America is awash in gun manufacturers ─ yet few actually manufacture any guns.
According to the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF), the government agency charged with enforcing our nation’s federal gun laws, in 1975 the agency issued only 364 Type 07 Federal Firearms Licenses (FFLs), the basic federal license required to manufacture guns in America. By 2024, this number had soared to 20,566 ─ an increase of more than 5,550 percent.1

However, the majority of the “gun manufacturers” who possess the Type 07 license do not manufacture firearms in the commonly understood sense. Instead of a commercial manufacturing facility, they operate out of their homes, offices, or unrelated businesses ─ with a significant portion of license holders never even reporting the production of a gun to ATF.
For example, nationally in 2023,2 according to data contained in ATF’s Annual Firearms Manufacturers and Export Report (AFMER)3 and Federal Firearms Listing:4
- Eighty-one percent (16,236 of 19,997) of Type 07 license holders did not report producing any guns that year.
- Of the Type 07 license holders who did report producing guns that year, 54 percent (2,028 of 3,761) reported producing 10 or fewer firearms.
- Combined, Type 07 license holders who did not report producing any guns and Type 07 license holders who reported producing 10 guns or fewer that year represented 91 percent of all Type 07 license holders.
In Wisconsin in 2023,5 according to data contained in ATF’s Annual Firearms Manufacturers and Export Report (AFMER)6 and Federal Firearms Listing:7
- Eighty percent (317 of 397) of Wisconsin Type 07 license holders did not report producing any guns that year.
- Of the Type 07 license holders who did report producing guns that year, 53 percent (42 of 80) produced 10 or fewer firearms.
- Combined, Type 07 license holders who did not report producing any guns and Type 07 license holders who produced 10 guns or fewer that year represented 90 percent of all Type 07 license holders.
Nationwide, in just the five-year period from 2020 to 2024, the number of Type 07 FFLs increased by 40 percent ─ from 14,678 to 20,566 license holders.8

In Wisconsin for this same period, the number of Type 07 FFL holders increased by 49 percent ─ from 280 to 416 license holders.9

So, if a significant number of these license holders aren’t manufacturing guns, what are they doing? The honest answer is that no one really knows. But if history is any guide, most likely a significant portion are being used by license holders to evade a range of firearm regulations that apply to unlicensed private citizens.10
The Appeal of the Type 07 FFL
The Gun Control Act of 1968 (GCA) established the current federal licensing system for manufacturers, importers, wholesalers, and dealers of firearms. Under the GCA, any person “engaged in the business”11 of making or selling firearms must be licensed by ATF.12
The ATF graphic below describes the nine types of Federal Firearms Licenses (FFLs) issued by the agency.

Both the Type 01 FFL dealer’s license (the basic license to sell firearms other than destructive
devices13) and the Type 07 FFL manufacturer’s license (the basic license to manufacture firearms other than destructive devices) exempt the license holder from many of the restrictions on the sale and transfer of firearms that private citizens are subject to under the Gun Control Act. Unlike ordinary citizens, these license holders can:
- buy and sell firearms in interstate commerce and receive firearms via common carrier;
- purchase firearms from wholesalers at discount and in unlimited quantities; and,
- bypass requirements that apply to unlicensed individuals, such as background checks.
In addition, by paying an annual “Special Occupancy Tax” (SOT) a Type 07 license holder, in addition to manufacturing standard firearms, can also manufacture weapons and firearm accessories that come under the more restrictive regulations of the National Firearms Act of 1934 (NFA), such as fully automatic machine guns and firearm silencers.

According to the “federal firearms license experts” at FFL123,14 a commercial site that sells online kits available to private citizens who want to obtain an FFL (most likely for personal use):
The Type 07 FFL is the most powerful and popular FFL to get. With it you can do everything a Type 01 FFL can (buy, sell and repair firearms) plus manufacture guns and ammo. When you add a…SOT to this license you can also make NFA items like silencers and even machine guns!15
The fee for a Type 07 FFL is $150 to apply and $150 to renew every three years. The annual fee for the Type 02 Special Occupancy Tax (SOT) is $1,000 per year.16
FFL123 also promotes the Type 07 license with an SOT as a way for the license holder to undercut the 1986 ban on the private possession of new machine guns. In May 1986, Congress banned the production of new machine guns for civilian sale (private citizens can, however, purchase pre-1986 machine guns under federal law if they meet the heightened sale and possession standards of the NFA as well as state and local laws). The Type 07 license (like the Type 01 license) combined with the SOT allows the possessor access to new, post-1986 machine gun “samples,” ostensibly for law enforcement or similar sales or review.17
As FFL123 trumpets, “In fact, this is the most common way to gain access to post May 1986 machine guns and combine business with pleasure!”18
However, with the Type 07 license, the license holder can also build their own machine gun for what can be, in reality, personal use. In a July 2021 blog titled “Who Can Own a Full-Auto Machine Gun?,” FFL123 owner Brandon Maddox ─ noting, “You might think that this sounds shady, but it’s not” ─ enthusiastically answers his own question as seen in the extended quote below:
Who can own a full-auto machine gun? Well, the simple answer is: you! You can own a machine gun. Yes, that’s right. It’s perfectly legal for you to own a machine gun! They are not some mythical object made up of Unobtainium…
Under current law, only government agencies can acquire newly-made machine guns ─ but they still need dealers to buy them from and manufacturers to make them.
Sales of such guns go through FFL gun dealers with either an 03 SOT (retail sales of NFA items with an 01 or 02 FFL) or an 02 SOT (manufacturing of NFA items with an 07 or 10 FFL).
Here’s where it gets interesting…
An 03 SOT needs a letter from a law enforcement agency asking to see a particular machine gun demonstrated. This is called a demo letter, and the gun is called a dealer sample. Only 02 and 03 SOTs can acquire dealer samples, and only with a demo letter. Once you allow the agency to examine the gun, it is yours to keep as long as you maintain your SOT. Many SOT holders acquire demo guns from friendly local law enforcement requests.
However, if you cannot get a demo letter, an 03 SOT gun dealer has no other way of acquiring a machine gun. If you are an 02 SOT, though, you are legally allowed to build as many machine guns or other NFA devices as you wish (following a certain procedure, of course) and may retain them for as long as you maintain your SOT.
That’s right: you can build a machine gun (full-auto machine gun) legally and keep it for as long as you wish and are in business!
Too Good to Be True?
You might think that this sounds shady, but it’s not. As long as you are conducting legal business, there are all sorts of reasons to build legal machine guns, including proof of concept, experimentation, range rentals, demo guns, movie prop rentals, and more. Along the way, as an incidental to doing business, there is absolutely nothing wrong with enjoying the machine guns you have built or acquired. In fact, it would be stupid not to do so!19
FFL123 also notes that “ATF inspectors can only come to inspect during ‘business hours.’ They can only inspect once every 12 months. Do not expect an inspection but once every 20 years, as we understand that is their average.”20
This is not an exaggeration. For fiscal year 2024, only eight percent of all FFL holders (9,696 out of 127,784) were subject to ATF firearm compliance inspections.21 These 9,696 compliance inspections resulted in recommendations that included: report of violations, 1,689; warning letter, 721; warning conference, 214; license surrendered/out of business, 1,488; revocations, 195. No violations were reported for 5,207 license holders.22
By 2026, this already low percentage of ATF compliance inspections (eight percent) will likely drop even further. According to the Department of Justice’s recently released budget summary, 541 of ATF’s Industry Operations Investigators (IOIs) ─ the personnel responsible for carrying out these inspections ─ are slated to be eliminated by fiscal year 2026. In the budget summary, ATF explains that this will result in a reduction of “ATF’s capacity to regulate the firearms and explosives industries by approximately 40 percent in FY 2026.”23 In fact, this may be an underestimate. In March 2025, ATF reported that there were 857 Industry Operations Investigators; eliminating 541 of them would be a reduction of nearly two-thirds.24
With federal oversight significantly diminished, any regulatory effort will have to be at the local or state levels. This includes any and all zoning laws, business licensing requirements, related fees, and regulations.
The stark reality is that in states across America ─ including Wisconsin ─ an unknown number of communities are home to “kitchen-table” gun manufacturers that are mostly hidden from public view, as the information contained in the next section vividly illustrates.
The Gun Manufacturer Next Door
For this study, the VPC conducted a series of analyses of the state’s 397 Type 07 license holders in 2023. As part of this process, the VPC identified Wisconsin gun manufacturers who reported producing no guns that year or who reported producing fewer than 10 guns that year. While only a snapshot for a specific period in time, the data offers a window into the prevalence of Type 07 license holders in residential areas in the state. As of September 2025, ATF’s list of FFL license holders still lists the pictured structures below as the license holder’s place of business.
The review revealed that while the majority of FFL holders’ place of business appear to be non-residential structures, a not insignificant portion appear to operate out of homes, in a residential neighborhood, with no easily discerned signage. It is highly unlikely that the presence of the manufacturer would be known by local residents or passersby from sight alone. Other sites include unrelated commercial entities.
The hidden nature of these gun manufacturers is all the more important keeping in mind the unique privileges granted the Type 07 license holder as detailed throughout this report.
The silent majority: zero reporting manufacturers
In 2023, 80 percent of Wisconsin’s Type 07 FFL holders (317 of 397) reported no firearm manufacturing activity. While they appear on the Federal Firearms Listings, they are absent from the Annual Firearms Manufacturers and Export Report (AFMER). As part of its research on Type 07 FFLs, the Violence Policy Center developed an online tool that allows the user to enter their home (or any) address to see if there are any Type 07 federally licensed gun manufacturers near them. The tool employs Google Earth to allow the user to see a photograph of any structures located at the address of the license holder’s place of business. (The tool also allows the user to search for Type 01 gun dealer license holders.) The tool can also be used to identify license holders by state or zip code.
Using this tool, the VPC examined the publicly listed addresses of all the non-reporting license holders. From this survey, it appeared that nearly 40 percent claimed a residential property as their licensed premises.
The collage below offers a sample of zero-reporting manufacturers where it appears that they are listing a residential structure as their place of business.

Home-based manufacturers in Wisconsin
In 2023, the VPC found that only 20 percent (80 of 397) of Type 07 license holders in Wisconsin reported manufacturing any guns that year. Of the license holders who did manufacture guns, 42 of the 80 (53 percent) manufactured 10 guns or fewer.
For this group of 42, using the VPC’s online tool, we researched each license holder’s publicly available address to identify the structure associated with the license holder’s place of business.
We found that 55 percent (23 of 42) appeared to be operating out of a residential structure.
Below is the place of business for MILWAUKEE TACTICAL LLC, which manufactured three rifles in 2023 and is located in Milwaukee, Wisconsin.

Below is the place of business for GENESIS CUSTOM GUNSMITHING LLC, which manufactured one 22 caliber pistol in 2023 and is located in Plymouth, Wisconsin.

The slideshow below shows the place of business for Wisconsin Type 07 license holders who manufactured 10 or fewer firearms and appear to operate out of a residential structure.
More than 10 firearms
In addition, when looking at Type 07 FFL holders who manufactured more than 10 firearms, 29 percent (11 of 38) appeared to be operating out of a residential structure.

Altogether, nearly 43 percent (34 of 80) of all Type 07 license holders who reported manufacturing guns in 2023 appeared to be operating out of a residential structure.

Wisconsin Regulations
As in other states, the first step to becoming a firearms manufacturer in Wisconsin is to obtain a Type 07 Federal Firearms License (FFL). Federal law requires that applicants for any FFL must certify that their business will comply with all applicable state and local laws, and certify that:
The business to be conducted under the license is not prohibited by State or local law in the place where the licensed premise is located; within 30 days after the application is approved the business will comply with the requirements of State and local law applicable to the conduct of the business; and the business will not be conducted under the license until the requirements of State and local law applicable to the business have been met; and that the applicant has sent or delivered a form to be prescribed by the Attorney General, to the chief law enforcement officer of the locality in which the premises are located, which indicates that the applicant intends to apply for a Federal firearms license.25
According to FFL123, Wisconsin is “kind to gun owners and gun businesses,”26 extolling:
Wisconsin is a wonderful place to be an FFL! While the population is somewhat small, gun ownership is very popular and common. There are plenty of places to set up business with your Wisconsin FFL, and it is a fantastic state to have a home based FFL.
Wisconsin has very few limits on NFA items as well. Other than some odd machine gun rules, a Wisconsin FFL licensed to sell NFA items can sell pretty much anything they want. This includes the ever growing market for silencers, which can be a fantastic. [sic]
Part of meeting the requirements of state and local law is complying with zoning requirements. As FFL123 competitor RocketFFL notes:
Local zoning requirements are sometimes an issue when applying for an FFL.
I can not stress enough the importance of making sure the location you use as a base of operations (often a home-based FFL) allows for a business. It’s common for a home-based firearms business to be told you can’t operate in a residential area.27
FFL123 adds:
Wisconsin has a lot of small towns and rural areas with less restrictive zoning regulations than developed population centers. That means if you want to get a home based FFL in Wisconsin, it should be pretty easy.28
While Wisconsin does not require a state license for FFLs, there is a requirement to register with the state.
For this report, the VPC utilized Wisconsin’s One Stop Business Portal database to identify Type 07 license holders that were registered as businesses with the state.29
As noted earlier, there are 397 Wisconsin Type 07 license holders listed on ATF’s final Federal Firearms Listing for 2023. These 397 license holders represent all Type 07 licensees in Wisconsin for that period, whether they were manufacturing firearms or not.
Of the 397 Type 07 FFL holders identified in 2023, the VPC found that 256 appeared to be registered and in good standing with the state as of October 2025. Of the remaining 141 Type 07 FFL holders, 73 did not appear to be actively registered, and 68 were not found by the VPC in the Wisconsin One Stop Business Portal database.30
In addition, there is a separate dealer registration requirement.31 Before an FFL can offer a handgun for sale or initiate an approval for the transfer of a handgun, a dealer must register each handgun store the dealer owns or operates with the Wisconsin Department of Justice.32
There is also a product safety warning requirement. The sale or transfer of any firearm must be accompanied by the following warning:
IF YOU LEAVE A LOADED FIREARM WITHIN THE REACH OR EASY ACCESS OF A CHILD YOU MAY BE FINED OR IMPRISONED OR BOTH IF THE CHILD IMPROPERLY DISCHARGES, POSSESSES OR EXHIBITS THE FIREARM.33
Is There a Gun Manufacturer Next Door to You?
As noted earlier, in conjunction with its research on the illegitimate possession of Type 07 FFLs, the Violence Policy Center developed an online tool that allows the user to enter their home (or any) address to see if there are any Type 07 federally licensed gun manufacturers near them. The tool also allows the user to search for Type 01 gun dealer license holders. The tool can also be used to identify license holders by state or zip code.

Conclusion and Recommendations
The proliferation of Type 07 license holders who do not manufacture firearms raises serious public safety concerns. Our research reveals that a significant number (both nationally and in Wisconsin) do not manufacture any firearms. This leads to the natural question of for what purpose do they possess the license? If history is any guide, one answer may be that a significant proportion of licensed manufacturers obtained the Type 07 license to exploit the privileges granted to licensees rather than to operate a legitimate business. While this alone is worthy of further investigation, the fact that a significant number of manufacturers are located in residential areas makes finding answers to this basic question imperative. Potential state and local recommendations that could be applied to Wisconsin are listed below.
State and Local Recommendations
- State and local jurisdictions should review FFL holders in their state/community to ensure that they are in compliance with all tax, zoning, business licensing laws, and other relevant regulations.
- States, and where possible local jurisdictions, should implement new standards for manufacturers to decrease the number of Type 07 license holders who have obtained the license for personal use.
- States should establish manufacturer licensing requirements, including the authority to routinely inspect license holders.
- A registry of Type 07 FFL holders should be available, preferably in map form, on local government websites to further inform the public of firearms manufacturing and exporting within residential and other sensitive areas.
Federal Recommendations
- The fees for a Type 07 manufacturer’s license should be increased significantly. The fees for the Special Occupancy Tax (SOT) should also be increased. The fees should also be indexed for inflation.
- Repeal the current restrictions limiting the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) to one inspection in a 12-month period and allow ATF to conduct routine inspections of licensed manufacturers.
- The issuance of Type 07 manufacturers’ licenses should be restricted to entities with locations zoned for industrial activities. No licenses should be issued to persons operating from residential locations.
- Manufacturers should be required to routinely submit proof to federal, state, and local authorities demonstrating that the manufacturing facility is in compliance with all applicable zoning laws.
- ATF should ensure that all manufacturers are supplying accurate reports of firearm production and export.
- Further research should be conducted examining the practice of Type 07 license holders with an SOT obtaining or building new machine guns for government agencies (for example, local law enforcement) when, in fact, the weapons are obtained/manufactured for personal use by the license holder.

The 1992 Violence Policy Center study More Gun Dealers Than Gas Stations revealed that from 1975 to 1992 the number of Type 01 FFLs ballooned from 146,429 to 245,000 ─ an increase of 67 percent. The licenses were so easily obtained from ATF that at the time of the study’s release the number of Americans who possessed a Type 01 FFL was greater than the number of gas stations across the nation: 245,000 compared to 210,000. The bulk of the licenses were held by “kitchen-table” dealers. These license holders operated out of their homes or offices, as opposed to storefront gun dealers (commonly known as “stocking dealers”). Of these kitchen-table dealers, an unknown percentage were actively involved in criminal gun sales as well as illegal firearms trafficking.
In response to the widespread abuse of Type 01 FFLs and at the urging of the Violence Policy Center, the Clinton Administration began strictly enforcing the requirement that license holders be “engaged in the business” of selling firearms as required by federal statute. In addition, the 1994 Brady Law implemented many of the recommendations the VPC laid out in its 1992 study. Additional requirements were contained in the 1994 Violent Crime Control and Law Enforcement Act. Heightened ATF scrutiny, both at the time of issuance and renewal, sent a message to the firearms community (both law-abiding and criminal) that the days when a dealer’s license could be obtained with virtually unquestioned ease had come to an end. At the same time, state and local jurisdictions began focusing on kitchen-table dealers via a wide range of enforcement mechanisms (e.g., instituting their own standards for license eligibility, enforcing zoning and business laws, and conducting onsite inspections of licensees’ place of business). As a result of these enforcement efforts, the number of Type 01 FFLs in the United States has dropped 78 percent ─ from 213,734 in 1994 to 47,267 in 2024. In 2024, the Biden Administration implemented a rule to force more people to obtain gun dealer licenses. The measure was intended to enhance safety, yet the question remained whether the unintended consequence would be a return to the days when there were more gun dealers than gas stations and corrupt gun dealers were associated with a high volume of illegally trafficked firearms. In April 2025, under the Trump Administration, the Department of Justice and the Bureau of Alcohol, Tobacco, Firearms and Explosives announced a review of “Final Rule 2022R-17F, related to the definition of ‘engaging in the business’ of firearms dealing.”
- The term “engaged in the business” means “a person who devotes time, attention, and labor to manufacturing firearms as a regular course of trade or business with the principal objective of livelihood and profit through the sale or distribution of the firearms manufactured.” 18 USC § 921(a)(21).
- 18 USC § 922 (a)(1).
- 26 USC §5845(f) defines the term “destructive device” as “(1) any explosive, incendiary, or poison gas (A) bomb, (B) grenade, (C) rocket having a propellent charge of more than four ounces, (D) missile having an explosive or incendiary charge of more than one-quarter ounce, (E) mine, or (F) similar device; (2) any type of weapon by whatever name known which will, or which may be readily converted to, expel a projectile by the action of an explosive or other propellant, the barrel or barrels of which have a bore of more than one-half inch in diameter, except a shotgun or shotgun shell which the Secretary finds is generally recognized as particularly suitable for sporting purposes; and (3) any combination of parts either designed or intended for use in converting any device into a destructive device as defined in subparagraphs (1) and (2) and from which a destructive device may be readily assembled.”
