Black Ops 7: Tier 100 C9 Blueprint Is Still the Most Fun Weapons
This article breaks down why the Yaja Bone Carbine is surprisingly worth unlocking in 2024's final BO6 season, the full loadout that powered four nuke games, how it performs across different maps.
A Tier 100 Reward With Real Value - Because of the Iron Sights
Most tier-100 blueprints in recent years have been cosmetic first, functional second. The Yaja Bone Carbine flips that trend. While the name might be impossible for most players to pronounce, the blueprint radically improves the feel of the C9 by swapping its chunky default irons for a much sleeker, cleaner sight picture. Gunfights simply feel better. Target acquisition becomes snappier.
The weapon looks and plays different without compromising the identity of the C9.
On top of that, the blueprint includes:
Custom organic-bone-style weapon skin
Fiery red tracer rounds
Unique death effects
A glowing extended mag
A matching Tier-100 melee weapon (Yaja Sword)
BlackCell variants, calling cards, emblem, 200 CP, and more
For a late-cycle battle pass reward, this blueprint is unusually high-quality-and because double battle pass XP recently ran for almost an entire week, many players were able to finish the pass in time to unlock it.
The Loadout: Why This 10-Attachment Setup Is So Effective
While the blueprint looks stylish on its own, the real power comes from pairing its featured attachments with a sweaty, high-performance C9 setup. Using the blueprint as the base, the loadout below produced multiple nukes-from Hardpoint comebacks to domination blowouts to nail-biting 30-kill streaks against heavy shotgun lobbies.
Primary: Yaja Bone Carbine (C9)
Barrel: Long Barrel
Boosts damage range
Gives the C9 extra reach, making mid-range fights more consistent
Also maintains the aesthetic of the blueprint
Underbarrel: Ranger Foregrip
Horizontal recoil control
Slight sprinting movement buff
Helps keep accuracy tight during mid-fight movement
Magazine: Extended Mag 2
Glowing red flares match the blueprint
Enables multi-kill chains without constant reloads
Crucial for nuke streak consistency
Rear Grip: Ergonomic Slide Grip
Faster ADS
Faster ready-speed after sliding
Key for aggressive playstyles
Stock: Infiltrator Stock
Massive strafing buff
Helps win head-glitches and longer duels
Feels "unmatched" in terms of mobility
Muzzle: Compensator
Vertical recoil control
Makes the gun beam at longer distances
Laser: Target Laser
Aim-walking steadiness
Combos with strafing to make the gun feel "locked in"
Trigger/Internals: Recoil Springs
Minimizes weapon bounce
Turns the C9 into an absolute laser
Secondary: Graco
The Graco remains one of the strongest and most reliable sidearms in BO6-perfect for emergency reload situations on nuke streaks.
Equipment
Stimshot (fast healing)
Blast Traps (the best lethal in BO6)
Perks
Scrambler - jams enemy radar, essential for flanks
Scavenger - keeps ammo stocked during long streaks
Hunter's Instinct - reveals the next target after each kill
Slipstream - movement speed boost and tax removal
It's a sweaty, high-mobility, high-tempo setup built for chaining kills, taking over hardpoints, and farming spawns.
On-Map Performance: Four Nukes, Multiple 100-Kill Games, and Clutch Comebacks
Across the testing sessions that inspired this analysis, the Yaja Bone Carbine produced four separate nuke games-each with different pacing, lobbies, and challenges. The gun remained consistent even in situations where enemies used:
Fire Maelstrom shotguns
Olympia dual-slug builds
Jackal spam
High-mobility SMG rushers
Snipers
The standout theme?
The C9 never struggled with control, even under pressure.
Below is a breakdown of some of the biggest highlights.Nuke #1: A Hardpoint Miracle With Teammates Who Actually Listened
The first nuke came during a chaotic hardpoint match where enemies repeatedly hunted the player specifically, often sprinting across the map just to shut down streaks. After dozens of tense firefights, a clutch HARP (advanced UAV) flipped momentum. The player needed teammates to step off the hill to extend the match-and surprisingly, they did.
Final stats:
109 kills, 18 deaths
1 nuke
Massive late-game streak to close out the win
In a year full of random teammates ruining streaks by sitting on the hill, this one was the opposite.
Nuke #2: First Ever Nuke on a New Map
On a map with awkward lighting and learning-curve spawns, the Yaja Bone Carbine still delivered a 30-kill streak. Shotguns and snipers tried repeatedly to shut things down, but once the HARP went online, the map fell apart for the enemy team.
Best moment:
A brutal firefight where the player survived multiple rushes from a shotgun squad and pieced together the final 10 kills in chaotic close-quarters room fights.
Nuke #3: A Clutch Nuke After Overcoming Spawn Chaos and Teammate Mistakes
One of the most impressive games came in Domination, where teammates repeatedly pushed too far into enemy territory, causing spawn flips and ruining streaks. Despite this, the Yaja Bone Carbine shredded opponents with tracer-backed beams.
A late-game War Machine multi-kill stabilized the match, and a perfectly timed reload in the middle of a 27-28 streak sequence saved the nuke.
Final stats:
87-7
1 clutch nuke
Heavy killchain moments despite War Machine timing risks
Nuke #4: The Double Nuke - Against Shotgunners and a Dedicated Sniper
The final gameplay was the wildest. Shotguns everywhere. Two ASGs. An Olympia. A cracked sniper lasering head glitches. And yet, the Yaja Bone Carbine managed:
A first nuke, then
A second brutal nuke, only being shut down after hitting Brutal #2
The kicker?
The player didn't even realize they were on a second streak until hitting 25 kills.
You know a weapon is strong when a lobby built to counter aggressive red-gun play still gets melted.
Blueprint Cosmetics: Tracers and Death Effects That Actually Feel Premium
A lot of recent tracer packs have felt copy-pasted across multiple weapons, but this blueprint's tracers stand out. The glowing red flares match the magazine design, and the organic-bone aesthetic feels more fitting for a Tier-100 item than many previous passes.
The death effects-fiery, animated, and loud-helped create visibility when chaining multi-kills and clearing hardpoints.
Is the Tier 100 Yaja Bone Carbine Worth Unlocking in BO6?
Surprisingly, yes-and not just because of cosmetics.
Improve C9 handling
Offer clean, competitive iron sights
Provide premium tracers and effects
Maintain a cohesive aesthetic
Deliver an extremely strong end-of-gameplay feel
When a battle pass gives a blueprint that helps achieve multiple nukes, multiple 100-kill games, and consistent map control, it's hard to argue it isn't worth it.
Final Verdict:
Most players have moved on to camo grinds, final weapon cleans, more CoD BO7 Bot Lobbies and CoD Next hype. But the Yaja Bone Carbine is a rare late-season blueprint that legitimately elevates the weapon it belongs to.
It isn't just cool-looking-it's competitive, smooth, and extremely fun.
