What caliber is the GAU-21?

Explanation:
Caliber determines the bore size and the ammunition a gun fires. The GAU-21 is a .50 caliber machine gun, meaning it uses rounds with a 0.50 inch (12.7 mm) bore. That’s why the 50 Cal option is the correct pick. The other sizes correspond to different autocannons (25 mm, 20 mm, 30 mm) and do not apply to this Gatling-type gun.
