Components of M134 Minigun are the Rotor Assembly, Six Bolts Assemblies, Six Removable Bolt Tracks, Gun housing Assembly, Rear Gun Support, Six Barrels, Barrel Clamp Assembly, Safing Sector Housing Cove, Two Quick Release Pins.As the rotor turns within the stationary housing cover, the bolt assembly rollers follow the main cam path of the housing cover, causing the bolt assemblies to move along the accommodating tracks. Each barrel is mounted in the barrel clamp assembly, in a fixed position, in alignment with a bolt assembly.
Feeder/Delinker
Its function is to delink ammunition, then feed it to the gun.
Spade Grip
Gun Control Unit
When the GUC trigger is released, power is removed form the weapon. The Clutch disengaged and the flow of ammunition to the gun is interrupted. After the Clutch disengages the "Time Relay Circuit" continues to supply power to the gun motor long enough to ensure that all remaining live rounds have been fired. There is no live rounds left in the gun.
Clutch
Its function is to control the engagement/disengagement of the Delinker in time with the gun.
The clutch also ensures the weapon is clear of live ammunition each time the trigger is released.
When the gun trigger is pressed, power is delivered to the gun and to the clutch. The clutch then
engages the delinker drive gear, causing the delinker to feed ammunition to the gun.
When the trigger is released, power is first removed from the clutch, which disengages the delinker, stopping the flow of ammunition. A time delay relay continues to turn the gun barrels until the six remaining rounds are fired. The clutch is always free of live ammunition. Since, there is no life ammunition in the chambers after firing, the clutch is not susceptible to accidental discharges resulting from " cooks-off ".
DC Gun Drive Motor
M134 fires at a rate of 3000 shots per minute.
28 Volt DC Drive Unit Assembly
Gear Head
The Gear Head that is installed on the gun drive motor determines the guns rate of fire.
3000 shots per minute (spm) / 4000 shots per minute
Safing Top Cover
This unit gives users a mechanical safety that functions as a cycling sector. That means the gunner can mechanically safe the weapon without disassembling it.
To open and safe the weapon, press the latch and lift. Once open the spring-loaded latch locks the Safing Sector in the open position. it is nos possible to cycle live ammunition through without firing the weapon. This allows the operator to clear the gun of remaining cartridges or check the function of the weapon in the shortest amount of time possible.
Rotor
At the center of M134 is the Rotor. When the weapon is triggered the main drive motor turns the
drive gear on the front of the rotor. This in turn drives the six gun bolts through the firing sequence. The blots follow the cam path around the weapon housing while moving linearly along the rotor bolt track. From chambering and firing, to extraction and ejection each revolution of the rotor results in six rounds being fired.
The rotor is the gun. It is the part of the weapon that must be approved by congress to be
purchased.
Top Cover
The user has only to release two spring loaded latches and pivot the Top Cover/Safing Sector
to the safe position. No loose parts, no tools are required.
Gun Housing
The main Gun Housing provides mounting surfaces for the Drive Motor, Safing Top Cover,
Feeder/Delinker, and Spade Grips.Additionally, the Gun Housing contains the Rotor and Clutch.

Barrel
Barrel Clamp and Flash Suppressor
1.Holding the barrel group in alignment 2.Reduce flash emissions by enabling the mixture of air
with unburned powder.
Increase flash suppression and decrease muzzle debris making it better suited for use with
Night Vision Goggles.
Blot Assembly
The Gun Bolt Set is compromised of six Gun Bolts.
Firing pins found in GE bolts have blunt tips. Blunt tips can puncture the primer of a cartridge
during the firing sequence. When this happens a portion of the hot gas is vented passed the
firing pin and through the bolt. This has two effects.
The first is to cause the firing pin to compress the firing pin spring rearward against the firing pin
retention pin. If this happens enough times the firing pin spring will lose temper, which leads to light firing pin strikes on primers. These 'light strikes' may contain insufficient energy to fire the cartridge.
The second effect of gas venting is to 'etch' the tip of the firing pin. The more the firing pin tip is
damaged the more likely it is to puncture larger holes in the primer. At a certain point enough gas is vented into the bolt body that the bolt head retention pin may actually be sheared into three pieces, leading to catastrophic bolt failure.
?????? I still confuse with the above problems. ??????
The firing pin tip is rounded, not blunt, to avoid primer puncture. In firing tests totaling well over one million rounds, Dillon Bolts did not puncture a single primer.
Cable Harness
4000 Round Magazines and Ammunition Feed System
Used in helicopter installations, including Black Hawk, Huey, Chinook.
Large capacity magazines have been a traditional source of weapon malfunctions. Each magazine is divided into two compartments creating twin ammunition bays. Each bay is divided with a single half-height baffle or, one half-height baffle and two small sub baffles. These baffles serve to control the ammunition, preventing the tucking and the cartridge interlocking that is the cause of the most magazine jams.
Booster Assembly
Booster Assembly provides the extra push necessary fro moving ammunition over longer distances. It mounted directly on the top of the magazine lid and powers ammunition before it enters the feed chute.
Narrow Profile Booster emphasizes the economy of space.

Round Repositioner
All ammunition must travel to the battlefield. that travel is hard on linked ammunition. Vibration
caused bu continuous shaking of rough roads or mishandling can cause belted rounds to shift in
the link. They are a common source of weapon malfunction.
When a round shifts, becoming mislinked, it moves out of alignment in relation to the other rounds in the belt. Consequently, that belt becomes too wide to enter either a feed chute, if one is being used, or the feed port on the weapon itself. The result is a feed stoppage, the cause of which usually going undetermined.
Like all belt-fed weapons, the M134's feed system is sensitive to mislinked ammunition. To combat mislinked rounds, a Round Repositioner is installed at the magazine's exit. The inside of the Round Repositioner is shaped like a funnel allowing it to reposition any round not properly linked prior to entering the feed chute.
Gun Mount/Black Hawk
No doubt the Gatling Machine Gun has been the legendary machine gun. Look back the history,
from the birth (during Civil War), obsolete (due to Maxim Machine Gun was invent in 1884),
and then came alive (Aviation) that brought the Gatling Machine Gun to the modern warfare.
What an elusive vicissitude !!
