It will. It was used in Call of Duty XP's livestream.
The red dot sight from Call of Duty: Modern Warfare 2 was only available during the builds of MW3 and was never actually released for the game. For unknown reasons the red dot sight from MW2 was cut and they used a similar model from the original Modern Warfare but with changes. But an AK-47 with the MW2 red dot sight can be found in MW3 in the spec ops mission "Kill Switch".
