M13B = SIG-Sauer MCX VIRTUS (added with Season 1) Chimera = Honey Badger/SIG-Sauer MCX hybrid (added with 🌛 Season 1 Reloaded)

The Chimera is a curious case in Call Of Duty: 🌛 Modern Warfare 3, while it has the expected damage output of an assault rifle, its close-range optimisation is something more 🌛 akin to an SMG. Whilst there are even more powerful options out there, the Chimera remains as one of the 🌛 best assault rifles in Modern Warfare 3.
