Modern Warfare 4 introduces Apex Attachments as a new layer of weapon progression. Available for supported weapons after reaching their required progression, these special upgrades work separately from standard Gunsmith attachments and can dramatically change how a weapon performs.
In CoD MW4, the M4 remains one of the most dependable Assault Rifles in the current Beta. Its main strength is versatility, allowing it to handle medium-range AR fights consistently while remaining effective across the mixed sightlines found on 6v6 maps.
In Modern Warfare 4, the Kastov Arc gives the Kastov 762 a utility-focused role instead of simply adding more conventional firepower. Its RF-pulse system is designed to disrupt infantry, electronic equipment, and vehicles, making it an interesting option for players who prefer tactical weapons.
