ACOG Sight

The ACOG Sight (Advanced Combat Optical Gunsight) is an attachment that appears in BlastGen. It is the sixth attachment unlocked.

Overview
The ACOG Sight is an optical attachment with 2.5x zoom, making it ideal for engaging at moderate ranges. It is unlocked after getting 100 kills while ADS with a Holographic Sight, which it fairly easy to complete. The ACOG Sight is also compatible with Sniper Rifles, allowing players to opt for a much closer range optic, and also facilitates quickscoping. The player can also hold their breath with the ACOG Sight, allowing for more precision shots. It should be noted that optics do not reduce recoil, so it is ill advised to attach the ACOG Sight to submachine guns, specifically the MAC-12, since it has a large amount of recoil.

Campaign
The ACOG Sight is rarely seen used by the enemy, but Marines carrying assault rifles and light machine guns with ACOG Sights is a common sight. Unlike in multiplayer, the ACOG Sight has no zoom in the Campaign, and has the same zoom as iron sights. This can be a hindrance to players who try to kill enemies from further ranges, so it is best to opt for a sniper rifle, since they have high zoom by default.

Trivia

 * If sensitivity is increased to High, and the player turns left, they can see the reticle of the ACOG Sight. The same is shared with the Holographic Sight.
 * Trijicon USA can be seen on the scope.
