A powered anti-aircraft mount carrying four heavy .50 caliber machine guns in a boxed cradle, their long perforated barrel jackets angled skyward. Linked ammunition feeds run from stacked ammo cans on each side into the guns, with a small gunner's seat at the rear.

The whole assembly sits on a traversing pedestal atop a bolted, latticework base, ready to sweep the sky. Barrels, feed chutes, ammo boxes, and the elevation gearing are crisply detailed.

A hard-hitting emplaced weapon for Vietnam and mid-century wargame tables, firebase and convoy-defense dioramas, and static defensive positions.
