The M8A1 (called XM8 in early footage and game files) is a four-round burst assault rifle featured in Call of Duty: Black Ops II, Call of Duty: Strike Team, and Call of Duty: Heroes.

Call of Duty: Black Ops II Edit

Campaign Edit

"Fully automatic assault rifle. High rate of fire with moderate recoil."
— Campaign Description

Unlike its multiplayer and zombies counterpart, the M8A1 is fully-automatic by default in the campaign, though the Select Fire attachment makes it 4-round burst. It is part of the recommended loadout for "Odysseus", where it is equipped with a hybrid optic. It is also commonly used by friendly factions and by the Mercs in this mission.

Multiplayer Edit

"4 round burst assault rifle. Bursts can be fired in quick succession."
— Description

The M8A1 can kill with just three shots at close range, however, at long range, five shots are required to kill.

The iron sights are moderately clear and can be used effectively by experienced players, but to use the M8A1's ranged capabilities, an optical attachment, such as the EOTech Sight or the ACOG Scope is recommended.

Select Fire can turn the M8A1 into a fully-automatic assault rifle. Due to its high rate of fire and good damage, it can be effective in close range over the burst-fire, and at longer distances, the player may switch to burst-fire for higher accuracy.

The M8A1 has no headshot multipliers, so it is not recommended to aim at the head, unless deliberately completing weapon challenges, as it is a smaller target than the chest. The M8A1 also suffers from having its three shot kill range ending at 1.25 meters, meaning that at anything beyond point-blank range it requires four to five shots in order to kill an enemy. The four shot kill range, however, is very good, ending at 30 meters.

Overall, the M8A1 is a great weapon for medium to long-range combat; players can perform covering fire for teamates from a safe distance, making the M8A1 quite a defensive weapon.

Zombies Edit

"The M8A1 automatic rifle with a 5.56mm 32-round magazine could be...ugh, I could just say, 'It's fine.' I guess..."
Marlton Johnson in Green Run, when obtaining the M8A1 from the Mystery Box.

The M8A1 is available in Green Run, Nuketown Zombies, and Die Rise for 950 points from the Mystery Box. It retains its four-round burst fire mode from multiplayer. Double Tap Root Beer can be very useful with this gun, as its four-round bursts start off somewhat weak, making it difficult to kill zombies quickly. It can be very good for accumulating points in the right hands, and is suitable for shooting zombie hordes. Although the recoil is moderate, the recoil can actually be used to the players' advantage, as if the player aims at the chest, the final 2 bullets will usually hit the head, scoring headshot points, if not a headshot.

When Pack-a-Punched via the Pack-a-Punch Machine, it becomes the Micro Aerator. The Micro Aerator can perform exceptional headshot damage, as its four-round bursts can eliminate zombies with ease until as late as round 24, with Double Tap Root Beer. It also holds a large ammo capacity, making it one of the more worthwhile weapons to Pack-a-Punch. Also of note, its hip fire accuracy is increased dramatically, increasing its close quarters effectiveness. It is one of the weapons that is able to be Pack-a-Punched multiple times to cycle through attachments for 2000 points. Attachments include the Reflex Sight, EOTech sight, Target FinderMillimeter Scanner and the Grenade Launcher.

  • When Kryptek: Typhon Camouflage is applied, the M8A1 will act as an overlay, retaining the original colors but adding the scaly pattern over them, whereas with other weapons, the original colors are changed to black. It will also reflect with a red hue when light is shined on it. 
  • 'KHK M8A1 MK II' is written on the left side of the M8A1, as is 'KHK US GERMANY'. This is easily seen when moving forward while in the prone stance.
    • "5.56x45 MM NATO" can be seen on the magazine and on the left side of the gun.
  • If the Extended Clip is equipped, the magazine size will increase to 42. 42 is not divisible by 4, meaning that the player will only have a two round burst before the magazine is empty. This is also the case for the Micro Aerator in Zombies.
  • The Overkill wildcard image shows a soldier carrying a M8A1 and a MSMC.
  • One of the soldiers in muitlplayer menu image is using a M8A1.
  • The icon of Extended Clip is the magazine of M8A1.
  • The icon of Long Barrel is the M8A1's barrel, but in Black Ops II, Long Barrel isn't available for assault rifles.
