All MW3 guns & killstreaks: Complete Modern Warfare 3 weapons list

MW3 offers plenty of guns and killstreaks for you to try out, with its vast weapons list and wide range of scorestreaks being added to in newer seasons.

Killstreaks and guns are the backbones of every class, giving Modern Warfare 3 players the freedom to customize their loadouts to include whatever they want.

Some players may prefer using streaks that can be earned quickly, while others favor those that require more kills but can single-handedly turn the tide of a game. It’s a similar story with weapons, with each gun having its own unique strengths and weaknesses that you’ll have to master.

Before you can do any of that, though, you’ll first need to know what weapons and killstreaks are available as of Season 6, which added two new weapons and reintroduced the MGB.
