Justification for Sole Source

This document is a Justification for Sole Source (J&A) supporting a procurement valued between $15,000 and $350,000 under Federal Acquisition Regulation (FAR) 13.106-1(b).

The procurement concerns honing stones from Barnes-Division of Nagel Precision, Inc., a sole source manufacturer. Two specific document numbers are referenced: DOC# 60853805 (Qty: 660 EA, Honing Stones, PIN: N1.M6002.3808) and DOC# 60853806 (Qty: 110 EA, Honing Stones, PIN: N1.M6002.6479). The justification establishes that these stone assemblies from Barnes-Division of Nagel Precision, Inc. are manufactured to specific standards meeting shaft sleeve material, stock removal, and desired surface finish requirements. The assemblies are pre-determined in size to fit exactly into Barnes hone tool assembly stone holders currently in use in Shop 31's Shafting section. The justification confirms that the requested material represents the Government's minimum requirements, that no substitutes are available, and that the procurement is for direct replacement parts and components for existing branded equipment. The sole source buy is in preparation for an upcoming shafting carrier overhaul to prevent work stoppages. The document was signed on 3/26/2026 by the Shop 31 Production Shop Planner and contracting officer Tricia Kathryn Wintersteen for DLA Weapons Support Puget Sound.
