This is an original 40mm M5 Armament Subsystem Chute Unit, part number 11014424, offered in new old stock condition. Designed for the M5 Armament Subsystem, this chute unit served as a vital component in the ammunition handling and ejection system of the 40mm M5 automatic grenade launcher, primarily installed on UH-1B, UH-1C, and UH-1M “Huey” helicopters during the Vietnam War.

The M5 Subsystem was an early attempt to enhance helicopter gunship capabilities with a belt-fed 40mm weapon platform. Mounted in a forward-firing, fixed configuration, the M5 utilized the M75 grenade launcher, later replaced by the improved M8 with the M129 launcher. The Chute Unit played a crucial role in ejecting spent links and cases after firing. Its function ensured smooth ejection during sustained combat operations in high-vibration, high-stress environments.

This particular unit is exhibiting light wear consistent with long-term storage. It’s an excellent addition to restoration projects, aviation museums, or collectors seeking authentic Vietnam-era helicopter ordnance components.
