Description
7.62mm M134 Ejection Chute for M28A1 Armament Subsystem, P/N 11690407
The 7.62mm M134 Ejection Chute for M28A1 Armament Subsystem, P/N 11690407 is a U.S. Army helicopter-armament component made for the right-hand M134 Minigun position in the M28A1 chin turret used on the Bell AH-1G Cobra.
Cataloged as Chute, Ejection, this identified component carries NSN 1005-00-127-2982 and alternate part number 717025-301.
Historical Significance
The M28A1 was a defining armament subsystem of the Vietnam-era AH-1G Cobra. Mounted beneath the helicopter's nose, the turret combined the 7.62mm M134 Minigun and the M129 40mm grenade launcher in a compact, trainable installation.
This chute belongs specifically to the M134 side of that system. It is not the separate chute used with the M129 grenade launcher.
M28A1 Right-Hand M134 Installation
Army parts documentation identifies P/N 11690407 as Figure 2, Item 6 in the right-hand 7.62mm M134 installation of the M28A1 armament subsystem. The alternate number 717025-301 is associated with the same chute.
The available records identify its role only as an ejection chute and do not distinguish whether it handled cartridge cases, links, or both.
What This Item Is and Does
This is a formed chute assembly installed with the right-hand M134 Minigun in the M28A1 chin-turret system. During operation, it directed discharged material away from the gun installation.
It is an individual subsystem component, not a complete weapon, feed system, or turret assembly.

Why This Item Matters
Few surviving parts are as closely tied to the working layout of the AH-1G Cobra's distinctive nose turret. The documented part and stock numbers make this chute a useful reference component for interpreting the M28A1 and its right-hand M134 installation.
Its clear connection to the Cobra's Vietnam-era armament system gives it particular value for museum displays, technical study, restoration reference, and advanced military-aviation collections.
