M40A3

The M40A3 is a bolt-action sniper rifle featured in Call of Duty 4: Modern Warfare.

Call of Duty 4: Modern Warfare
The M40A3 is only available in Multiplayer. It is the first sniper rifle to be unlocked, and as with all sniper rifles it is best used at a long range. It is unlocked at rank 3, and is a favorite among experienced and inexperienced players alike.

The M40A3 is one of two bolt-action sniper rifles, the other one being the R700. It has low recoil, so it is easy to track targets if the first shot did not kill the target. It has a 5 round magazine that is loaded one round at a time. The M40A3 has one disadvantage that other sniper rifles do not have; it is comparatively difficult to use without Stopping Power. Without Stopping Power, the M40A3 is a one-shot kill only to the head and neck, and its rate of fire is too low to reliably two-shot kill. This means that Stopping Power is practically a necessity. This also means that the M40A3 is less than ideal for killing Juggernauts even when it has Stopping Power equipped, as Juggernaut and Stopping Power cancel each other out. However, with Stopping Power, the M40A3 is just as powerful as the R700 with Stopping Power and Barrett .50 Cal with Stopping Power against enemies that are not using Juggernaut.

The M40A3 has one unique feature not seen with any other weapon. When it is equipped with the ACOG, its base damage is raised from 70 to 75. This means that, when combined with Stopping Power, it is a one-shot-kill anywhere on a non-Juggernaut, and is still a one-shot-kill on Juggernauts when the round impacts on the neck or head. It also makes it easier to use the M40A3 at closer ranges and facilitates quick-scoping, due to the ACOG's reduced magnification and aiming time compared to the sniper scope, however recoil is increased significantly, and the scope will block your target if you happen to miss.

Call of Duty 4 DS
The M40A3 is available in the NDS version of Call of Duty 4 as one of the two sniper rifles in game. It looks similar to the one on the console versions, but sports a black color scheme instead of green. The M40A3 is a single-shot rifle as you have to reload after every shot, has a very slow rate of fire compared to the console version, and has no recoil at all when aiming down the scope. It also kills in one shot to any part of the body except when no-scoping as it sometimes takes two shots to kill while no-scoping.

Call of Duty: Modern Warfare: Mobilized
The M40A3 returns in Modern Warfare: Mobilized, as the only sniper rifle in game. Its 3-D model has been redesigned to resemble the M40A3 from Modern Warfare. Just like the other weapons featured in Mobilized, the M40A3 is more powerful than the console versions, being able to perform a one-shot kill to any part of the body. It also has near perfect (perfect when crouching) hip fire accuracy, making this sniper rifle even more effective at No Scoping. The only disadvantages are the fact that it can only carry up to 20 rounds of reserve ammunition and there are no crosshairs when the player isn't aiming down the scope.

Trivia

 * Because the M40A3's default color is green, Digital Camouflage can be used as an alternative to Woodland Camouflage in grassy environments.
 * The M40A3 can share ammo with the G3, R700, M21, and M14 in Call of Duty: Modern Warfare.
 * The M40A3 my have been originaly black, as the character models in the official Call of Duty 4 strategy guide wield black M40A3's. Also, in Call of Duty 4: Modern Warfare (Nintendo DS) and Modern Warfare: Mobilized the M40A3 sports a black color scheme as well.
