Like the G36C, the M4A1 is not available without a Red Dot Sight or a substitute of it in the campaign, unless the player spawns a different version via the console in "Ultimatum", "All In", or "No Fighting In The War Room". The M4A1 SOPMOD with iron sights that is found in " Ultimatum" (via "give all" console command) has the correct pick-up icon for the default M4A1 SOPMOD. Captain Price always wields a suppressed M4A1 except in his flashback missions and Hunted. Marines use the M4A1 Grenadier in " The Bog", " War Pig" and " Shock & Awe". The SAS uses the M4A1 SOPMOD in "Blackout", " Safehouse", " Ultimatum", " All In" and " No Fighting In The War Room". The regular M4A1 is used by Force Recon Marines in the mission " Charlie Don't Surf" and by the SAS in " Hunted" and " Game Over". All variants are equipped with the AN/PEQ-2A.

The regular M4A1 is always equipped with a foregrip and a unique Reflex Sight, while the Grenadier variant is fitted with its grenade launcher and a Holographic Sight. The M4A1 is introduced in " Blackout" as the SOPMOD variant, supporting a Red Dot Sight, an AN/PEQ-2A laser module, a silencer and an M203.
