DLA Weapons Support is preparing a long-term contract for a list of National Stock Numbers (NSNs) and is seeking business concerns interested in manufacturing these items. The parts are subject to restrictions such as engineering source approval, limited data rights, or other noncompetitive conditions, meaning alternate sources must qualify through government-approved procedures. A market survey and spreadsheet must be completed and returned to the point of contact to indicate interest. The solicitation will be synopsized separately at a later time. The applicable NAICS code is 332510 with a business size standard of 750 employees.
