The Federal Bureau of Investigation (FBI) is seeking information from qualified vendors regarding the procurement of 5.56 NATO/223 Remington ammunition through a Request for Information (RFI). The RFI aims to gather insights on various ammunition categories, including Service, Training Reduced-Lead, Frangible, and Suppressor-Safe Frangible, with specific requirements for compatibility with FBI carbines and performance standards such as low failure rates and resilience under extreme conditions. This initiative is crucial for enhancing the operational effectiveness and safety of FBI operations, as it will inform future Requests for Proposals (RFPs) tailored to the agency's ammunition needs. Interested parties should submit their capabilities by April 17, 2025, and can direct inquiries to Katelyn R. Haus at KRHAUS@fbi.gov.
