M14


 * For the Call of Duty: Modern Warfare 2 variant, see M14 EBR.

The M14 is an Assault Rifle featured in Call of Duty 4: Modern Warfare.

In Game
The M14 cannot be obtained in the Call of Duty 4: Modern Warfare single player campaign. In multiplayer, the M14 is a modernized model, with a Knights Armaments RAS (Rail Adapter System) Fore end, an RAS scope mount, a shorter barrel, heat shields, and synthetic furniture distinguishing it from its wooden-stocked ancestor. The M14 in-game is featured as a Semi-automatic rifle, with high stopping power, accuracy and recoil as well as a longer effective range compared to other assault rifles. It can be modified with a Grenade Launcher, Red Dot Sight, Suppressor, and an ACOG scope.

Multiplayer Tactics
The M14 is considered to be a "love it or hate it" or make/break weapon. Players will usually place the M14 on two extremes as a preferred (for high stopping power) or a non preferred weapon (for high recoil and manual rate of fire.) With Stopping Power, it can kill in two hits at any range, or one hit if shot in the head within its maximum damage range. however the m14 benefit less from stopping power than most gun. This is due to the 1.5x head multiplier which is unique to sniper rifles and the M14. Similar to the G3 in Hardcore mode, it is a popular weapon, due to the fact that it can drop any player in one shot. Unlike the G3, it will also, without Stopping Power, kill a Juggernaut in one shot at any range in Hardcore.

Adding the ACOG Scope to the M14 makes it very similar to an M21 with ACOG, but with less damage and more recoil. For this reason the M21 with an ACOG Scope is considered superior by most, as its cons are lower hip accuracy and less ammo, which are worth lower recoil and higher damage for long range combat. Also, on the SAS/Spetsnaz matches, a player using an M21 with ACOG gains the ghillie suit, while a player using an M14 ACOG doesn't, making the M21 a better choice.

The M14 with a suppressor has been acknowledged by many players as being the closest gun to a silenced sniper rifle you can get. However, this tactic is more suited to mid-long range sniping as opposed to very long range sniping due to the lack of an actual scope, the bulky iron sights, and the lack of a one shot kill ability. The suppressor can also be helpful with clearing the iron sights. When used it eliminates muzzle flash, providing for better target visibility.

Trivia

 * Using the grenade launcher attachment makes the player reload the weapon differently.
 * The actual reload time and the reloading animation for a loaded reload are about 1.5 sec off, meaning you actually reload before the magazine is even inserted.
 * The M14 has the same in-game model as the M21.
 * The M14 shares ammo with the M21, R700, M40A3 and the G3.
 * The M14 is very effective in Hardcore modes due to the fact that it can kill with 1 bullet.
