or Receiver’ and Identification of Firearms,” Federal Register 87, no. 80 (April 26, 2022): 24652–749, https://www.govinfo.gov/content/pkg/FR-2022-04-26/pdf/2022-08026.pdf.
This ATF rule has been challenged in court, and litigation is ongoing. In the event that the ATF rule is struck down, Congress must act to ensure that the core parts for ghost guns are defined as firearms and properly regulated. States should also consider additional action to regulate ghost guns.
WHAT DID THE ATF PREVIOUSLY NOT CONSIDER TO BE A FIREARM?
Prior to the federal rule in 2022, the ATF did not consider an unfinished frame or receiver—the basic building blocks of pistols and long guns, respectively—to be a firearm, even though the difference between an unfinished and a finished, ready-to-install frame or receiver is a few tools and very little handiwork.

Why is it an issue?
Criminals can easily build a gun in under an hour.
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.
Online sellers have tapped into this market, becoming one-stop shops for ghost gun parts, tools, and how-to guides, often openly promoting that their products are designed to evade ATF regulation. Following the finalization of the ATF rule, some ghost gun sellers shifted to offering 3-D printing files for frames and receivers along with the rest of the parts necessary to build untraceable guns. It should come as no surprise that ghost gun recoveries across the U.S. are on the rise, and have recently been connected with criminal enterprises, gun trafficking rings, and far-right extremists.
By the numbers
>25k
More than 25,000 privately made firearms were recovered by law enforcement agencies in 2022—a more than 1,300 percent increase from 2016.
1 hour
A person without gunsmithing skills can complete an unfinished frame or receiver with just a few tools and less than an hour of work.
2/3
More than ⅔ of the 80 online firearms sellers identified started selling ghost gun building blocks only within the past 5 years.
2,500
More than 2,500 ghost guns were connected to criminal activity in 114 federal cases from 2010 to April 2020.
What are the solutions?
-
Background checks are the foundation of any comprehensive gun violence prevention strategy. Current federal law requires that background checks be conducted whenever a person attempts to buy a gun from a licensed gun dealer. This is to ensure that the buyer is not legally prohibited from having the gun. Since federal law began requiring these background checks in 1994, background checks have blocked millions of sales to people with felony convictions or other prohibiting histories.
-
We need stronger policies, targeted interventions, and action from 3D-printing companies to combat the dangers of 3D-printed firearms.
