How to Equip Muzzles

Unlock the Muzzle Slot for Your Gun

Before you can equip a Muzzle attachment for your gun in MW3, you will first need to unlock its Muzzle Slot. To unlock this attachment slot, you will need to earn Weapon XP for your chosen gun by using it in MW3 multiplayer matches, Zombies, or Warzone.

Equip a Muzzle via the Gunsmith

Once you have both the Muzzle Slot and a compatible Muzzle unlocked for your gun, you can customize your weapon and add the muzzle via the Gunsmith.

What are Muzzles?

Helps with Shooting Stability

Majority of the muzzle attachments in-game help with your gun's shooting stability. When equipped they often make it easier to control horizontal and vertical recoil at the cost of ADS weapon sway and ADS speed.

When to ADS and ADS Explained

Also Helps Conceal Gunshot Sounds and Muzzle Flashes

Some muzzle attachments will also help you become more stealthy in combat. Suppressors muffle the sound of your gunshots, while Flash Hiders conceal your muzzle flashes, making it harder for enemies to spot your firing position.
