The best guns in Modern Warfare 4 are the M4 and Kastov 762 assault rifles, the ISO Nightshade and X-58 NYX SMGs, and the Oris 8.6 marksman rifle. The M4 is the strongest all-round pick, while the ISO Nightshade rules close quarters. These are the weapons topping the meta now that Modern Warfare 4 has launched.
Here are the best MW4 guns right now, how we picked them, and the top weapon in each class.

How we picked them
The Modern Warfare 4 meta rewards fast time-to-kill, strong range control and aggressive close-quarters options, so the best guns are the ones that win the most gunfights across different maps and ranges. The M4 sits at the top because its base stats are reliable everywhere, the Kastov 762 hits harder for lane control, and the ISO Nightshade dominates close range with a high fire rate. The Oris 8.6 and Signal 50 cover the long-range picks. These rankings reflect the live launch meta — Modern Warfare 4 released on 23 October 2026 — and will keep shifting with each balance patch and the Season 1 update on 6 November.
