About this opportunity

Written by GovTribe AI · Jan 21, 2026

The Department of the Army Materiel Command Contracting Command Rock Island Arsenal is soliciting proposals for a second source supplier to produce 5.56mm, 7.62mm, and .50 caliber ammunition under RFP W519TC-25-R-0034. The contract spans five years with six ordering periods, with best estimated quantities of 75 million rounds of 5.56mm, 48 million rounds of 7.62mm, and 4.5 million rounds of .50 caliber ammunition per ordering period (capped at 15 million maximum for .50 caliber). Key requirements include obtaining finished components exclusively from U.S. or Canadian sources, demonstrating significant production capabilities, implementing supply chain risk management protocols, and meeting rigorous technical specifications and quality control standards. Evaluation will focus on technical capability, past performance, and small business participation, with proposals requiring comprehensive technical volumes including integrated master schedules, failure analysis reports, and evidence of production capability across multiple Department of Defense identification codes. The proposal submission deadline is February 17, 2026, and potential offerors were required to submit questions and comments using the provided template by December 12, 2025, with subsequent amendments issued on January 6 and January 16, 2026 to address industry inquiries and clarify requirements.

This solicitation carries no set-aside designation and involves no identified incumbent contractors in the available materials. While specific award values are not disclosed in the opportunity documents, the contract's five-year duration combined with the substantial quantity requirements—totaling millions of rounds across three caliber types—indicates a significant procurement commitment. The government has implemented a nitrocellulose pricing re-opener mechanism for ordering periods 1-5 to address commodity cost fluctuations, and will permit delivery of .50 caliber quantities exceeding 10 million rounds to extend up to two years after contract award to accommodate production capacity constraints. Place of performance details are specified through the Technical Data Packages and solicitation documents available via the Procurement Integrated Enterprise Environment (PIEE) website, though specific manufacturing locations must comply with the domestic sourcing requirements for finished components established in the RFP.
