US Democratic Party proposes bill to ban private sales of military ammunition

Democratic lawmakers have proposed a federal bill that would ban private sales of high-caliber ammunition produced by defense companies and government-owned factories. The bill, co-sponsored by Senators Elizabeth Warren (Massachusetts) and Andy Kim (California), and Representatives Robert Garcia (Calif.) and Jamie Raskin (Maryland), would also ban Department of Defense contractors from selling assault weapons to the general public.

“Americans’ tax dollars should not be used to fuel gun violence,” Warren said in a statement. “Congress must stop the U.S. military and large defense contractors from selling weapons of war to cartels, criminal organizations, and mass murderers.”

How the Lake City Factory Became a Source of Cartel Arming

This legislative attempt originated from joint investigative reporting by the International Consortium of Investigative Journalists (ICIJ) and the New York Times. Investigations show that .50 caliber ammunition produced at the U.S. Army-owned Lake City Army Ammunition Plant is being smuggled into Mexican drug cartels and used in armed conflicts against the Mexican government.

The Lake City plant, located outside Kansas City, Missouri, is the largest rifle ammunition production facility for the U.S. government and its allies. The plant has produced billions of rounds of ammunition, a significant amount of which has been sold to the civilian market. This includes .50 caliber ammunition the size of a medium cigar, which has the power to penetrate even armored vehicles.

.50 caliber ammunition was originally designed for military use and has very limited civilian use. However, the ICIJ investigation revealed that the cartel was purchasing large quantities of ammunition from private dealers in the United States and then smuggling them into Mexico.

The scary reality of cartel violence

Cartel militants armed with .50-caliber firearms have shot down helicopters, assassinated government officials, opened fire on police and military personnel, and massacred civilians. In February of this year, Mexico's Defense Minister told reporters that nearly half of the .50-caliber ammunition seized by the Mexican government bore the Lake City engraving.

ICIJ has identified at least four cases in which .50-caliber shell casings from Lake City were found at crime scenes linked to cartel violence. In one incident, an armor-piercing round produced at the plant penetrated an armored vehicle, killing one crew member and injuring three others.

The investigation found that at least 16 online retailers in the U.S. are continuing to sell this ammunition despite previous attempts by Congress to regulate it. Lake City also produces small-caliber ammunition for the AR-15 semi-automatic rifle, which is frequently found at AR-15-related crime scenes in the United States.

Background to private sales: reducing costs and sustaining production

The Lake City plant is owned by the U.S. government but operated by a private contractor. The U.S. Army has signed agreements to allow contractors to produce products for the commercial market to keep factories running even when military demand declines and to reduce military procurement costs.

Republicans argue that the system is essential both to national security and to providing affordable ammunition. In a 2024 letter to then-President Biden, Republican attorneys general from 28 states opposed Lake City's attempt to halt commercial production, writing, "Our country should focus on preparing for foreign hostile forces rather than destroying the Second Amendment and crippled firearms and ammunition markets."

Past failures and prospects for this bill [AI analysis]

Democratic lawmakers previously introduced legislation aimed at halting private sales of Lake City ammunition, but it failed to reach a vote. This time, investigative reporting by ICIJ and the New York Times is drawing international attention, and different results are expected.

However, given the Republican-dominated structure of Congress and the political divisions surrounding the Second Amendment (the right to bear arms), passage of the bill is likely to face significant challenges. Gun-related legislation is one of the most intense areas of partisan conflict in the United States, with the Democratic Party's public health and safety logic directly clashing with the Republican Party's constitutional rights and national security logic.

This issue goes beyond a simple domestic gun control issue and touches on complex issues such as U.S.-Mexico relations, countering transnational criminal organizations, and the ethical responsibility of the defense industry. With cartel violence threatening Mexico's national security and impacting the U.S. border region, international pressure to control the flow of U.S. weapons and ammunition is likely to increase.

“We should not live in a world where weapons and ammunition sold by our government end up in the hands of violent criminals and devastate our communities,” said Rep. Robert Garcia. The paradoxical situation in which military ammunition produced with taxpayer money threatens its own citizens and citizens of neighboring countries calls for a fundamental reexamination of U.S. defense policy.
