Every build on our Pro Meta Classes page includes a build code — a short string like A01-AV3HK-U2JA5-1. Here's what they are and how to use them.
Black Ops 7's gunsmith can export any weapon build as a shareable code. Import one and the game recreates the exact configuration — same attachments, same everything — with no manual setup. It's the fastest way to run precisely what the pros run, with zero transcription errors.
Open the Gunsmith on the weapon, look for the build code option (shown alongside the build code display), choose enter/import code, and type the code exactly as shown, dashes included. Confirm, and the build applies. If a code won't accept, the usual culprits are a typo — the codes are case-sensitive — or attachments you haven't unlocked yet at your current weapon level.
Competitive Call of Duty runs under CDL rules plus GAs — gentlemen's agreements between the pro teams that ban attachments and weapons considered unhealthy for competition, on top of the official ruleset. By the time the bans settle, the viable pool is tiny: two Mod 15 configurations and effectively one MPC build. That's why our classes page is short — it isn't a sample of what pros use, it's the entire competitive meta.
They work anywhere, but remember what they're optimized for: mirrored fights on competitive maps against the best players alive, under restriction. In public matches, attachments the pros have GA'd away might serve you better. Use the pro builds when you're practicing for ranked or scrims — that's the environment they're tuned for.
