The M27, referred to within game files as the HK416, is an assault rifle featured in Call of Duty: Black Ops II and can be used in Call of Duty: Black Ops III using console commands. The M27 is also seen in the intro cutscene for the zombies map Classified in Call of Duty: Black Ops 4.

Call of Duty: Black Ops II

"Fully automatic assault rifle. Reduced recoil provides higher accuracy."
Create-A-Class Description.


The M27 is an assault rifle that is particularly common in the campaign. It is the third most common assault rifle used by J-SOC and the Navy SEALS behind the SCAR-H and the M8A1. Some Mercs are also seen using it in the mission "Odysseus". The M27 is the primary weapon in the recommended loadout for the mission "Celerium". Javier Salazar and Mike Harper use it in the missions "Karma" and "Odysseus".


The M27 is the fifth weapon in the assault rifle category, and is unlocked at Level 31.

The M27 is very accurate; featuring a very low recoil pattern, but relatively low damage per shot, requiring four shots to kill out to medium range, or three if one is a headshot. It can take up to five shots at greater distances, or four if one is a headshot. Its rate of fire is average at 750 rounds per minute, on par with the MSMC and PDW-57, and its reload time is 2.03 seconds and its magazine capacity is 30 rounds respectively. These balanced traits make the M27 a fairly forgiving weapon at all ranges, as the moderate rate of fire and adequate reload speed allows the player to miss a few shots without significant consequences. At longer ranges however, it will be outclassed by burst-fire and semi automatic weapons such as the SWAT-556 and FAL OSW. Furthermore, the M27's low damage makes it inferior in close range engagements to weapons with a faster rate of fire, such as the Type 25. However, its 4-shot kill range extends to a very long distance, as it'll still deal 33 damage out to around 39 meters to compensate for its low damage in close-quarters. This long range makes the use of a Suppressor have a relatively low downside on the range, while giving an extreme stealth advantage to the user.

The primary advantage of the M27 is that it has very low recoil. This is the redeeming factor of the M27 and should not be underestimated. It is very easy to control, even at long range, making the M27 a very potent weapon on larger maps where jumpy recoil may hamper other assault rifles. When paired with a Suppressor, the M27 can effectively be used to eliminate players with Sniper Rifles and Light Machine Guns watching over objectives or long sightlines before they notice the threat.

The relatively clear iron sights reduce the need for an optical attachment, though the added precision of a Reflex Sight can aid in hitting distant opponents. The Target Finder can also prove effective in larger, more open maps like Carrier or Turbine. Alternatively, the combination of a Suppressor and Laser Sight can be an excellent choice for players hoping to tilt the odds in their favor by surprising their opponents and improving their reactivity.

Overall, the M27 is a very accurate, decent all-round weapon with balanced stats and low recoil, making it easy to use at all ranges. This may be beneficial for newer players who are struggling to control recoil or to pick the right engagements. However, the M27 is superseded at most ranges by other, more specialized weapons. Therefore, experienced players who are better at compensating for their weapon's weaknesses and know how to play to their weapon's strengths will likely give the M27 a pass in favor of more rewarding options. The combination of solid rate of fire, extreme accuracy but low damage and relatively quick reload make the M27 a solid medium range weapon that definitely has long range capabilities.

As of the January 26's patch, all assault rifles have reduced idle sway. The four-hit-kill range has been extended from 37.5 meters to 40 meters. The headshot multiplier has also been increased, allowing fewer shots to kill at longer ranges.



The M27 is only available in Nuketown Zombies and can be acquired from the Mystery Box for 950 points. It is a decent gun even without being Pack-a-Punched, as it has adequate reserve ammo and low recoil, although it has lower damage compared to other assault rifles. Because of this, it would benefit the player to obtain Double Tap Root Beer, as this increases damage and affects accuracy very little. The M27 can be proven quite useful and lasts up to later rounds as long as players can conserve ammo and go for headshots.

When Pack-a-Punched via the Pack-a-Punch Machine, it becomes the Mystifier. Its reserve ammo and damage are increased and a Reflex Sight is added. It can be Pack-a-Punched multiple times for 2000 points to cycle through attachments, including the Reflex Sight, MMS, Target Finder and EOTech sight and no attachments.

In the game mode Turned, it's the third weapon to be obtained if the player is a human.

The subject matter of this article was cut from the final version of a Call of Duty game.

The M27 was cut from Call of Duty: Black Ops III, with evidence of its existence found in the game files.

The weapon model is seen in-game, however. During the campaign mission Lotus Towers, a crate of M27s can be seen, but the player is unable to use them. The M27 can also be seen on the left screen of the Data Vault, alongside the VMP and Sheiva. Additionally, it can be seen in the armory section of the multiplayer map Rift.

In Der Eisendrache and Zetsubou No Shima, it is possible to obtain the M27 using console commands on PC, reusing the same stats as it did in Black Ops II. The Mystifier is also available through console commands, again reusing its Black Ops II stats.



Call of Duty: Black Ops II

  • If the player selects the M27 as their primary weapon, the character pulls the charging handle twice. A round can be seen ejecting from the chamber on the second pull but the ammo count will not go down.
    • If the player is using the Fast Hands perk, no round will be ejected during the animation.
  • The M27 has a unique foregrip when the Grip is attached. It is rubberized, longer than regular foregrips, and has an unusable flashlight attached to it.
  • When empty reloading, the cut-off word "odFISH" can be seen with a jellyfish on the charging handle.
  • On the left of the rear iron sight, the words 'Rusty Slums Arms' are visible. This is most easily seen while reloading.
  • The M27's serial number is "JW420975".
  • In the 'Domination Master' calling card, the shark can be seen wielding the M27 with the Grenade Launcher attached.
  • While sprinting, the M27 does not have an animation for switching from burst to automatic, but does have one for automatic to burst.
  • The M27 was to appear in TranZit, but was cut for unknown reasons. This is proven from a cut quote from Misty.
