The Gunsmith is a feature in Call of Duty: Black Ops III and Call of Duty: Modern Warfare. It allows the player to customize, view and build out their weapons incredibly precise, as well as select multiple attachments and optics.
Call of Duty: Black Ops IIIEdit
With Gunsmith, players can design and create cosmetic variants of pre-existing weapons outfitting their guns with the choice of five various attachments including an optical attachment and Paintjobs. Most weapon attachments have approximately four to five cosmetic variants which allows the player to further change the appearance of their weapon, along side these features players can name their weapon.
The players can make custom camos for their weapons to the top and sides with up to 64 layers, similarly to the emblem creator. The players can also inspect their weapons with camo and attachments on in full 3D and rename their weapons from the actual gun name to a custom, completely desired one. Weapon painting is absent on the Xbox 360 and PlayStation 3 versions of the game.
Call of Duty: Modern WarfareEdit
Gunsmith returns in Call of Duty: Modern Warfare, allowing the player to customize their gun with various attachments and Gun Perks. Attributes as "integral" to a gun as the barrel length and the caliber can be changed as well at higher levels, allowing for e.g. the starting 9mm SMG AUG to be turned into a 5.56 AR. Some of these changes, such as replacing the stock on a MP5, will change the weapon's name as well.
A few blueprints with advanced attachments are provided in the player's armory. Players can choose to use these pre-modified weapons in their loadouts while the base weapon itself has few modifications available, jump-starting their modification progress.
