ACOG Scope

The Trijicon Advanced Combat Optical Gunsight, or ACOG, TA31RCO is an optic available in Call of Duty 4: Modern Warfare. It can be used on any Assault Rifle (excluding the MP44), Light Machine Gun, or Sub-Machine Gun after the player has unlocked all Marksman challenges for it (150 kills). It can also be used on a Sniper Rifle in lieu of its standard telescopic sight after 100 kills. Equipped as the weapon attachment, it replaces the iron sights or sniper scope and provides a 2x zoom. The increased zoom improves visibility over range, but increases idle sway - reducing accuracy. Note that effective bullet range is not affected by this attachment (all guns except shotguns have infinite range). The reticle is a red chevron (upside-down V).

Advantages

 * The ACOG makes tracking moving targets (at long distances) much easier, since the target is magnified and while the gun is moving there is slightly less sway.


 * Increased zoom means better visibility when shooting over long distances.


 * The M40A3's base damage is raised to 75 with an ACOG.


 * It converts sniper rifles into regular rifles, making them powerful semi-automatic or bolt-action substitutes.


 * The G36C has almost no idle sway increase with an ACOG.


 * The ACOG makes it easier to use a sniper in mid-range combat.


 * It is faster to zoom in with an ACOG than a regular sniper scope.

Drawbacks

 * Due to increased sway, (in comparison to iron and  Dot Sights), it is terrible for pin point shooting.


 * It does not allow sniper rifles to be steadied. Also, when prone, you cannot in while moving, which you can do with standard sniper scopes.


 * The opaque surroundings of the scope blocks the player's peripheral vision.


 * It takes longer to sight through the scope compared to iron sights or the Red Dot Sight.


 * The and zoom on a sniper rifle are lowered considerably.


 * The ACOG is not recommended for close combat, as it zooms too close for visible advantage.
