Abstract: A clamping mechanism corrects a design flaw in the NSN 1005-01-431-8324 adapter assembly without modifying it. The fine details of military regulations have encouraged the design flaw's persistence by limiting and preventing actions for correcting or modifying the NSN 1005-01-431-8324 adapter assembly. The clamping mechanism can be fielded without violating any regulations and thereby without necessitating the very expensive and time consuming acceptance procedures that would be required of other solutions. The clamping mechanism addresses the design flaw while simultaneously remaining within the regulatory regime.
