Olin Winchester LLC

Olin Winchester LLC, doing business as Olin Chlor Alkali Products, manufactures small caliber ammunition and shotshells at its East Alton, Illinois facility and supplies them to federal law enforcement, homeland security, and defense agencies as a prime contractor on full-and-open procurements with no set-aside designations. The company operates as a limited liability partnership structured as a for-profit organization and competes across the federal ammunition market without reliance on socioeconomic set-asides.

Olin Winchester's federal footprint centers on specialized ammunition products: 9mm Luger and 9mm frangible rounds, .223 Remington and 5.56mm NATO rifle ammunition, .40 S&W and .45 ACP handgun rounds, 12 gauge shotshells in standard and reduced-hazard configurations, and Readily Identifiable Training Ammunition (RITA) variants. Recent representative prime work includes a $2.254 million firm fixed-price delivery order from the Air Force Sustainment Center (March 2026) for 9mm frangible ammunition through April 2028, a $6.578 million delivery order from the same customer (September 2024) for 9mm frangible ammunition through January 2027, a $4.924 million delivery order from the Air Force (September 2025) for 9mm frangible ammunition through November 2027, and a $1.714 million delivery order from the Federal Law Enforcement Training Center (January 2026) for 4 million rounds of 9mm reduced hazard training ammunition.

Customer concentration by dollar value is dominated by the Department of the Army Acquisition Support Center PEO Ammunition (Program Executive Office Ammunition), which anchors 78 percent of the combined potential value across the award portfolio with 21 awards totaling $876.3 million. This concentration reflects the Army's substantial ammunition procurement demand and Olin Winchester's position as a qualified supplier on Army contracts. The Federal Law Enforcement Training Center (FLETC), a civilian Department of Homeland Security entity, ranks second with 90 awards carrying $96.4 million combined potential value and represents the highest award count among customers. Immigration and Customs Enforcement (31 awards, $66.3 million) and the Federal Bureau of Investigation (17 awards, $24.7 million) complete the top four by dollar value. By award count, the concentration is more distributed: the National Park Service Intermountain Region leads with 95 awards but carries only $343 thousand potential value, reflecting high-volume small orders across NPS regional offices, while FLETC (90 awards) and NPS Southeast Region (82 awards) and Northeast Region (75 awards) round out the top five. This divergence signals that Olin Winchester supplies mission-critical recurring ammunition needs across numerous small NPS locations while anchoring major contract vehicles with the Army and DHS.

Olin Winchester holds multiple indefinite delivery contracts and blanket purchase agreements serving as primary procurement vehicles. The single-award Indefinite Delivery Contract with Immigration and Customs Enforcement (IDC 70LGLY25DGLB00001, awarded May 2025, ceiling $15.273 million, through May 2030) provides 9mm Readily Identifiable Training Ammunition to support ICE's Office of Firearms and Tactical Programs. The multiple-award Commercial Lead Training Ammunition II Generation (CLTA II) IDC with FLETC (awarded March 2025, ceiling $8.75 million, through February 2027) covers various calibers including 9mm, .223 Remington, 5.56mm NATO, and 12 gauge training rounds; this vehicle has generated 110 task orders with $4.9 million combined potential value. A single-award Blanket Purchase Agreement with the U.S. Fish and Wildlife Service (awarded February 2026, ceiling $1.5 million, through February 2031) covers small arms ammunition for law enforcement operations. The FBI multiple-award IDC (awarded September 2023, ceiling $2 million, through January 2026) procures 5.56mm NATO and .223 Remington reduced-lead training ammunition. A fourth active IDC managed by FLETC (70LGLY21DGLB00002) has generated 91 task orders worth $33.2 million combined potential value. The top parent vehicle, the Commercial Lead Training Ammunition contract, supports ammunition procurement for federal law enforcement training across civilian agencies.

Activity has declined year over year from 184 awards in 2022 to 52 awards through October 2026, representing a 72 percent drop over four years. This trajectory signals either market saturation following post-pandemic ammunition demand peaks or increased consolidation of procurement through larger standing orders (particularly the Army IDCs) rather than numerous small delivery orders. Recompete exposure in the next twenty-four months amounts to 26 awards with combined potential value $22.2 million—modest relative to the $1.37 billion total portfolio, but concentrated in active training ammunition vehicles that will require renewal.

Olin Winchester operates as a prime contractor on 99 percent of awards (821 of 831), with minimal subcontract activity. The two sub-award entries on record are ordnance components (M789 HEDP and M799 TP cartridges) supplied to General Dynamics Ordnance & Tactical Systems in October 2025, suggesting rare downstream support rather than a strategic subcontracting posture.

The vendor competes across 100 distinct customer agencies spanning civilian law enforcement, correctional, homeland security, and defense customers. The National Park Service alone accounts for 291 awards concentrated across regional offices (Intermountain, Southeast, Northeast, Pacific West regions), driven by routine ammunition replenishment for park ranger law enforcement operations. The breadth of customer relationships—from the DEA to the Transportation Security Administration to the Naval Sea Systems Command to the Secret Service—positions Olin Winchester as a de facto sole supplier for specialized training and operational ammunition across federal civilian and military entities, sustained through full-and-open competitive procurements and recurring delivery order demand against established IDIQ vehicles rather than set-aside targeting.
