M16A4

The M16A4 is a selective-fire assault rifle capable of semi-automatic and three-round burst firing modes, and is an updated version of the M16A2 rifle. 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. There are also Picatinny rails mounted on the handguard to allow lasers, flashlights, foregrips, and grenade launchers. It is the current standard issue rifle of the US Marine Corps and some US Army units. The US military purchases M16A4s from both Colt and FN Manufacturing. 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 and simpler rifle, but causes reliability issues, as carbon is blown into the chamber of the weapon, resulting in frequent fouling.

History
dont use this gun with stoppping power you hoes!

Call of Duty 4
In Singleplayer, the M16A4 can only be picked up during War Pig (level). It is dropped occasionally (sometimes with the M203 grenade launcher) by dead Marines, and always uses iron sights. The M16A4 has a full automatic firing mode, which is inaccurate, as in reality the M16A4 does not feature full-automatic fire.

In Multiplayer, the M16A4 is available at level 1 and fires in three-round bursts. The M16 can be fitted with a suppressor, red dot sight, ACOG, and M203 grenade launcher, although realistically it should be allowed a grip in-game.

Using
When using the M16, it is often recommended to fire at a distance, as the M16's three-round burst is not very effective in close quarters combat. Steady Aim does a good job at making up for this, but should not be used as an actual tactic. When used with Stopping Power, the M16 is able to kill in one burst at any range. For this reason, along with the fact that is has no sway, little recoil, and a short reload time, it is widely considered to be an overpowered gun. Contrary to common belief, Double Tap does have an effect on the M16A4, as it decreases the delay between the firing of each of the three bullets in a single burst. Simply put, all of the bullets fired in a single burst are now fired at almost the same time. It can be extremely effective in multiplayer, as the effect allows all of the bullets fired to impact at almost the same time as the others, instead of one after the other in which case some or most bullets could be avoided even if one hit. In other words, usually all bullets fired will make impact if one of them hits. The Silencer also seems to decrease vertical recoil, the gun will still kick to the side however.

Countering
The M16 is used mainly a medium-long distance weapon, so CQB will give you the upper hand. The enemy will usually spray at you or switch to their secondary weapon, both have a opening were they can't attack you(unless they knife). Attacking the player at a distance can be done with other long rage, high accuracy weapons(like the G3,) but note that the M16 is the strongest of all of them and will dominate single fire rifles. Sniping is no problem against the M16, unless your in too close.

Trivia

 * The words "BLUE4" and "Property of U.S. Government, Caliber 5.56x45mm NATO, M4A1 Carbine" in bold blue letters is visible on the side of the M16A4. The M16 fires a 5.56mm round and is not a M4 Carbine as it says. Infinity Ward most likely used the same weapon skin for both the M4 and the M16A4.


 * It is important to note that individual bursts fire as fast as the P90 and M249, making it an unusually fast Assault Rifle.


 * In Multiplayer, if you attach the grenade launcher to the M16A4, it turns into the M16A2 model. You can tell because of the heat shield added over the handguard.
