No change to the M4A1-S’s numbers in Valve’s file since May 2024.

CS2 weapon · Rifle · CT side M4A1-S

Valve: “Precise, silent, tracer-free.” With a smaller magazine than its unmuffled counterpart, the silenced M4A1 provides quieter shots with less recoil and better accuracy.

What beats the M4A1-S?

Weapon · edge30 m · headCost
Hits to kill from Valve’s file at your distance and armour — not win rates. Shotguns left out: pellets decide.

Economy context

  • M4A1-S + Kevlar$3,550$550 left
  • M4A1-S alone$2,900$1,200 left

Kill reward $300 — 10 kills pay the gun back. Armour: Kevlar $650, with helmet $1,000 (Valve’s items_game.txt).

Counterplay tips

  • Fight it beyond 28.22 m: past its standing accurate range even the first shot is not sure to land.
  • Catch it moving: on the move its first shot is only sure within 1.24 m.
  • It needs 5 chest hits at 15 m against armour — trade it rather than duel alone.
  • It moves at 225 u/s — expect it to reposition quickly.
  • Drop its holder first: they lose a $2,900 gun, and each kill it makes pays them $300.

No — 2 hits to a helmeted head at 30 m (79 each).
