Description
Sprocket for the Ammunition Booster on M6, XM16, and M16 A.S.S.
The Sprocket for the Ammunition Booster on M6, XM16, and M16 A.S.S., identified by P/N 11687063 and package FSN 1005-070-0952, was used in the ammunition-feed equipment of U.S. Army helicopter armament subsystems. Its later federal catalog identification is NSN 3020-00-070-0952.
The sprocket was a component of the booster that moved linked 7.62mm ammunition toward the subsystem's M60CA1 machine guns. It is not a component of the M16 rifle.
Historical Significance
The M6 was a quad-machine-gun armament subsystem developed for the UH-1B helicopter. It used electrically directed left- and right-hand mounts carrying four 7.62mm M60CA1 machine guns, together with ammunition boxes and feed chutes.
The XM16 and standardized M16 armament subsystems combined the M6 machine-gun installation with 2.75-inch rocket launchers. The Sprocket for the Ammunition Booster on M6, XM16, and M16 A.S.S. belonged to the linked-ammunition feed side of these systems, not the rocket-launcher equipment.
M6, XM16, and M16 Armament-Subsystem Relationship
In this designation, A.S.S. refers to the helicopter armament subsystem. The M6 provided the four-gun installation, while the XM16 and M16 expanded that arrangement by adding paired rocket launchers on the universal mounts.
Because the XM16 and M16 retained the M6 machine-gun equipment, ammunition-feed components such as this booster sprocket were associated with all three subsystem designations.
What This Item Is and Does
The Sprocket for the Ammunition Booster on M6, XM16, and M16 A.S.S. was the rotating belt-engagement component within the ammunition booster. Driven by the booster mechanism, its shaped teeth engaged the linked cartridges and assisted their movement from the ammunition boxes through the feed chutes toward the machine guns.
Federal catalog data describes P/N 11687063 as an assembly consisting of one sprocket wheel, P/N 11687062, and two discs, P/N 11699386. The photographed component shows those two broad end discs around the sprocket body.
