The M4 assault rifle is the first weapon you will lay eyes on in Call of Duty: Warzone 2. It is the starting weapon of the M4 Platform and is also the default weapon all of your custom loadouts revert to.
You do not need to do anything to unlock the M4. It will be available from the start. Do also note that the M4 is the same as M4A1 which has been a prominent feature in the previous Call of Duty games.
The following guide will tell you more about the best M4 loadout in Call of Duty: Warzone 2.

Using Echoless-80 on M4 is like using steroids because it boosts several damage stats of this AR like Increased Damage, Range, and Bullet Velocity. This muzzle also comes with the added benefit of sound suppression.
A further boost in the range due to Hightower 20″ Barrel is most suitable for the long-range loadout of M4. The Barrel makes it easy to land shots in every range due to recoil smoothness.
The near-perfect vision of the Cronen Mini Pro allows you to find your targets fast with an unobstructed view. The downside is the reduced Aim Down Speed of the Assault Rifle.
FTAC Ripper 56 is attached in our loadout as the stock to ensure the most negligible recoil and most increased stability. Moreover, it also accounts for aiming idle stability, allowing you to land precise shots at longer ranges.
