The GAU-5A/A 5.56 mm carbine.

The GAU-5A/A is a 5.56 mm carbine that remains unused by any faction in ArmA 3. It was added with the release of the S.O.G. Prairie Fire Creator DLC.

Overview[]

This section is a stub. You can help Armed Assault Wiki by expanding it.

The GAU-5A/A is an XM177 carbine designed specifically for use by the U.S. Air Force's aircrews as a self-defence weapon.

It primarily feeds from the same 18-round magazines used by the XM177/M16A1, and is also (optionally) capable of loading newer 28-round curved magazines as well as 36-round dual magazines. The GAU-5A/A has a muzzle velocity of 838 m/s[CfgWp 8] and can attain a fire rate of up to 600 rounds per minute on semi-auto[CfgWp 9][Formula 1] or 800 RPM on full auto.[CfgWp 10][Formula 2]

GAU-5A/As cannot be fitted with suppressors or bayonets. However, they do allow the user to mount riflescopes, first generation night vision sights, or an experimental unmagnified sight onto the carryhandle.[CfgWp 11] Lastly, the user also retains the ability to mount an M16-type bipod onto the barrel for added stability during fully automatic fire.[CfgWp 12]

Ironsights[]

Arma3-sogpfgau5aa-ironsight-overview

Ironsights on the GAU-5A/A's carryhandle can be manually zeroed, though only two range settings are actually available (300 metres or 400 metres).[CfgWp 13] By default, it is set to a zeroing of 300 metres.[CfgWp 14]

If an optical sight that allows for manual zeroing greater than 400 metres is fitted, then the GAU-5A/A can be zeroed up to a maximum of 1,000 metres.[CfgWp 15] It should be noted that this also applies to zeroing under 300 metres.[note 1]

Melee[]

Melee attacks with the GAU-5A/A will involve striking targets with a buttstroke. Melee attacks can inflict a maximum of up to 7 points of damage to the target if the buttstroke lands successfully.[CfgAm 1]

It should be noted that melee attacks will drain 3.96 points of stamina[Formula 3] whenever a buttstroke is performed.[SCR 1]

Ammunition[]

NOTE: The GAU-5A/A is capable of loading the same magazines utilised by non-S.O.G. 5.56 mm-chambered weapons. To minimise clutter, they are deliberately excluded from this section.

Ammo parameter 5.56 mm (Ball/Tracer)
Base damage value 8[CfgAm 2]
Aerodynamic friction -0.001425[CfgAm 3]
Muzzle velocity (m/s) 900
[CfgMa 4][note 2]
Actual: 838
[CfgWp 8][note 3]
Expected velocity (m/s) 936
[CfgAm 4][note 4]
Penetration depth (mm) 13.5
[CfgAm 5][Formula 4]
Actual: 12.57
[Formula 5][note 5]
Deflection angle (degrees) 20°[CfgAm 6]

The GAU-5A/A can load up to six types of magazines:[CfgWp 16]

  • Two of these magazines are the standard 18-round box magazines.[note 6] They have a weight of 7 "mass" units.[CfgMa 5]
  • Two magazines have a capacity of twenty-eight rounds.[note 7] These magazines have a weight of 9 "mass" units.[CfgMa 6]
  • The remaining two magazines have a capacity of thirty-six rounds (they are simply two 18-round box magazines that have been taped together).[note 8] These magazines have a weight of 14 "mass" units.[CfgMa 7]

These magazines are compatible with the M16A1 assault rifle and XM177 carbines but cannot be shared with the M63A modular rifle:

It should be noted that magazines from other Creator DLCs that share access to the same pool of magazines (Classname: STANAG_556x45) can also be loaded into the GAU-5A/A. However, those Creator DLCs must be loaded simultaneously alongside S.O.G. Prairie Fire in order for them to appear as selectable options in the Virtual Arsenal.


Trivia[]

  • The GAU-5A/A was not available as part of S.O.G.'s launch content and was only added after the release of Update 1.2.[1]

Formulae

  1. ↑ 60 / reloadTime = 60 / 0.1
  2. ↑ 60 / reloadTime = 60 / 0.075
  3. ↑ (mass * 0.04) * dexterity = (60 * 0.04) * 1.65
  4. ↑ Magazine's initSpeed * Ammo's caliber * 15 / 1000 = 900 * 1 * 15 / 1000
  5. ↑ Weapon's initSpeed * Ammo's caliber * 15 / 1000 = 838 * 1 * 15 / 1000

Notes[]

  1. ↑ Removing the optic will automatically reset the zeroing to either a minimum of 300 metres (if zeroing was set to under 200 metres or less) or a maximum of 400 metres (if the optic was utilising a zeroing setting of 500 or more metres).
  2. ↑ Only applies to the magazine itself. Even though the magazine has an initSpeed of 900 m/s, the GAU-5A/A's weapon class has its own initSpeed value defined (838 m/s) which always takes precedence over the magazine's initSpeed since the weapon's initSpeed value is not defined as a coefficient.
  3. ↑ This is the GAU-5A/A's actual muzzle velocity. The weapon class initSpeed value (838 m/s) takes precedence over the magazine initSpeed value (900 m/s).
  4. ↑ Damage will be reduced if the projectile's velocity drops below this value.
  5. ↑ This is the actual penetration depth of the GAU-5A/A's 5.56 mm ammunition. The weapon class initSpeed value (838 m/s) takes precedence over the magazine initSpeed value (900 m/s), affecting its penetration formula as a result.
  6. ↑ This magazine technically has a capacity of twenty rounds (and is even named as such) but is actually configured to store only eighteen rounds.
  7. ↑ This magazine technically has a capacity of thirty rounds (and is even named as such) but is actually configured to store only twenty-eight rounds.
  8. ↑ This magazine technically has a capacity of forty rounds (and is even named as such) but is actually configured to store only thirty-six rounds.
