Plunger assembly - NSN : 1015013406103

The Department of the Army, through Army Contracting Command-Detroit Arsenal, is soliciting offers for a Plunger Assembly (NSN 1015-01-340-6103) for the 105mm M119A1 Howitzer weapon system under solicitation W912CH-24-Q-0077. Qualified bidders must be registered in the System for Award Management (SAM) with a NAICS code of 332994 (Small Arms, Ordnance, and Ordnance Accessories Manufacturing) and must be certified under the United States/Canada Joint Certification Program to access the export-controlled technical data package. The contract will be awarded on a Firm Fixed Price basis using a lowest price technically acceptable evaluation approach. Critical requirements include submission of heavy phosphate coating procedures, engineering change proposals, requests for variance, and a First Article Test Report. The proposal due date is January 14, 2026, as established by Amendment 0001, which also reduced the First Article Test lead time from 240 to 60 days after contract award.

This procurement is designated as a 100% Small Business Set-Aside, restricting competition to qualified small businesses. The solicitation encompasses a base quantity of 21 units with an additional 21-unit option quantity, totaling an estimated 42 plunger assemblies. The delivery schedule specifies 150 days for the base quantity without First Article Testing or 240 days if FAT is required; however, the amendment reduced the FAT lead time to 60 days, effectively shortening overall delivery timelines. Place of performance is the United States. No incumbent contractor information or specific award value is disclosed in the solicitation documents, though the firm fixed-price nature and component-level specification suggest a competitively-priced supply contract reflective of current defense ordnance accessory manufacturing rates.
