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. The M16A4 in singleplayer has a fully automatic firing mode though in reality the A4 variant features only three-round burst fire (but it is possible to modify one to fire fully automatically either with a lower receiver that accommodates full-auto or a little clever machining). 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. It is also fairly similar to the M4 Carbine, as it has the same appearance, the same iron sights, and they also share ammo with each other, as well as with the G36C, however, the M16 has noticably higher damage than the M4.
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. And 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 a Steady Aimed, Stopping Powered M16A4 user can be very effective if they can land the first, often deadly, burst.
The M16A4 is exceptionally powerful because all the bullets in the three rounds have a damage of 30-40 each 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 bullets fired in a single burst are now fired at almost the exact same time. 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, except in Hardcore modes.
The M16A4 is widely considered to be one of the best rifles in the game due to its power, accuracy (due to tiny recoil and no red dot sway), quick reload, relatively quiet report and mobility. This makes it popular to use, but is also frowned upon by some players due to the ease of achieving kills without putting much effort in, which is also the reason people use it. Some also choose to avoid it because of Juggernaut users.
Call Of Duty : Modern Warfare 2
The weapon has returned in Call of Duty: Modern Warfare 2. It behaves similarly to Call of Duty 4: Modern Warfare with some small differences. It is now unlocked at level 40 in multiplayer. Its reload animation is now identical to that of theM4A1 Carbine. To make it look more modernized, a Picatinny Rail has been placed on the carrying handle, and has a synthetic handguard with RIS Rails at the end. The rear sight aperture has been made thinner than the Call of Duty 4: Modern Warfare version, making using the iron sights much easier to operate. The M16A4 was previously not prevalent but is now very common in Modern Warfare 2 Multiplayer despite its higher level unlock and the general increase in killing speed of all other weapons.
The FAMAS is similar to the M16A4 as they share nearly identical stats. The FAMAS takes 1.08 seconds longer to reload (.16s empty), but has less damage drop off than the M16A4, leading to an increase in medium range performance. Also, when you attach a holographic sight to the M16A4, the recoil is reduced. In single player, the M16A4 is seen in both American and Task Force 141 missions, although the FAMAS is much more predominant. It fires in bursts in both singleplayer and multiplayer, unlike its Call of Duty 4 counterpart.
- This weapon was widely used during the Vietnam War and is still widely used today for its accuracy and damage.
- In COD4, the M16A4 with an M203 replaces the in-game model with an M16A2/M203. This is strange because the M16A4 would be able to accept an M203 Grenade Launcher without a barrel or handguard replacement due to its synthetic RIS Handguard. This is fixed in MW2 and the M16A4's M203 is now attached to the lower Picatinny Rail on the handguard. This was probably accidental anachronism by Infinity Ward.
- In Call of Duty 4, The words "BLUE4" (a reference to BluFor, the opposite of OpFor, which is applied 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.
- In Call of Duty 4, the M16 had its own reloading animation. In Modern Warfare 2, its reloading animation is the same as the M4A1.
- In multiplayer, if the player attaches the grenade launcher to the M16A4, the heat shield turns into the one that was used for mounting the M203 onto M16A2s. This is unnecessary, as the M5 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. In Modern Warfare 2, this feature is removed.
- In Call of Duty 4, if the Infinite Ammo cheat is enabled and an M16 is picked up with the M203, the full-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 full-automatic rates of fire, about the same as theW1200.
- The M16A4, FAMAS, and the M93 Raffica are the only weapons in the Call of Duty series that are capable of firing in bursts.
- The Call of Duty 4 in-game model depicted the M16A4 having A4 upper receiver, but has an A1 lower receiver, which explains why the weapon can go full-auto in single player.
- In Call of Duty 4: Modern Warfare (DS), the M16 has a Red Dot Sight in single player.
- When an M203 is attached the forward iron sight changes size.
- In Call of Duty 4 DS, even though the M16 fires fully automatic for the player, allies fire it in a three-round burst. This is the same with most weapons, even those used by enemies.
- In Modern Warfare 2, the side of the M16A4 says, "Made By Infinity, Tool For Victory, U.S. No Refunds".
- In Modern Warfare 2, the M16 is completely missing the upper receiver on the right.
- The M16A4 has a detachable carrying handle on the top of the gun (the sights), so that is why when attachments are added, the iron sights disappear.
- In Call of Duty 4, a Fully Automatic Version of the M16 can be found on the level 'War Pig'.
- In the level War Pig (level), anytime you switch your secondary weapon with an M16A4 Grenadier, the amount of grenades increases, however, if you switch either your M4A1 Grenadier or the M16A4 Grenadier with the non-grenadier version, you will lose a significant amount of grenades.
- If you pick up the M16A4 Grenadier in the level War Pig (level), and you enable the Infinite Ammo cheat, the M16A4 Grenadier's grenade launcher becomes fully automatic. It fires about 2-3 rounds per second. Most likely the developers forgot to make it semi-automatic.
- Also, note that the Iron Sight in both games are in position for long range aiming, a feature from the early M16A1's iron sight, which can be flipped up and down to compensate from lack of windage setting in the early M16 variants.
- In Modern Warfare 2, an R.I.S. rail can be seen attached to the carrying handle, which is pointless because it is just removed to accommodate a sight.
- The M16A4 is not used by the US Army Rangers since they are slowly replacing their aging M4s for the newer SCAR series. The M16A4, however, is used by some infantry units in the U.S. Army as well as the Marine Corps, as the A2 model was completely phased out.
- In the Modern Warfare 2 level "Of Their Own Accord", an M16A4 w/ Red Dot Sight can be found in the bunker in the beginning and dropped by soldiers in the 'killzone'.
- The iron sight on the M16A4 in Call of Duty 4 limits peripheral vision and the front sight is slightly higher up than in Modern Warfare 2.
- In MW2 and MW1, 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 M16 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 compared to the real AR-15/M16 and other games that feature the rifle.
- In Modern Warfare 2, if you pick up this weapon, or take it out for the first time, the player will not pull the charging handle back. Strangely though, since in the M4A1s animation he does, and M16A4 and M4A1 is operated nearly the same way.
