The M4 has 32 bullets in each magazine. One or two shots is enough to kill a bad guy. It has 100% accuracy (no spread), as if you were aiming down its unusable iron sights. You have infinite magazines, so you can finish the whole game without running out of bullets. Like in Call of Duty, reloading always fills the M4 to 32, even if there is no bullet in the chamber.
- The M4 in the HUD is depicted differently from the M4 in gameplay: the telescoping stock is omitted.
