This is a long-term contract for two specific National Stock Number (NSN) items, which require engineering source approval from the design control activity to maintain part quality. The acquisition is limited to approved sources or alternates that can qualify through specific government-approved procedures, as these sources retain essential data rights and manufacturing knowledge. To be eligible, offerors and their suppliers must have an approved US/Canada Joint Certification Program (JCP) certification and DLA approval to access export-controlled technical data. Approved sources and part numbers are listed as MAGPUL INDUSTRIES CORP. for both contract line items. Interested sources must complete and return the attached market survey documents by April 6, 2026.
