User blog comment:AdvancedRookie/Activision hints at more frequent DLC and content variety/@comment-4103312-20120106192051/@comment-99.229.6.47-20120107223655

The Black Ops version of the FAMAS is ancient and not in production, so it couldn't be added. It would make MW3 gay like how Black Ops had weapons not even from its time period. We already have the Type 95 in MW3 which is the Chinese version of the FAMAS, so it wouldn't be needed anyway.
