Call of Duty: Modern Warfare 3 is well into the seventh week of its fifth season, and while most things seem to be going well, players aren't happy about the delay of the JAK Devastators, an AMP (Aftermarket Part) that will enable dual-wielding for the Reclaimer 18 shotgun. In previous installments of the franchise, players would have to level up their weapons to unlock new attachments. However, Call of Duty: Modern Warfare 3 changed the game by introducing universal attachments, meaning that when players unlock one, it's available for all other weapons that can fit it.
