Meta M4 Attachments in Warzone 2

The Sakin Tread-40 is an excellent muzzle to use on the M4 as it reduces vertical recoil by 22% and horizontal recoil by 13%. If you don’t have this, the FTAC Castle Comp, XTEN Ported 290, or Cronen OP44 are all great alternatives.

Next, the Hightower 20″ Barrel is by far the best M4 barrel for a couple of reasons. It reduces vertical and horizontal recoil by 9%, while increasing damage range and bullet velocity by 20%.

The Aim OP-V4 is our favorite optic due to the clear sight picture and low visual recoil, but feel free to choose whatever one you prefer!

Another must-have attachment is the 5.56 High Velocity ammunition. This is because it increases your bullet velocity by a whopping 44%!

Finally, we’ve opted for the 60 Round Mag so you can eliminate more enemies without having to reload!
