Thousands of ads on Facebook and Instagram have promoted “fuel filters” using videos demonstrating how they can be easily modified into gun silencers—a process that, without federal approval, could lead to felony charges. Despite Meta’s policies banning ads for silencers on the company’s social networks, the promotions have persisted for years, driven by a what appears to be a single network of more than 100 Facebook pages marketing “fuel filters” that can be easily turned into gun silencers, WIRED has found. The devices sell for as little as $50.
Silencers, also known as suppressors, are heavily regulated under United States federal law. Purchasing one legally requires submitting fingerprints, passing a background check, and paying a fee to the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF). Federal law allows people to build their own suppressors, provided they register the device with the ATF. But the ads don’t mention this key stipulation, marketing silencers to buyers who may not understand the legal risks.
“You know those things that are definitely not suppressors, even though they look just like suppressors,” a man says in a video that appears in many of the ads. “Well, but they’re still not suppressors, because they don’t have a hole in the other end. So, you can legally own one without going through the paperwork to own a suppressor, because it isn’t one.”
The ads often recycle the same text, referencing “light and durable air-grade aluminum,” and use videos stitched together from a handful of YouTube clips featuring firearms influencers and enthusiasts. The original creators of these videos are likely unaware their content is being used; one tells WIRED they had deleted the footage from YouTube years ago.
One ad features a suppressor engraved with the words Black Collar Arms. A co-owner of Black Collar Arms, who goes by Jeremy McSorely, tells WIRED his company has no connection to the ad. McSorely explains that the footage was taken from a blog and YouTube video he had uploaded years ago but has since removed. “The photos you saw were screenshots taken from my video,” he says, emphasizing that the suppressor was legally manufactured and engraved with their corporate information to comply with ATF regulations.
In November 2023, the ATF warned federal firearms licensees about marketing silencers as “solvent traps,” or contraptions purportedly used to collect gun oil and residue during cleaning. The agency clarified that legality depends on functionality, not what you call a product, and stressed that even incomplete parts intended for silencers are regulated under federal law.
“The test for whether an item is a silencer is not the label a manufacturer or retailer applies.
Rather, it is the way the statute written by Congress applies to the item,” the ATF wrote, referring to definitions of suppressors in the Gun Control Act and the National Firearms Act.
A WIRED analysis of more than 2,800 ads revealed they are linked to a network of hundreds of ecommerce websites. These sites often reuse code, share IP addresses, and peddle the same low-quality knockoff products alongside the “fuel filters.” At least one of the sites was flagged by Google as a likely phishing scam.
Experts believe the operation is based in China and relies on a drop-shipping scheme. “It’s likely just a reshipper selling controversial or illegal products,” says Zach Edwards, a senior threat researcher at cybersecurity firm Silent Push who specializes in online data ecosystems.
Typically, Edwards explains, drop-shippers wait for a customer to place an order, then purchase the item from inexpensive online retailers, repackage it, and ship it to the customers. Edwards says that the operator behind the network is likely creating hundreds of websites, applying a moderate markup to the products, and spinning up Facebook pages to promote their items. “Even if some sites or ads get caught and taken down, others keep running,” Edwards says. “It’s a spray-and-pray method.”
Meta explicitly bans ads promoting weapons, silencers, and related modifications. According to Meta, ads are reviewed by an automated system with support from human moderators. However, enforcement has been inconsistent: While at least 74 of the ad campaigns in our analysis were removed for violating the platforms’ terms, the rest appeared to have run successfully.
After WIRED reached out to Meta, the company said that it removed the ads and associated advertising accounts. However, a quick search of Meta’s Ad Library revealed that nearly identical ones have since been published.
“Bad actors constantly evolve their tactics to avoid enforcement, which is why we continue to invest in tools and technology to help identify and remove prohibited content,” Meta spokesperson Daniel Roberts wrote in a statement.
Roberts says that many of the ads flagged by WIRED had little to no engagement, suggesting few people ever saw this content. However, at least two ads reviewed by WIRED had thousands of comments, including accusations that it was an ATF honeypot, complaints from self-identified buyers whose products never arrived, and even testimonials from others claiming the item worked as advertised. WIRED reached out to several commenters who said they had purchased the product—none responded.
The ads have also drawn the attention of US Department of Defense officials. An internal presentation to Pentagon staff, viewed by WIRED, claims that the targeted ad for a fuel filter had been served to US military personnel on a government computer at the Pentagon. The presentation, which a source says was delivered to high-ranking general officers, including the US Army’s chief information officer, raised flags over how social media algorithms are being used to target service members.
Meta’s Ad Library provides limited transparency, leaving it unclear exactly how these ads are targeted. Researchers suggest that Meta’s powerful ad tools, which allow advertisers to find niche audiences using granular targeting options, could be exploited to reach gun enthusiasts or military personnel. While Roberts confirmed that Meta did not detect any indication that these ads were targeting the military, WIRED found that advertisers can easily target users who list their job title as “US Army” or “military” on their profiles—an audience that Meta estimates includes up to 46,134 people.
Meta’s platforms have long struggled to prevent the sale of firearms and related products. An October 2024 joint report by the Tech Transparency Project found that more than 230 ads for rifles and ghost guns had run on Facebook and Instagram in nearly three months. Many of these ads directed buyers to third-party platforms like Telegram to complete transactions. In 2024, two Los Angeles County men were charged with operating an “unlicensed firearm dealing business” that used Instagram accounts to advertise and market the sale of more than 60 firearms, which included some untraceable ghost guns and weapons with scratched-off serial numbers. Both individuals have since pleaded guilty.
Silencers are rarely used in crimes, but their use is on the rise—nearly 5 million are registered in the United States, up from 1.3 million in 2017. Last month, 26-year-old software engineer Luigi Mangione allegedly used a 3D-printed gun equipped with a silencer to fatally shoot UnitedHealthcare CEO Brian Thompson on a street in midtown Manhattan.
