CODLOCKEROpen the BO7 classes page and you’ll find two Mod 15 setups and an MPC build. If you’re used to a full Gunsmith menu, that can look like a small list.
Rules narrow the choices
Competitive classes have to fit the CDL rules and the teams’ gentlemen’s agreements, or GAs. Those agreements add restrictions on weapons and attachments beyond the official rules. With fewer options available, it’s common to see several players arrive at the same build.
The two Mod 15 options
The Quickstep Foregrip setup is recorded for players including Huke, HyDra and Cellium. The Fusion Barrel version appears on the pages for Dashy, Scrap and RenKoR.
The choice is between the movement-focused and range-focused versions listed on the site. Look at the attachment differences before choosing; a player using one version doesn’t establish that it’s better for every map or mode.
Trying them yourself
Both Mod 15 setups and the MPC build are on the classes page, with attachment lists and import codes. If you’re playing public matches, remember that you may have options available that the pros don’t use in competition.
