M16A4



The Colt M16A4 is a lightweight, shoulder-fired, magazine-fed, gas-operated, air-cooled assault rifle chambered for 5.56x45mm rounds, and is currently the standard issue rifle of the United States Marine Corps and some United States Army units. It is featured in Call of Duty 4: Modern Warfare, the DS version, and Modern Warfare 2.

It is the current iteration of Eugene Stoner's original design, preceded by the -A3, -A2, and -A1 variations. The M16A4 rifle differs from the M16A2 in that it has a MIL-STD-1913 Picatinny rail under the removable carrying handle which allows different types of optics to be mounted on the top of the receiver, as well as a thicker barrel. There are also Picatinny rails mounted on the handguard to allow lasers, flashlights, and foregrips. The M16A4 is capable of semi-automatic and burst fire. The US military purchases M16A4s from Colt and FN Manufacturing with most M16s in recent orders being made by FN. In addition, M16 receivers for sniper variants and special purpose weapons have been procured from ArmaLite and Knight's Armament Company. The M16A4 is light and accurate, but requires frequent cleaning, partially because it is susceptible to dirt, but also because its internal mechanism lacks a piston; the gases strike the bolt of the rifle directly. This method of operation results in a lighter, simpler rifle, but causes fouling issues as carbon is blown into the chamber of the weapon.

Call of Duty 4: Modern Warfare
In singleplayer, the M16A4 can only be picked up during War Pig. It is dropped occasionally (sometimes with the M203) by dead Marines, and always uses iron sights. If you find a grenadier version and have found all the intel items, the M16 grenade launcher fires on full auto faster than any other grenade launchers in the game. The M16A4 in singleplayer has a fully automatic firing mode, though in reality the A4 variant features only three-round burst and semi-automatic fire. It is also used by Lt. Vasquez.

In multiplayer, the M16A4 is available at level 1 and fires in three-round bursts. It can be fitted with a Silencer, Red Dot Sight, ACOG Scope, and M203.

Usage
It is often recommended to use this weapon from a distance as it is not considered effective in close quarters combat. When fired from the hip while moving the M16A4 is wildly inaccurate. Unlike most other semi-automatics like the G3 or pistols, which can be fired as quickly as the user can pull the trigger, the M16A4 has a forced delay between bursts. This delay effectively lowers the rate of fire in terms of adjusting aim meaning that at close range if the first burst misses the user will be dead before getting off a second burst. However, Steady Aim shrinks the hip fire reticle to sizes comparable to SMGs making the weapon fairly accurate from the hip even while moving. Thus, even at close range, an M16A4 with Steady Aim and Stopping Power can still be very effective.

The M16A4 is exceptionally powerful because each bullet in the burst does 30-40 damage, meaning most of the kills will be one hit or two hit kills. When used with Stopping Power, the M16 is able to kill in one burst at any range provided that all three shots hit the target (only two are needed at medium and close range) and the target is not behind a wall or using Juggernaut.

Double Tap decreases the delay between the firing of each of the three bullets in a single burst and decreases the amount of time between bursts. With Double Tap, all of the rounds fired in a single burst are now fired with hardly any delay between shots. This can be somewhat useful in many situations, as there is a higher chance of all three bullets hitting the target and the shorter time between bursts makes the weapon more effective in CQB. However, Stopping Power is still considerably better as it will almost always kill faster while using less ammo. The only exception to this is Hardcore, where Stopping Power has no effect on the M16A4, as it only needs one shot to kill from any range, assuming the target is not using Juggernaut or behind cover. However, the 3 round burst still compensates for this, making stopping power completely useless in hardcore.

The M16A4 is widely considered to be one of the best assault rifles in the game due to its power, low recoil, lack of sway, quick reload, high ROF per burst, and easy conservation of ammunition due to its burst fire. This makes it popular to use, but is also frowned upon by some players due to its ease of use.

Call of Duty 4: Modern Warfare (Nintendo DS)
In the Nintendo DS version of Call of Duty 4: Modern Warfare, the M16A4 appears as one of the two assault rifles in game. The M16 bears a vague resemblance (though it can still be identified as a M16) to the one in the console versions, though it is fully automatic (like the M16s in Call of Duty 4 campaign mode). It has a much slower rate of fire, but it does more damage per bullet to compensate for this. In single player, the M16 is only found with a holographic sight, as opposed to iron sights in multiplayer. This doesn't matter, since the iron sights are just as accurate as the holographic sight, and provide a better peripheral view. In single player, the M16 is most effective at long range, though it is still effective at close-medium range. This all changes in multiplayer, as it is only effective at long ranges. It's low rate of fire prevents it from being effective at close range, unless the enemy doesn't see you. The M16 also has the third slowest melee speed, making it even less effective in close encounters.

Singleplayer
In the singleplayer Campaign, the M16A4 is seen in both American and Task Force 141 missions. It fires in bursts in both singleplayer and multiplayer, unlike its Call of Duty 4 counterpart which is fully automatic in single player.

Multiplayer
The M16A4 has returned in Call of Duty: Modern Warfare 2. It behaves similarly to the Call of Duty 4: Modern Warfare version with some small differences. It is now unlocked at level 40 in multiplayer and its reload animation is now identical to that of the M4A1 Carbine. To make it look more modernized, a Picatinny rail has been added to the carrying handle (this is, however, redundant as the handle itself is mounted on one). The rear sight aperture has been made thinner than the Call of Duty 4: Modern Warfare version, giving a cleaner, less cluttered sight picture. Also, camouflage is now only applied to the rail covers, the stock, the magazine and any attachment.

The FAMAS is similar to the M16A4 as they share nearly identical stats. The FAMAS takes 1.08 seconds longer to reload (.1.6s empty), but has less damage drop off than the M16A4, leading to an increase in medium range performance. When a Holographic Sight is attached to the M16A4, recoil is reduced.

Trivia

 * In Call of Duty 4, The words "BLUE4" (a reference to BluFor, the opposite of OpFor, which applies to all NATO forces) and "Property of U.S. Government, Caliber 5.55x45mm NATO, M4A1 Carbine" in bold blue letters is visible on the side of the M16A4. The M16 fires 5.56x45mm NATO cartridges (5.55 is likely a typo) and the M4 Carbine was derived from the M16 series. This error is fixed in Modern Warfare 2.


 * Individual bursts fire as fast as the P90 and M249 SAW, making it an unusually fast-firing Assault Rifle.


 * When mounting an alternate sight on either an M16 or M4 Carbine in Call of Duty 4, the front sight post and gas block are missing from the game model. Realistically, this would effectively make both of these direct impingement firearms bolt action weapons, which would require the charging handle to be pulled back after every shot. This modeling inaccuracy was fixed for the M4 carbine in Modern Warfare 2 but the mistake is still present on the M16 in-game model.


 * In Call of Duty 4, the M16A4 had its own reloading animation. In Modern Warfare 2, its reloading animation is identical to that of the M4A1.


 * In Call of Duty 4 Multiplayer, if the player attaches the grenade launcher to the M16A4, the heat shield will turn into the one that was used for mounting the M203 onto M16A2s. This is unnecessary, as the RAS used on the M16A4 is just as capable of mounting the M203. This does not necessarily indicate that it turns into an M16A2, since it is one part that is very easy to swap out, and it still has the A4's removable carrying handle. This is fixed in Modern Warfare 2, although it is technically not an error.


 * In Call of Duty 4, if the Infinite Ammo cheat is enabled and an M16 is picked up with the M203, the fully-automatic rate of fire of the grenade launcher is very, very fast and greatly surpasses that of the M4A1. Curiously, the M203 on the M4 Carbine and the GP-25 on the AK-47 have much slower fully-automatic rates of fire, about the same as the W1200's pump action.


 * The M16A4, AN-94, FAMAS, and the M93 Raffica are the only weapons in the Call of Duty series that fire in a burst firing mode.


 * The Call of Duty 4's campaign, the in-game model depicts the M16A4 having an A4 upper receiver, but an A1 lower receiver, which explains why the weapon has full-automatic firing in single player.
 * In Call of Duty 4, the M16A4 with Stopping Power as a perk can be a one round burst kill if the target is shot in the middle or above.


 * In Call of Duty 4: Modern Warfare (DS), the M16 has a Holographic in single player.


 * When an M203 is attached, the forward iron sight changes size. The reason for this change is that a flip-up leaf sight is added.


 * In Call of Duty 4 (DS), even though the M16 fires fully automatic for the player, allies fire it in three-round burst. This is the same with most weapons, even those used by enemies.


 * In Modern Warfare 2, the markings on the side of the M16A4 say, "Made By Infinity, Tool For Victory, U.S. No Refunds."


 * In the level War Pig, anytime the secondary weapon is an M16A4 Grenadier, the amount of rifle grenades increases, however, if you switch either the starting M4A1 Grenadier or the secondary M16A4 Grenadier with the non-grenadier version, you will lose a significant amount of grenades.


 * The rear iron sight in both games is in position for short range aiming, using the 0-200 yard aperture.


 * The M16A4 is not used by the U.S. Army Rangers, because they will be replacing the current M4 Carbine standard for the newer SCAR series. The M16A4, however, is used by some infantry units in the U.S. Army and is standard issue in the Marine Corps.
 * The M16A4 has been replaced by the M4A1 and SCAR-H in Modern Warfare 2 as the Rangers' standard issue, in fact they have donated their old '16s to the Afghan National Army.


 * In the Modern Warfare 2 level "Of Their Own Accord", an M16A4 with a Red Dot Sight can be found in the bunker at the beginning, and is sometimes dropped by soldiers in front of Whiskey Hotel.


 * The iron sights on the M16A4 in Call of Duty 4 limit peripheral vision and the front sight is slightly higher up than in Modern Warfare 2.


 * In both Modern Warfare games, setting the sensitivity to 10 and spinning to the right reveals a complete lack of texture on the right side of the gun, as it shouldn't technically be seen.


 * In Modern Warfare 2, when looking at the right side of the M16A4 in either third person or when dropped, there is no forward assist, but all other components to the right side of the receiver remain (ejection port, brass deflector, magazine release, etc).


 * In Modern Warfare 2, the rifle's rear sight is higher than it should be.


 * In Modern Warfare 2, if this weapon is picked up, or is taken out for the first time, the player will not pull the charging handle back. The M16 shares the same operation with the M4A1.


 * The soldier on the cover of Modern Warfare 2 carries a M16A4 with an AimPoint Comp2 sight, although this is strange because this sight is never actually featured in the game, as a generic red dot is used.


 * In both Modern Warfare games, the pickup icon for the M16A4 shows an M203 grenade launcher attached regardless of actual attachments.


 * In Modern Warfare 2's campaign, the M16A4 can only carry a maximum of four 40mm grenades when equipped with an M203, whereas weapons like the SCAR-H and M4A1 can hold a maximum of 11.
 * The barrel of the real-life M16A4 is 20" long and is correctly displayed in the Create-A-Class image. However, the barrel does not seem this long in-game.


 * The M16A4, along with the FAMAS, is one of the most inefficient weapons to use in Hardcore modes, due to the power of the weapon, only one bullet is needed to bring down a target at any range, so the remainder of the burst will go to waste. This does not apply if the enemy is using Last Stand/Final Stand, Painkiller, or Juggernaut.
