Warren Introduces Bill to Block Civilian Sales of Military-Grade Ammunition From Army Plant

The bill seeks to close a contractor loophole that lets taxpayer-funded Lake City ammunition flow into civilian channels.

Overview

  • Senator Elizabeth Warren unveiled the Stop Militarizing Our Streets Act with Senator Andy Kim and Representatives Robert Garcia and Jamie Raskin as co-sponsors.
  • The measure would bar Pentagon contractors from selling military-grade assault weapons and ammunition to civilians and require sales only to dealers that meet minimum safety practices such as customer screening and low crime-gun trace rates.
  • The legislation targets the Army-owned Lake City Army Ammunition Plant in Missouri, which Olin Winchester operates under a contract that allows unsold military production to be sold on the commercial market.
  • Warren cited tracing of high-powered .50-caliber cartridges seized by Mexican authorities from cartels to the Lake City plant, and Mexican officials have reported that a large share of seized .50-caliber rounds originated there via U.S. gun shops.
  • A 2023 New York Times investigation linked Lake City AR-15 ammunition to at least a dozen U.S. mass shootings since 2012, and Olin/Winchester did not respond to requests for comment on the new proposal.
