M4A1-S — CS2 Damage Breakdown
Per-hitbox damage, armour penetration and shots-to-kill for the M4A1-S in Counter-Strike 2. Want a custom range or armour state? Use the calculator.
Below are the commonly-cited damage figures for the M4A1-S against an unarmoured target at close range. For a specific distance, hitbox and Kevlar state, run the numbers in the CS2 damage calculator.
Base damage
The M4A1-S deals a base of 38 damage to an unarmoured chest at point-blank range. Every other hitbox scales from this number.
Hitbox multipliers & damage
| Hitbox | Multiplier | Damage (unarmoured) | Shots to kill |
|---|---|---|---|
| Head | x4 | 152 | 1 |
| Chest / Arms | x1 | 38 | 3 |
| Stomach | x1.25 | 48 | 3 |
| Legs | x0.75 | 29 | 4 |
Shots-to-kill assumes a full 100 HP target and no armour. Against Kevlar, chest and stomach shots take more hits because some damage is absorbed.
Armour penetration
The M4A1-S retains roughly 70% of its damage against a Kevlar vest (community-derived figure). Higher penetration means the vest does less to save the target on body shots. The helmet, separately, is what cuts headshot damage.
The falloff caveat
These numbers are point-blank. Most weapons lose damage over distance, and the M4A1-S is modelled here with a simplified per-metre falloff rather than Valve's exact internal curve. Treat the figures as close guides for learning, not precise in-game guarantees — see CS2 damage falloff by distance for how range changes the maths.
