Modern Warfare 3 features a variety of different multiplayer weapons that can be customized with attachments, proficiencies and camouflages. Each weapon in MW3 has to be leveled up to unlock their specific upgrades, but unfortunately this feature will not be seen in the ghosts guns list due to the new Create-A-Soldier system that was added from BO2. Once a weapon has been fully leveled up in MW3, it will unlock the golden camouflage for that specific weapon.
Weapon proficiencies give additional benefits, for example, once the Attachments proficiency has been unlocked, it allows you to equip two attachments to one primary weapon.
You can choose one primary and one secondary weapon for your class loadout.
