Weapon Build Codes make sharing exact Gunsmith setups fast and error free. Each code is an alphanumeric string that records every attachment, barrel, optic, ammunition type, and tuning applied to a weapon. When a player copies a code, that string captures the full weapon build like a blueprint. When another player pastes the code, the game reads the string and applies the same parts to the chosen weapon, saving time that would otherwise go into manual tuning CoD BO7 Bot Lobby.

Copying a build is quick from the Gunsmith menu. Open the Gunsmith for the completed weapon, confirm every attachment and tuning is set the way it should be, then choose the option labeled Copy Build Code or Share Loadout. The game will place the code on the system clipboard so the player can paste it into chat, a post, or a message. The code can then be shared with teammates, social channels, or content communities so others can test the same setup immediately.

Importing a code is just as simple. In the Gunsmith, select the matching weapon platform and choose Import Build Code or Load Custom Mod via Code. Paste the string into the input field and confirm. The game will apply the attachments and tunings to the weapon automatically. If the weapon in the player’s inventory matches the code’s platform, the process finishes in seconds and the weapon is ready to use with the exact same stats and handling.

A key caveat is that build codes do not unlock locked gear. The game only applies attachments that the player has already earned. If the code lists a high-rank barrel or a special optic that the importing player has not yet unlocked, the Gunsmith will skip that slot and leave it empty. This means players should still work through attachment unlocks, or use modes that speed unlocks, before expecting a code to produce a fully matching weapon. For players who want to grind specific parts quickly, practicing in a Bot Lobby BO7 can help level attachments without the stress of ranked play.

Build codes help teams standardize their loadouts for a given map or mode. Sharing a drop-in link to a squad lets every teammate use the same tuning, which makes strategy and sightlines more reliable. Content creators and pro players can publish codes with their weapon reviews, giving followers a plug-and-play option to test the meta. Community sites also collect and tag codes by role, effective range, and recoil profile so players can search for a build that fits their style.
