Attachments (weapon proficiency)

Attachments is a Weapon Proficiency in Call of Duty: Modern Warfare 3.

It enables the player to equip two attachments on their gun at once, similar to Bling in Modern Warfare 2 and Warlord in Black Ops. The weapon using this proficiency will be called (name of gun) Custom. Its icon is a 2, hence that it lets the player have 2 attachments on their weapon. Nothing else is known at this time. The player will be able to combine the Grenade Launcher will other non-underbarrel attachments, unlike in Call of Duty Black Ops.
