Description
Add a specialized piece of Vietnam War-era helicopter armament hardware to your collection with this Output Shoulder Shaft for the M6 Armament Subsystem, identified by Part Number 11699479 and supplied FSN 1005-922-8016. This is a military-surplus component associated with the M6 / XM6E3 helicopter armament subsystem, a quad 7.62mm machine gun system used on UH-1B-series Huey helicopters.
Historical Significance
The M6 Armament Subsystem was part of the early U.S. Army helicopter gunship development period. Army technical manual records identify TM 9-1005-243-12 as covering the Armament Subsystem, Helicopter, 7.62mm Machine Gun, Quad, M6 (XM6E3) for UH-1B helicopters.
The M6 system belonged to the armed Huey era, when the Army was turning utility helicopters into escort and fire-support platforms. Small Arms Review notes that HU-1B aircraft, soon redesignated UH-1B, were delivered to Vietnam in December 1962 with XM6E3 armament subsystems, and that the M6 series used 7.62mm M60C machine guns fired remotely by solenoid.
That history gives this shaft strong collector value. It represents the mechanical support hardware behind one of the early standardized helicopter machine gun systems used during the Vietnam War.
The M6 Armament Subsystem Connection
The M6 / XM6E3 was a quad 7.62mm M60C machine gun helicopter armament subsystem associated with the UH-1B and UH-1C platform family. Army aviation gunnery references identify the M6 as a quad 7.62mm M60C machine gun system for UH-1B/C helicopters, with the XM6E3 configuration becoming the standard M6 system.
This Output Shoulder Shaft is best understood as a mechanical shaft component within that broader armament subsystem support family. It is not a complete weapon, mount, aircraft assembly, or firing system. It is a part-numbered hardware component connected to the M6 subsystem parts ecosystem.

Why This Part Matters
The M6 Armament Subsystem represents an important step in the development of armed helicopters. It helped move U.S. Army aviation from improvised helicopter weapons toward more standardized gunship armament packages.
This shaft helps preserve the support side of that system. Complete Huey gunships and M60C machine guns receive most of the attention, but the armament subsystem depended on many individual shafts, brackets, links, stops, mounts, drive components, and fasteners to function as a complete installation.
For collectors, this is a traceable part-numbered component tied to the Vietnam War helicopter armament story. It pairs well with M6 subsystem references, UH-1 Huey displays, M60C aircraft machine gun documentation, Vietnam War aviation collections, and U.S. Army aviation ordnance manuals.
