A

Fire only in self defense or in response to formal order

27
Q

Barrel assembly

A

Comprises barrel and barrel extension assembly

28
Q

Receiver assembly

A

Support, protect, and house various assemblies

29
Q

Belt holding pawls and feed tray

A

Contribute to the correct feeding of the ammunition belt

30
Q

Link chute assembly

A

guides the used links out of the GAU

31
Q

Breech lock cam

A

Guides the breech lock

32
Q

Extractor switch

A

Guides the front end of the extractor/ ejector assembly

33
Q

Rear bracket sliding blocks assembly

A

Guides the aft portion of the weapon into the cradle assembly for mounting

34
Q

Front sliding shoes assembly

A

Guides the fore portion of the weapon into the cradle assembly for mounting

35
Q

Breech lock depressors

A

Force the breech lock down and off the breech lock cam, unlocking it from the bolt

36
Q

Barrel jacket and flash suppressor assembly

A

Protects the barrel and minimize muzzle flash

37
Q

Trunnion adapter

A

Secured the barrel jacket and flash hider

38
Q

Manual cocking assembly

A

Pulls the bolt assembly to the rear of the receiver assembly into the cocked position

39
Q

Bolt latch assembly

A

Holds back the bolt assembly on the open position. When fired the bolt latch is released by the bolt latch pawl

40
Q

When in FIRE

A

The firing cam is in the outward position, the sear slide is forced down and moved into the sear forcing the firing pin to extend

41
Q

Bolt assembly

A

Controls feeding, extracting, and ejecting operations, as well as operation of the firing pin

42
Q

Barrel buffer assembly

A

Absorbs recoil energy of the barrel assembly

43
Q

Feed cover assembly

A

Feed the ammunition belt from either side of the receiver assembly

44
Q

Backplate assembly

A

Used to stop the bolt assembly at the end of its rearward movement and to absorb its remaining recoil energy

45
Q

Backplate assembly

A

Used to stop the boat assembly at the end of its rear word, movement and to absorb it’s remaining recoil energy

46
Q

Auxiliary spring return assembly

A

Assist the rod assembly when pushing the bolt assembly toward the front position to ensure there’s enough force to pull the ammunition belt correctly into the gun

47
Q

Trigger assembly

A

Used to control the operation of the bolt latch to correctly hold back the bolt assembly at the rear clocked position and to release it

48
Q

Counter recoil phase

A

The beginning of the cycle of operation. It is initiated by depressing the trigger assembly, which lifts the boat latch and allows the compress rod and spring assembly to expand and send the bolt forward to the battery position. The compressed barrel buffer assembly, also expands and sends the barrel and barrel extension forward into the battery position.

49
Q

Recoil phase

A

Initiated by rapidly expanding gases generated as a bullet is being fired. These rapidly expanded gases, drive the barrel, extension, assembly and bolts to the rare of the weapon.
