You load into Black Ops 7 or Warzone, take two steps, and the killcam shows the same thing again: the REV-46 deleting you up close. If you're still staring at a padlock in your create-a-class, it's annoying, full stop. Some players just shortcut the grind with CoD BO7 Boosting, but if you'd rather earn it yourself, you just need a clear plan and a bit of patience.

Battle Pass route (the usual way)

The most common unlock is the seasonal Battle Pass. The REV-46 tends to sit around the mid tiers, so you're not finishing the whole thing, but you are committing to regular play. Best tip: don't "play for XP," play for match time and completions. Queue modes that end fast, stay in the lobby, and knock out daily and weekly challenges without overthinking it. If you bounce between playlists a lot, you'll feel like you're working harder for the same progress. Stick to one or two modes you can win in, and the tiers tick up quicker than you'd expect.

Multiplayer armory challenges

If the season's gone, multiplayer usually offers an unlock challenge tied to the weapon class. Check the loadout menu and track it, because the wording matters. A "while sliding" kill often means the moment you're still in the slide animation, not the second you stand up. Same deal with "hipfire" or "tactical stance" tasks. Build a loadout that makes the challenge painless: run perks that keep you moving, use a laser or mobility attachments, and pick small maps where you're constantly taking close fights. You'll also want to avoid tilting—people chase headshots for an hour, get nothing, and quit. Take the easy kills first, then clean up the awkward requirements later.

Warzone unlocks without touching MP

Warzone challenges can be rough because you're doing chores while dodging third parties. The trick is to play like you're farming, not like you're trying to drop a highlight reel. Pick contracts you can finish safely, land near buy stations, and rotate early so the circle isn't forcing you into bad fights. If the task wants kills with a certain weapon type, grab a ground-loot version and take fights only when you've got cover and a clean exit. Squadding up helps a lot—one teammate can run contracts while the others watch angles, and you'll get attempts every match instead of dying once and going straight to the lobby.

Events, leveling it, and making it feel "right"

Keep an eye on limited-time events and Double XP weekends, because they quietly turn a week-long grind into a couple of evenings. Once the REV-46 is unlocked, level it with close-range fights first, then start stabilising it: recoil control, a cleaner sight picture, and enough mobility that it still wins those tight room pushes. It's the kind of gun that feels unfair when it's tuned, so if you're short on time and just want to get to the fun part, CoD BO7 Boosting for sale is an option some players use while they focus on actually learning the recoil and winning their fights.
