Both the ACR and the MP7 lack any visual recoil, both kill very quickly, both boast large magazines and fast(ish) fire rates, both have good enough damage, both are incredibly accurate, both are reasonably good at range and both are often brought through into the next prestige, boosting overusage (leading to the AK74-u issue from Black Ops).

As for the FMG9 Akimbo, they still retain a near unstoppable dominance when used, their damage combined with their speed is frightening, their only downside is major recoil, lack of long range ability and the first time you pull them out they act like Transformers, they aren't used as much, but it doesn't change their dominance. They can also be used in conjunction with a riot shield, effectively using them as a primary weapon without Overkill and being able to use another Perk 2.
