The Government seeks one unit of NSN 7R-1560-015302403-GF under TDP version 001, delivered FOB origin, with early and incremental deliveries accepted. Contractual documents are considered issued when mailed, faxed, or sent electronically, and the contractor’s acceptance of the proposal constitutes bilateral agreement to that issuance method. The action is intended for sole-source solicitation and negotiation under FAR 6.302-1; responsible sources may identify interest and capability or submit proposals, but this notice is not a request for competitive proposals. The Government is not using FAR Part 12 commercial-item policies, though interested parties may identify commercial-item interest and capability to the contracting officer.
