Before you can equip a barrel attachment for your gun in MW3, you will first need to unlock its Barrel 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.
Once you have both the Barrel Slot and a compatible gun barrel unlocked for your gun, you can customize your weapon and add the barrel via the Gunsmith.
Barrels primarily modify the effective range of your gun, in-game. Longer barrels offer more bullet velocity and damage at the cost of poor handling at close-quarters, while shorter barrels offer better handling at the cost of effective range.
