Building the best Echo 12 loadout in Black Ops 7 gives players one of the most unique weapons in the game to use, a double-barreled shotgun. The Echo 12 is arguably the best shotgun in the game, giving players a very strong gun in aggressive and close-quarter gameplay. It has a great range & damage, but must be cycled after two shots.

Below, you’ll find a complete breakdown of the Echo 12’s stats, every mastery camo available for the weapon, and optimized class setups for competitive, multiplayer, and zombies.
