The Magnifier is a new attachment introduced in Call of Duty: Modern Warfare 3 which has the ability to change from a Holographic Sight to a magnified Holographic sight. It was seen attached to the M4A1 in the reveal trailer. It seems to be a Holographic Sight with a foldable magnifier behind it. The magnifier can flip from the right side to the top of the weapon, magnifying the reticle of the holographic sight and making the ADS similar to the Modern Warfare ACOG. The magnifier however, obscures most of the view, limiting peripheral vision. It is unknown if the magnifier comes with or seperate from the holographic sight.
