Assault rifles are consistently a strong choice in Modern Warfare 3, offering an ideal balance of damage, ease of use, and effective range.

This is a key reason why assault rifles have always been the most popular weapon class in Call of Duty. Their versatility makes them competitive on every map in the franchise, unmatched by any other class.

This year's game continues this trend, with ARs dominating the list of most-used guns in MW3. Whether you’re playing casually or in Ranked Play, an assault rifle is always a solid option.

However, it’s important to stick to top-tier assault rifles that define the meta. Not all ARs are created equal, and some aren't even viable. Staying updated with the constant buffs and nerfs that change the meta each season can be challenging.
