Hey TheGhost4G,
Thanks for posting! Which platform are you using and how long have you been experiencing this lag for? Playstation 3, Playstation 4, Xbox 360 and Xbox One are currently at Defcon 4 so you may experiencing the slight lag due to that, you can check current status here Call of Duty®: Ghosts || Game Status. Also, have you tried using a different controller? Please feel free to try crazycanuk suggestion as well.
