Minigun

A minigun is a multi-barrel machine gun with a high rate of fire, employing Gatling-style rotating barrels. It was a standard military weapon before the Great War, with Rockwell's CZ series being the most popular choice in the United States of America.

It is widely used by many factions such as the super mutants, Brotherhood of Steel and the Enclave, due to its extraordinary firepower at close range.

CZ53 personal minigun


 A Rockwell CZ53 personal minigun firing 5mm ammunition at over 60,000 RPM with an ammo capacity of 120x 5mm round. The CZ53 personal minigun makes up for the small 5mm round by sending a hail of bullets toward its target. Its sheer size, coupled with its trademark sound, is enough to send anyone in its path running for cover. It's a great weapon for suppressing fire, letting others flank the unsuspecting enemy. When the Great War struck, it was already an aging design and was slowly being replaced by the more advanced CZ57 Avenger minigun. Later model of CZ53 have six barrels linked into pairs, four barrels in the top and two in the bottom, a cage underneath to put the ammo box containing 240x 5mm round, and used in combination with a backpack. The first model was the favorite weapon of the Mariposa super mutants during the Unity's time.

Behind the scenes

 * The Avenger might be named after the GAU-8 Avenger 30mm Gatling-type rotary cannon mounted on the A-10 Thunderbolt II.
 * The CZ designation could possibly be a reference to the real-world weapon manufacturer, Česká zbrojovka (famous for the CZ-75 pistol and Skorpion submachine gun).
