- in-game description
M4A1-Custom Crystal is an assault rifle variant of M4A1 Custom featured in CrossFire.
M4A1-Custom Crystal has the same feature as original M4A1-Custom, besides that it has a light blue crystallized texture to the gun.
One of the major characteristics about the M4A1-Custom Crystal is the firing rate, which has been increased, compared to other variants of M4A1-Custom.
However with higher rate of fire, it is compensated with decreased damage and slight increased recoil while firing, making it weaker than the original M4A1.
- Moderate high damage dealing.
- High accuracy.
- Medium rate of fire.
- Usable red dot sight.
- Higher accuracy when using red dot sight.
- Quiet firing noise
- Loses accuracy when sprayed for too long.
- Slow rate of fire when using red dot sight.

- Initially, the Bag Icon, Item Icon and HUD icon of this gun is actually a M4A1-S Crystal with the crystal-painted scope instead, notably its buttstock and silencer, but the in-game model is correct. This error was finally fixed after about 6 years.
