- Weapon description

M4A1-Custom is a silenced variant of M4A1 in CrossFire.


M4A1-Custom is an advanced version of the standard M4A1, boasting superior accuracy and significantly less recoil. It is equipped with a suppressor, red dot sight, folding stock, and an unusable laser sight & flashlight. The silencer is great for concealing the user's location while firing.

The red dot sight also gives the user almost 100% accuracy whilst aiming down sights, which makes this a great weapon at both long and close range. However, the gun's rate of fire slightly decreases while using the red dot.


  • Moderate-high damage dealing.
  • High accuracy.
  • Medium rate of fire.
  • Usable red dot sight.
  • Higher accuracy when using red dot sight.
