"Automatic assault rifle featuring a short stroke piston system that keeps the fire rate high and the recoil low."
— Description


The M13 is a Tempus Armament assault rifle featured in Call of Duty: Modern Warfare.

Campaign[edit | edit source]

The M13 is used by the SAS during the Campaign. In Cleaning house, A Semi Automatic only version is the player's starting weapon.

Multiplayer[edit | edit source]

The M13 is a fully-automatic assault rifle unlocked at rank 39. It comes with low damage for an assault rifle (and by most other standards). It requires a minimum of 5 shots to kill out to 30 meters, though this can be lowered to 4 or even 3 shots with headshots. Past this distance it will require 6 shots. Fortunately, the M13 comes with a lofty fire rate of 923 RPM. This is faster than all other fully-automatic assault rifles, LMGs, and most SMGs. Time-to-kill is not particularly fast due to needing several shots to kill, but the weapon’s rate of fire makes it more forgiving when missing a couple of shots.

The M13 also features generally favorable handling for an assault rifle. Move speed is fair, ADS speed is among the fastest in the class, and hipfire spread is average yet workable thanks to the high rate of fire. The gun also comes with a standard 30 round magazine, but the high rate of fire and low damage mean that this ammo will be depleted rapidly. The M13 also has fairly controllable recoil. Though the gun will drift upwards due to the high fire rate, recoil under fully-automatic fire is predictable out to midrange. Overall, the weapon has a host of traits that make it pretty flexible both up close and out to medium distances. It is one of the nimbler assault rifles, but its time-to-kill is can be lacking if the player does not achieve a headshot.

It also comes with an interesting variety of attachments to tailor the gun to a variety of situations. The Tempus Mini barrel will speed up ADS and move speed but slightly hamper long range performance. The M13 will generally handle faster like an SMG. This can be combined with the M13 Skeleton Stock for a mobile ADS-centric build or No Stock and Stippled Grip Tape for maximum mobility in tight spaces. In contrast, the Tempus Marksman will noticeably boost damage range and reduce recoil for stronger performance far away. The Tempus Cyclone is an interesting choice as it provides an integrated suppressor that increases bullet velocity with only a minor ADS speed penalty. There’s also the usual variety of muzzles, optics, and underbarrel attachments for the assault rifle class.

Adding an extended magazine is a great way to satiate the M13’s voracious appetite for ammunition. Reloads will be less frequent and the gun will have more reserve ammo, which is essential for prolonged streaks. However, the M13 also has a unique magazine altering attachment: .300 Blackout 30-Round Mags. This attachment will grant 25% extra range and remove both bullet tracers and the skulls that appear above killed enemies. These benefits are useful for more stealthy playstyles, especially for flanking opponents. Combining this with a suppressor or the Tempus Cyclone barrel will make for a deadly and silent build that can harass enemies while avoiding detection.
