ACOG Scope

The  is an attachment featured 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: Black Ops: Declassified and Call of Duty: Black Ops II.

Overview
"The ACOG Scope provides mid-range magnification for precision fire over long distances"

- Call of Duty ELITE

The ACOG Scope provides a 2.4x magnification level in Call of Duty 4: Modern Warfare, Call of Duty: Modern Warfare 2, and Call of Duty: Modern Warfare 3, with the exception of the G3 in Call of Duty 4: Modern Warfare which has a 1.75x magnification level. In Call of Duty: Black Ops, the ACOG Scope provides a 1.75x magnification level on all weapons with this attachment available. Because of the higher magnification level, it is a useful attachment for enhancing the long range capabilities of said weapon. It is considered a long range alternative to the Red Dot Sight, the Holographic Sight, and the Reflex Sight. However, although the ACOG Scope offers a higher zoom and range bonuses, it slows down the time to aim down the sights on most weapons, with the only exception being in Call of Duty 4: Modern Warfare which speeds up the time to aim down the sights on Sniper Rifles and Light Machine Guns. The ACOG Scope also adds idle sway and visual recoil on all guns.

- Attachment description

The ACOG Scope only makes an appearance in multiplayer and is available for all Submachine Guns, Light Machine Guns, and Assault Rifles (with the exception of the MP44) by completing the Marksman III Challenge. It is also unlocked for Sniper Rifles after completing the Marksman I Challenge.

The reticle of the ACOG Scope is a glowing red chevron, the tip of which indicates where the player should aim. Attaching the ACOG Scope increases the amount and speed of idle sway on the gun (except on sniper rifles, where the sway speed is reduced). The scope also decreases peripheral vision, as the scope takes up more of the screen than if using regular Iron Sights or a Red Dot Sight. Also, on sniper rifles, the player cannot hold their breath to steady the aim, unlike with the default scope.

When equipped on the M40A3, the base damage is raised from 70 to 75. A hit from an M40A3 with the ACOG Scope and Stopping Power will always result in a one-hit-kill, unless the target is using Juggernaut, Last Stand, or if shooting through cover.

Call of Duty: Modern Warfare 2
The ACOG Scope is available for all assault rifles, submachine guns, and light machine guns once the Marksman IV Challenge is completed. For sniper rifles, the ACOG Scope is unlocked when the Marksman II Challenge is completed. Achieving 20 kills aiming down the ACOG Scope unlocks the Thermal Scope for that weapon.

The appearance of this ACOG Scope differs significantly from its earlier Call of Duty 4: Modern Warfare counterpart. The ACOG Scope's reticle is now more similar to the default sniper scope, albeit thicker. The ACOG Scope is also now featured with a yellow-orange dot in the center, which is where the player should aim. The L86 LSW has its own unique version of the ACOG Scope, called the SUSAT Scope, which provides slightly clearer vision in the form of a single post.

In addition, unlike in Call of Duty 4: Modern Warfare, the ACOG Scope does not add idle sway, although it will keep the standard sway of sniper rifles, and maintains the characteristic of not being able to be steadied on Sniper Rifles. When using the ACOG Scope, visual recoil is increased greatly, but actual recoil is only increased slightly. This lowers the effective range of a weapon when firing in full automatic, making controlled bursts more helpful.

The effectiveness of the ACOG Scope is barely hindered when an enemy sets off an EMP, because although the glowing dot is removed, the crosshairs can still be seen.

Call of Duty: Black Ops
The ACOG Scope returns in Call of Duty: Black Ops as the ACOG Sight, and is available in multiplayer. The ACOG Sight is available for all primary weapons, costing 2000 COD Points. The ACOG Sight is also available on the Python, making this the first (and currently only) time the ACOG Sight has been available on a handgun.

The default ACOG Sight used on most weapons can differ between a simple crosshair or a crosshair with a dot, depending on the weapon it is attached to. The AK-47, RPK, and the Galil use a completely different scope design, the PK-AV; the AUG uses its unique Swarovski Scope; the L96A1 and Enfield use the  SUSAT scope, and the Python uses its own unique scope. The reticle cannot be changed unlike the Red Dot Sight or Reflex.

In general, the scope is smaller and more cluttered than the variants in previous games. With the exception of sniper rifles, the ACOG Sight lacks idle sway but still increases recoil and the time it takes to aim down the sight is also slightly longer.

Call of Duty: Modern Warfare 3
The ACOG returns in Call of Duty: Modern Warfare 3, and is available on all primary weapons, except for the Riot Shield and shotguns.

Multiplayer
Reticle customization returns for Call of Duty: Modern Warfare 3, similar to that of the Reflex Sight and Red Dot Sight in Call of Duty: Black Ops but does not include different color options. The alternative reticles are the same as those available for the Red Dot Sight and Holographic Sight.

Similar to Call of Duty: Modern Warfare 2, the ACOG provides a 2.4x zoom when aiming through it at the cost of a slower aim time and increased visual recoil but no increase in idle sway. Unlike in Call of Duty: Modern Warfare 2, the sight is mostly electronic; there are no crosshairs. Therefore, using the ACOG when affected by an EMP is more hindering compared to its previous counterpart, since the reticle disappears completely.

The ACOG Scope is available at Weapon Proficiency Level 2 for sniper rifles, Weapon Proficiency Level 11 for assault rifles and light machine guns, and Weapon Proficiency Level 16 for submachine guns.

Survival Mode
The ACOG Scope is purchasable for all submachine guns, assault rifles, light machine guns, and sniper rifles in Survival Mode at Level 30 and costs $1250.

Call of Duty: Black Ops II
The ACOG Scope returns in Call of Duty: Black Ops II.

Singleplayer
The ACOG Scope can be selected for most weapons in the campaign. For the 1980s missions, it uses the same models as in Call of Duty: Black Ops. In 2025 missions, it uses a modern appearance.

Multiplayer
The ACOG Scope is unlocked once the weapon reaches a certain weapon level. Unlike previous titles, the ACOG Scope has no effect on the time to aim down the sights, making it a much more useful attachment in Call of Duty: Black Ops II. Another change since previous installments is that when the ACOG Scope is equipped on sniper rifles, the aim can be steadied. Despite there being no visual cue, if the hold breath button is held, the sway will steady and the character will breathe in the same way as with a regular scope. The reticule is once again customizable, but color is not. Unusually, when used on assault rifles and light machine guns, the center speed of the weapon is increased by 2%. This is the same effect that the Foregrip has, so using the foregrip alongside this attatchment will yeild a 4.04% increase in weapon center speed (this is multiplicative, not additive). Sniper rifles, however, get a 10% reduction in center speed, increasing the recoil of the weapon ever so slightly. This is less noticeable on bolt-action sniper rifles, however, because the reticle returns to its initial position before another shot can be fired.

Call of Duty 4: Modern Warfare

 * An ACOG scope attached to a M40A3 increases the minimum damage from 70 to 75, meaning when combined with Stopping Power, it kills with one hit to anywhere in the body, unless firing through cover or if the enemy is using Juggernaut or Last Stand.
 * When the Dragunov is given an ACOG Scope, the quick drop time is increased, meaning the player will throw grenades and switch to his secondary much slower.
 * When equipped on a G36C, the spread will disappear on the lens and the recoil will be more controllable.
 * This attachment is absent from the campaign.

Call of Duty: Modern Warfare 2

 * The ACOG Scope has an unusable back up iron sight on its left side.
 * When applied to the M4A1, the name changes to "M4 ACOG Sight" instead of M4A1 ACOG Sight.
 * When aiming down the sights of an AUG with a Swarovski scope, the scope comes forward and will pass through the gun.
 * The ACOG is used instead of the Swarovski Scope on the AUG HBAR, but the Swarovski Scope is used in the campaign and Special Ops only.
 * When attached to certain weapons, such as the ACR, the scope will have no sway or recoil.

Call of Duty: Black Ops

 * The Python is the only secondary weapon in the Call of Duty series to have an ACOG Sight as a possible attachment, and is the only secondary in the game to have any sight available. It is also the only weapon where the ACOG Sight  increases the maximum damage range and does not increase recoil.
 * When an ACOG Sight is equipped on the M16, it actually reduces recoil, despite the ACOG normally increasing it.
 * The Swarovski Scope actually removes the rails from the AUG, instead of being mounted on the rails like in Call of Duty: Modern Warfare 2.
 * The Swarovski Scope is the only ACOG Scope on which Gold Camouflage is applied.
 * On the Nintendo Wii version, the PK-AV scope is different.

Call of Duty: Modern Warfare 3

 * When attached to a weapon, the ACOG is named "ACOG Sight", but if used in conjunction with another attachment it is simply named "ACOG".
 * Players are now able to customize the reticle on the ACOG scope.
 * In the campaign and Special Ops, the ACOG sight can have its normal enhanced zoom, the zoom of a Red Dot Sight, or even a lesser zoom of it.
 * The ACOG Scope appears to have multiple spots of dirt, therefore making it more difficult to aim in dark areas.
 * In the Survival Mode Trailer, the ACOG sight's reticle could be seen without aiming down the sight; this however was later scrapped from the definitive game.

Call of Duty: Black Ops II

 * The aim down sight speed for the ACOG Sight in Call of Duty: Black Ops II is much quicker than in previous installments.
 * The ACOG Sight no longer reduces accuracy when aiming. In fact, it actually increases a weapon's center speed by 2%. This effect does not apply to the sniper rifles, however, as it decreases their center speeds by 10%.
 * In the campaign, if one applies any Camoflauge to a weapon with the ACOG Scope attached, the scope will always be white. However in multiplayer, if one applies any camouflage to a weapon with the ACOG Scope, it will also become camoflauged.
