A machine gun mount is provided for mounting a machine gun in a movable
support arm of a helicopter. The mount includes a gun cradle which is
detachably connected to the gun and a pintle one end of which is adapted
to pivotably mount the pintle, and thus the mount, on the movable support
arm. This enables pivoting movement of the gun in a horizontal plane. The
pintle is pivotably connected at the opposite end to the cradle so as to
permit the cradle, and thus the gun, to be rotated in a vertical plane
through 90 degrees between operative and stowed positions. A locking
mechanism locks the cradle in the stowed position. A magazine is attached
to one side of the cradle while a spent case and link frame and
associated catch bag are attached to the opposite side. The magazine
includes an inwardly projecting portion disposed below the cradle.
