Description
20mm M39 Hand Charger Adapter. P/N 8415323
The 20mm M39 Hand Charger Adapter, identified by P/N 8415323 and NSN 1005-00-525-7375, is a U.S. military aircraft-armament support component associated with the M39 20mm automatic gun. It provides a mechanical interface for the gun's hand-charging equipment.
The adapter belongs to the support hardware used to move the M39 gun mechanism by hand during ground handling and maintenance. It is a separate component of the charging system, not a complete automatic gun.
Historical Significance
The M39 gun family was part of U.S. Air Force fighter armament during the early Cold War jet era. A 1956 Air Force manual identifies the earlier T160 designation as the standard-issue M39 and describes the parent gun as gas-operated, belt-fed, and electrically fired.
The M39 also equipped aircraft such as the North American F-100F Super Sabre, which carried two M-39 20mm cannons. Small support components such as this hand charger adapter represent the maintenance hardware that accompanied those larger aircraft weapon systems.
What This Item Is and Does
The 20mm M39 Hand Charger Adapter provides the connection used to apply manual movement to the M39 charging mechanism. Hand charging allowed armorers and maintenance personnel to cycle the mechanism without relying on the gun's normal firing action.
Its role is limited to the charging interface. The adapter does not perform the firing, feeding, or ammunition-handling functions of the complete M39 gun system.
