A good assault rifle is essential to any BR player’s kit when it comes to chasing down victories with the squad. It’s far and away the best kind of weapon to use in battle royale for your primary slot.

Warzone’s roster of guns is massive, and it will only get bigger over time, so it’s important to know which weapons are worth leveling up, unlocking, and using in your loadout when it comes time to run from the gas circle and into enemy fire. A few simple attachments could spell the difference between winning and losing.

Here are the best assault rifles you can use in Warzone, along with a full set of attachments for each of them.
