- For a similar optical attachment, see Reflex Sight.
The Red Dot Sight appears as an attachment in Call of Duty 4: Modern Warfare, Call of Duty: Modern Warfare 2, Call of Duty: Black Ops, Call of Duty: Modern Warfare 3, Call of Duty: Modern Warfare 3: Defiance, Call of Duty Online, Call of Duty: Ghosts and Call of Duty: Advanced Warfare. Some versions of the game have a Reflex Sight, a depiction of an early Red Dot Sight.
Call of Duty 4: Modern Warfare
- "Replace the iron sights with a precision reflex sight."
- — Attachment description
Campaign
In the campaign, Red Dot Sights seen are on the M4A1 SOPMOD and the P90-SD. Additionally, there is also a tube-like Reflex Sight exclusive to campaign, unique to the standard M4A1 and the G36C.
Multiplayer
The Red Dot Sight is available for all weapons except Sniper Rifles, Pistols, and the MP44 assault rifle. When selected as a weapon attachment, the Red Dot Sight replaces the weapon's iron sights. The Red Dot Sight is obtained by completing the first marksman challenge of any Assault Rifle, Submachine Gun, Light Machine Gun, or Shotgun. The Red Dot Sight is popular because it allows full peripheral vision and is clearer and easier to use than iron sights and other optics. However, the Red Dot Sight does not actually increase the weapon's ADS accuracy, which is always actually infinite.
AK-47 changes
The Red Dot Sight has an adverse effect on the AK-47 whereby it reduces the minimum damage from 30 to 20, meaning that with the Red Dot Sight equipped, the AK-47 will require one more bullet to kill at longer ranges. This effect also happens if the Silencer is equipped.
Call of Duty: Modern Warfare 2
The Red Dot Sight has some changes. The new model is square, smaller, less obtrusive, and allows for a better peripheral view. For the most part, it is similar to the Red Dot Sight in Call of Duty 4: Modern Warfare. Some weapons now have their own unique Red Dot Sights; the TAR-21 uses the MARS Sight and the F2000 also uses its own unique Red Dot Sight. All Red Dot Sights, except for the F2000's, are disabled when an EMP is deployed. Getting 60 kills while aiming down the Red Dot Sight unlocks the Holographic Sight for primary weapons.
The key difference between the Holographic Sight and the Red Dot Sight is that the red dot is smaller which allows for better accuracy at range whereas the Holographic sits higher on the weapon and reduces the effects of the muzzle flash when a player is aiming down their sights. Some people find it easier to see their target and quickly find the reticle due to the translucent "cut-out" crosshair which is a small circle with a larger circle around it. Others find that the larger sight actually obscures the target making it hard to aim precisely and acquire targets at range. The larger circle is much closer to the smaller circle, which is why the larger one obscures the target so much. It has a thicker frame than the Red Dot Sight, again reducing visibility. The preference between this sight and Red Dot Sight depends on whether the player needs long range pinpoint accuracy and has time for the sway to settle or whether the player will be firing on the move. It is also important to note that on the sunny maps (such as Afghan), the Holographic Sight will sometimes appear to glare, making far shots difficult, especially against snipers who are difficult to see.
Two glitches to be aware of with the Red Dot Sight are on the FAL and the M93 Raffica. The FAL and M93 Raffica's Red Dot Sights do not show the true point of impact, as bullets will hit diagonally downwards to the right of the dot. If one wanted the Holographic Sight for these weapons, they will unfortunately have to use this sight, as both of these weapons have long-range capabilities that are hampered by this.
The Red Dot Sight proves to be one of the most popular attachments for the MG4, as it is the first replacement for the misaligned iron sights.
Due to the height of the Holographic Sight and its positioning, many will choose the type of sight depending on the sight on the gun. For example, for the UMP.45, where the sight is lower down (see image) many will choose a Holographic Sight over a Red Dot Sight, as the Holographic Sight does not block as much of the screen as it normally would. However, on weapons such as the AK-47 where the sight sits on top, many players will choose the Red Dot Sight instead, as the Holographic Sight will take up more space and obstruct the player's peripheral view. As well, the Holographic Sight is infinitely better on weapons where it has a beneficial side effect on (the lowered recoil of the M16A4 and the higher minimum damage of the FAL), as the Red Dot Sight does not give the same advantage (also to note that the latter has a misaligned sight).
TAR-21 Variant
The MARS Sight, also referred to as the "TAR-21 Red Dot Sight", has a different appearance as it looks somewhat similar to a Holographic Sight, but otherwise works similarly as a regular Red Dot Sight. The MARS Sight is only found in multiplayer, whereas in the campaign and in Special Ops the TAR-21s are found with the standard Red Dot Sight.
F2000 Variant
The Telescopic Sight, referred to as the "F2000 Scope" or the "F2000 Red Dot Sight", is the replacement for the standard RDS on the F2000. It is similar in appearance to the Call of Duty 4: Modern Warfare campaign's M4A1 (not including the M4A1 SOPMOD) and G36C tube-like Reflex Sight, though the F2000's is thicker and longer. The sight has a bit of a tint on the lens, which can hinder target acquisition. However, its main benefit is that it is immune to an EMP, and resistant against brightness, which allows for easier acquisition of targets in bright open areas. However, darker areas will be more challenging to acquire targets.

Call of Duty: Black Ops
The Red Dot Sight returns in Call of Duty: Black Ops, seen mounted on the Commando in the multiplayer teaser trailer. Unlike the Red Dot Sight seen in previous installments, this one has a different design, being rounder and more flush with the weapon. The player can customize the color and shape of the reticle along with the lens color. There are seven reticle colors and six lens colors. There are also many different reticles to choose from.
The AK-47, AK-74u and RPK use a special Russian Kobra Red Dot Sight which has a square frame (similarly to Modern Warfare 2's default Red Dot Sight). The Kobra has a larger lens than the regular variant, which allows for a slightly better sight picture compared to both the standard Red Dot Sight and the Reflex Sight. However, it is found rarely on these weapons, as most of them have attachments that serve a more important purpose than the Red Dot Sight.
Customization
- Main article: Reticle and Lens Customization
Each custom shape costs 
500. Including the default dot, there are 40 different shapes. The color of the reticle can also be changed for 500, with the possible lens colors being green, blue, purple, teal, yellow, red and orange. On the Nintendo Wii version, the Red Dot Sight and Reflex Sight cannot be customized.

Call of Duty: Modern Warfare 3
The Red Dot Sight returns in Call of Duty: Modern Warfare 3. It was first seen mounted on a silenced MP5 in the E3 reveal for Call of Duty: Modern Warfare 3. It looks identical to the Call of Duty 4: Modern Warfare variant. It was also spotted on an enemy AK-74u during the E3 reveal, and on an AK-47 in the mission "Black Tuesday".
Multiplayer
Assault rifles, submachine guns, and light machine guns unlock the Red Dot Sight at Weapon Level 2. Shotguns unlock it at Weapon Level 12, and Machine Pistols unlock it at Weapon Level 7. The Red Dot Sight will give a 1.35x zoom when aiming through it. Reticule variants can be unlocked by leveling up the weapon. Compared to the Holographic Sight, it is up to personal preference what the player likes to use better.
Survival Mode
The Red Dot Sight is available as weapon upgrade in Survival Mode at level 7 and costs $750. It can be purchased from the Weapon Armory. It is cheaper than the Holographic Sight while serving the same purpose.

Behind the Scenes
During the Survival trailer, it appeared that there were two types of Red Dot Sights; one similar to the Call of Duty 4: Modern Warfare version and one similar to the Call of Duty: Modern Warfare 2 version. In the final game, however, only the Call of Duty 4: Modern Warfare variant appears. In the Special Ops mission "Kill Switch" however, it is possible to find an AK-47 with a Call of Duty: Modern Warfare 2 Red Dot Sight with Digital Camo.
