Lawmakers Push to Halt Public Sales of Ammunition from U.S. Army Plant

Democratic lawmakers have introduced legislation to restrict the sale of high-caliber ammunition and assault weapons to the public when those products are manufactured at government-owned facilities like the Lake City Army Ammunition Plant. The move comes after a joint investigation by the International Consortium of Investigative Journalists (ICIJ) and the New York Times revealed that .50-caliber ammunition produced at the plant has been diverted to Mexican drug cartels, fueling violence south of the border. This legislation aims to close a loophole that allows U.S. Tax dollars to potentially contribute to criminal activity and instability.

Investigation Uncovers Ammunition Trafficking

The impetus for this renewed legislative effort stems from an ICIJ investigation published in February 2026. The reporting detailed how .50-caliber ammunition, manufactured at the Lake City Army Ammunition Plant in Missouri, has been trafficked to Mexican cartels. These cartels have then used the powerful ammunition – capable of penetrating armored vehicles – to escalate violence against the Mexican government and civilians. Mexican Defense Minister officials stated that nearly half of the .50-caliber ammunition seized by the Mexican government bore the Lake City mark.

What the Bill Proposes

The proposed legislation, co-sponsored by Senators Elizabeth Warren and Andy Kim, and Representatives Robert Garcia and Jamie Raskin, would specifically ban defense contractors and government-owned plants, such as Lake City, from selling high-caliber ammunition and assault weapons to civilians. Senator Warren emphasized that “Americans’ tax dollars should not be used to fuel gun violence,” framing the bill as a necessary step to enhance public safety and prevent the unintended consequences of current manufacturing practices.

Lake City: A Unique Case

The Lake City Army Ammunition Plant is the largest producer of rifle rounds for the U.S. Government and its allies, having produced billions of rounds. Yet, it operates under a unique arrangement. While owned by the U.S. Government, the plant is operated by private contractors. These contractors are permitted to manufacture products for the commercial market, a practice intended to reduce costs for the military and ensure the plant’s continued operation even during periods of lower military demand. This arrangement has allowed for the sale of .50-caliber ammunition, designed for military use and with limited civilian application, on the open market.

The Cartel Connection: A Growing Threat

The ICIJ investigation identified at least 16 online retailers in the U.S. That have sold the .50-caliber ammunition, despite previous attempts to restrict its availability. Cartel gunmen have utilized this ammunition to down helicopters, assassinate government officials, and attack both police and military forces, as well as civilians. The investigation also found instances of Lake City casings recovered at crime scenes linked to cartel violence, including one case where armor-piercing ammunition penetrated an armored vehicle, resulting in casualties.

Political Divide and Past Efforts

The issue has drawn a clear political divide. Republican officials have argued that the commercial production arrangement at Lake City is vital for national security and ensures a readily available supply of affordable ammunition for the public. In 2024, 28 Republican attorneys general sent a letter to then-President Joe Biden opposing efforts to halt commercial production at the plant, asserting the need to prioritize national defense and the Second Amendment. Previous attempts by Democratic lawmakers to introduce similar legislation have stalled without a vote. The current sponsors express hope that the recent investigative findings will create renewed momentum for the bill’s passage. Congressman Robert Garcia stated, “We should not live in a world where weapons and ammunition sold by the government end up in the hands of violent criminals and are used to devastate our own communities.”

What Happens Next?

The bill now enters the legislative process, where it will face committee hearings, potential amendments, and a vote in both the House and Senate. Its success will depend on securing bipartisan support and navigating the complex political landscape surrounding gun control and national security. The outcome remains uncertain, but the recent spotlight on the issue, fueled by the ICIJ investigation, has significantly raised the stakes. The Financial Crimes Enforcement Network (FinCEN) is also currently seeking public comments on a proposed delay to an anti-money laundering rule, which could have implications for tracking the flow of funds related to ammunition sales, as reported by The FACT Coalition.
