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. A multi-barreled chaingun firing 5mm ammunition at over 60,000 RPM. The 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. It's the favorite weapon of the Mariposa super mutants during the Unity's time. Another model with six barrels linked into pairs and used in combination with a cassette ammo box also exist.

CZ57 Avenger minigun


 Rockwell designed the CZ57 Avenger as the replacement for their aging CZ53 personal minigun. The Avenger's design improvements include improved gel-fin cooling and chromium plated barrel-bores. This gives it a greater range and lethality. Another rare model with rusty metallic plate and used in combination with a cassette ammo box also exists. 

Vindicator minigun


The German Rheinmetall AG company created the ultimate minigun. The Vindicator throws over 90,000 caseless shells per minute down its six carbon-polymer barrels. As the pinnacle of Teutonic engineering skill, it is the ultimate hand-held weapon. Another model with a new design, a display screen that show the remaining ammunition and chambered for much more common 7.62mm bullets also exist.

MEC Gauss minigun


The MEC Gauss minigun was designed by the Chinese. Rare for an automatic weapon it uses Gauss technology, multiple electromagnetic fields to propel over 90,000 rounds per minute to relativistic velocities.

Vault-Tec 9mm minigun


 An after war minigun designed by Vault-Tec in the Secret Vault. The Vault-Tec 9mm minigun has a lower rate of fire than a general minigun but chambered in 9mm, an uncommon high caliber for a minigun. It has five barrels and it used by the Attis army in Texas. 

CZ25 military minigun


A Rockwell CZ25 Military Minigun. A multi-barreled weapon capable of firing large quantities of ammo with minimal heal issues.

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 CZ-75 pistol or Skorpion submachine gun).
