Call of Duty: Black Ops 6 has a ton of different weapons to use, but as is usually the case, some rise above and become more popular. Right now, one of the most used is the XM4, in part, I guess, because it's one of the first ARs that you get your hands on. But it is also strikingly good.
It's so good, in fact, that the pro players for this season's Call of Duty League have already voted not to use in official play. It isn't banned, rather covered by a GA (Gentleman's Agreement) that league players won't use it. And certainly from my time in the game, there are plenty of folks using it in every match.
