"The Trijicon Advanced Combat Optical Gunsight is a fixed power telescopic scope originally designed for the M16 and M4. It is the only choice for marksman shooters who accept no compromises. " - In-game Description

The ACOG Scope is an American Telescopic Sight. It requires 430 kills to be unlocked or can be purchased with credits (CR).


The ACOG (Advanced Combat Optical Gunsight) is a series of optics manufactured by Trijicon. It was originally designed to be attached on the Picatinny rail of the M16 and M4. However ACOG mounts and adapters have been made so the optic can be used on a variety of weapons, as well as the ACOG being sold from the factory with different mounts.

Models provide fixed magnification levels, from 1.5x to 6x. Reticles are illuminated at night by an internal phosphor, and some have a daytime illuminator via a passive external fiber optic glass pipe or LED-illuminated using a battery.

Multiple reticle designs are available for most models. Some feature a bullet drop compensator or different reticle shapes such as a chevron. Some models incorporate crude ghost ring iron sights as a backup sight. Others include Docter or Trijicon reflex sights mounted on the top of the scope.[1]

In-Game Model

The model in-game is visually the 4x32 TA31RCO.[2] The reticle used is the TA648-308.[3] A chevron indicates the point of aim with the lines extending downwards provide bullet drop compensation.


General Information

The ACOG Scope is available for all primary weapons and is intended for mid to long range combat. It has a 3.8x magnification, which assists with target acquisition and shot accuracy at longer ranges. The sight is so zoomed in that the range markers are easily readable, despite them being so small and generally useless. Compared to the other medium range optics, the ACOG Scope has a much smaller field of view (FOV) as well as a much thicker body, which can make it difficult to use on some weapons. The ACOG Scope may be better than other medium range sights in certain situations as the ACOG Scope has slightly higher zoom more than its competitors.


The ACOG Scope is best suited for longer ranged engagements. A Designated Marksman Rifle or other long-ranged weapons suit the ACOG well. For example, the MK-11 and SKS sport high damage at long range and have good accuracy. Due to its high magnification level, it is well suited for these types of weapons, providing the necessary zoom to deal with targets at long range. However, weapons that mainly deal with shorter ranges, such as PDWs, certain assault rifles, and carbines can find the ACOG Scope harder to work with, as it adds more camera recoil to the weapon. Overall, this could be a problematic or powerful sight to use, depending on the player's playstyle. ACOG on sniper rifles have an opposite effect. Rather than increasing a weapon's long-range capabilities, it improves their medium-range capabilities. The ACOG scope offers a lower magnification level than a sniper rifle's default scope, and a faster aim-down-sights (ADS) time, improving a sniper's ability to react quickly.

Pros & Cons


  • Good target acquisition.
  • Higher level of magnification than similar scopes. (M145, C79, etc.)
  • Range markers help combatting bullet drop.


  • High kill unlock requirement.
  • Poor performance in Close-Quarters-Combat (CQC).
  • Higher visual recoil.
  • Slight reticle sway when aiming down sights.


  • The model in-game is visually the 4x32 TA31RCO which has a 4x zoom, however in-game it is given a 3.8x magnification.
    • Even more puzzling, the reticle used is the TA648-308, which is only available for the 6x model of the ACOG.[3]
  • The ACOG has the same screen zoom while ADS as the PK-A.
    • However, the PK-A does not have any magnification in real-life.
  • The ACOG was used as the default sight on the Railgun, a fictional gun that was found on the Base Luna map.
    • However, the ACOG on the Railgun had a 10x magnification akin to that of Sniper scopes.
  • Interestingly, many ACOG models controversially hid Bible references in their serial codes.
  • In real life, an ACOG scope is not cheap; its cheaper variants can cost over $2,000 USD.
  • The ACOG has been depicted in plenty of first person shooters, such as the Call Of Duty, Battlefield and Rainbow Six franchises, as well as games such as Counter Strike: Global Offensive.
    • However, the reticle of the scope in CS:GO is not the commonly used inverted chevron shape as seen in Phantom Forces, instead appearing as a singular dot - similar to red-dot-sights such as the Reflex, Coyote and PK-A..
