M16


 * For the modern variant, see M16A4.


 * For the rifle in the DS version, see M16A1.

The M16 is an assault rifle featured in Call of Duty: Black Ops.

Campaign
The M16 is fully automatic in the campaign. It is the starting weapon in Operation 40, where it is equipped with an ACOG scope and M203 and where it's found silenced in the hands of Carlos, as well as being the starting weapon in S.O.G., where it is equipped with a Masterkey. It can be found throughout S.O.G. with different attachments. An M16 can also be found in Crash Site off the bodies of dead teammates. Strangely, the M16 in this mission has no firing or reload sound (most likely a glitch). Overall, the M16 has low recoil, a high rate of fire, and medium damage.

Multiplayer
The M16 fires in three-round-bursts in multiplayer, like the M16A4. It is part of the default "Assault" class. After having unlocked Create-A-Class, it does not need to be purchased with CODPoints.

The weapon has high damage with low recoil, offset by mechanical burst-fire, meaning it is most effective at medium-long range, especially since it maintains its damage up to longer ranges than all other assault rifles. However, the forced delay between each burst makes it less effective than automatic weapons at close range. All three rounds must hit at close to medium range for a kill, while four rounds are needed for kills at long-range, meaning that usually two bursts are needed at long range. However, if all three rounds hit, and one of them is a headshot, then it is capable of a one-burst kill at long range. The M16 is medium popular online. Due to its burst fire, it is advised to use at medium range or longer, as at close range it will lose to any shotgun, sub-machine gun, or automatic assault rifle. It's advised to have dual wield pistols as secondaries to enhance the player's close-quarters abilities.

The M16 is, for the most part, the same as its Modern Warfare incarnations, although its default range is longer. It is, however, slightly less effective due to the lack of Stopping Power, as more than one burst on target is needed for a long-range kill.

The Infrared Scope and ACOG Scope actually lessen recoil, which is different from the rest of the weapons when equipped with those two attachments. The M16 with any attachment besides the grenade launcher has a solid color on the heat shield.

Attachments

Zombies
The M16 is available in Nazi Zombies, it can be bought off the wall for 1200 points. It is found right to the power in Kino Der Toten, in the tunnels in "Five", near Speed Cola in Ascension, and right where the Flinger is on Call of the Dead. Similar to Multiplayer, it is a three-round burst weapon. The M16 is useful in middle rounds. If going for headshots the M16 is useful up until round 10, where it should either be Pack-a-Punched, or replaced with a better weapon.

When upgraded in the Pack-A-Punch Machine, it becomes the "Skullcrusher," making it fully automatic, increasing damage (one-hit-headshot until round 8), and adding an under-barrel M203 Grenade Launcher. The Skullcrusher is useful if going for headshots up to rounds in the early twenties. The M203 is good for taking out large groups on zombies. However, it has a wide radius of splash damage that can also hurt the player, so the player should not use it in close range, unless one has PhD Flopper.

Trivia

 * An M16 equipped with a Flamethrower or Grenade Launcher attachment has a different hand-guard from the stock M16 hand-guard, being replaced with a heat shield. The Flamethrower's heat-shield is red, which cannot change with camouflage, whereas the grenade launcher's heat-shield will change.
 * In the campaign, an M16 can achieve "infinite" ammo. To do it, get any two M16s. The ammo counter will display 1023 rounds (if you have 1023+ rounds in both M16s together) and when you reload it will get back to 1023 again. Although, ammo isn't infinite. Two M16s can have up to 1320 (660*2) rounds, but, for some reason, ammo counter will only show 1023 (2^10-1). Once you *really* have 1023 rounds in reserve, the counter will work properly. The same goes for the Commando.
 * When applied with any camouflage, unless the weapon has a heat-shield from the Grenade Launcher or Flamethrower, the hand-guard will be a solid color rather than actually camouflaged.
 * The Create-A-Class picture shows a windage/elevation adjuster, but the in-game model doesn't have one.
 * The M16 is the only weapon whose centertime is increased with the addition of an ACOG or IR Scope, which decreases recoil.
 * During Killcams with the M16, sometimes when multiple bursts are fired, the audio become out of sync, and it fire some bullets without sound, and some burst with only the sound of two bullets.
 * The M16 firing mode is set to auto on the receiver. Also there are only auto, semi, and safe modes, no burst even though the M16 fires in bursts. Although it could be because the weapon uses the same texture as the one in campaign mode.
 * The HUD icon/killfeed icon of the M16, similar to the Commando, has a longer magazine than the actual in-game model.
 * In the Call of Duty: Black Ops Multiplayer loading screen one of the soldiers in the image is wielding a M16 with an ACOG Scope but instead of a removed carrying handle it is attached to the top of the carrying handle unlike in the actual game.
 * On the receiver, above the magazine, it says M16A1 CAL. 5.56 MM 915470. And on the other side, behind the magazine, it says Firearms Division Industries Hartford Conn. USA.
 * In the level "Crash Site" if the player kills a US Marine and picks up his M16, when the player shoots or reloads it, it does not make any noise.
 * Frank Woods uses an M16 in the mission "S.O.G.", and it jams at an inopportune moment. This is likely a reference to the U.S soldiers' hatred of the weapons tendency to jam.
 * In the multiplayer, although it would seem due to the forced burst function that the recoil is low, this rifle actually has the lowest centertime of all the high-power (40-30 damage) assault rifles, meaning that in full-auto, the rifle would have very high recoil.
 * The M16 and Commando have the same firing sound.
 * The game model uses a 20 round magazine, but it holds 30, the extended magazine attachment has the 30 round magazine model, but holds 45 rounds.
 * Any sight attachments do not become attached to the M16's hand rail, but rather replaces it directly.
 * When using the zipline on Call of The Dead while having an M16, the player still holds the weapon with both hands.
