Assault rifles will always be a go-to weapon class in any FPS, and in Call of Duty, the best assault rifles in MW3 are a familiar list for many.

MW3 has its own new weapons and some of them are incredible, but don’t forget that Modern Warfare 2’s “Carry Forward” system means that MW3 also includes every gun you unlocked in 2022’s game. So if you want to, you can continue wreaking havoc with your favorite guns from MW2 as well.

Here are all of the meta assault rifles in MW3 right now.

Best ARs in MW3

The current best assault rifle in MW3 is the Holger 556, followed closely by the MCW. But don’t forget about all of the MW2 ARs, either. There’s plenty to choose from, and many of them will help you dominate online.

  • Optic: Slate Reflector
  • Underbarrel: Kimura RYN-03 Vertical Grip
  • Ammunition: 5.56 High Velocity
  • Rear Grip: Morn-20 Grip

MCW
