This M4 loadout minimizes recoil and maximizes ADS speed without making any considerable reductions in damage output. The reload speed of the M4 will be made quicker through the Fast Hands bonus perk. Players can also go behind enemy lines faster through the Double Time perk coupled with the Dead Silence field upgrade.
To maximize the full potential of this loadout, it is recommended for players to use an aggressive, run-and-gun playstyle with the intention of pushing enemy spawns without being detected.
