Source review — 10 November 2026: This is an original-game loadout from the dated guide below. Accessible source pages confirm the listed weapon attachment names. Perks and equipment retain their original dated attribution; the source review does not imply hands-on testing or a fresh balance-patch analysis.
The M4 Carbine is the steady, full-auto option among Call of Duty 4's rifles: a Steam guide describes a high fire rate and almost no recoil in exchange for lower damage. Our verdict is to use the Red Dot Sight and stay at medium range. This applies to original 2007 multiplayer, with a perk set from a guide to the 2016 remaster.
Best M4 Carbine loadout
The Steam guide (updated February 2022) and KeenGamer's "greenie" class (13 July 2017) both pick the Red Dot Sight. KeenGamer supplies the perks, and it gives no fixed secondary or grenade.
| Slot | Pick | What it does |
|---|---|---|
| Attachment | Red Dot Sight | Steam guide uses it to maximise accuracy |
| Perk 1 | Bomb Squad | Shows enemy explosives from farther away |
| Perk 2 | Stopping Power | Raises weapon damage |
| Perk 3 | Dead Silence | Less noise from footsteps and kit |
Why this build works
Stopping Power covers the gun's main gap. Md2a's challenge guide (2008) gives it three of eight for damage, the lowest of the rifles there, with six of eight for accuracy and fire rate. KeenGamer's author avoids the Silencer because he feels it costs damage. The Steam guide warns that range drop-off is significant if you use the ACOG Scope.
How to play it
Pick medium-range fights, which the Steam guide expects you to win with this gun. KeenGamer says it suits every game mode. A Search and Destroy contributor to Md2a's guide recommends controlled shots, because the gun is not the strongest and spraying through a scope is inaccurate.
Alternative setups
- Stealth flanker (KeenGamer, 17 November 2016): Silencer, silenced USP .45, Bomb Squad, UAV Jammer, Extreme Conditioning, stun grenade.
- S&D overwatch (Md2a, 2008): ACOG Scope, C4 x2, Stopping Power, Extreme Conditioning or Dead Silence. The contributor names Overgrown, Backlot and Crash.
Unlock notes
Md2a and PlayStation Universe (1 November 2007) both list the M4 Carbine at level 10. Md2a gives the Red Dot Sight at 25 kills, the Silencer at 75 and the ACOG Scope at 150.
