Black Ops 7 MXR 17 Assault Rifle SMG Class Setup Build Guides

Since the start of Black Ops 7, we have been trying to see how well we could turn Assault Rifles into SMGs, and the results have been amazing. If you've been following our guides, you probably already know that we have turned the M15 Mod Zero, AK-27, Peacekeeper, and Maddox into monsters for close-quarters. But the MXR 17? This one is different.

 

Black Ops 7 MXR 17 Assault Rifle SMG Class Setup Build Guides

 

We are not looking to change the stats, but to change the weapon's identity. By downgrading it and adding only 5 attachments, we allow the MXR 17 to reach a level of mobility and handling that is comparable to genuine SMGs, while preserving the having the full strength of an Assault Rifle. If you want to run around and nuke the opposition with other frustrations, this is the loadout you need to equip immediately.



The 5-Attachment Godlike Build

We generally recommend that you fill all of the weapon's eight slots with attachments. For this unique MXR 17 conversion, you want to have only five and it should still give you a lot of the hybrid dominance.

 

 

Here is the breakdown of the exact components that make this loadout work.

Attachment Slot Component Name Primary Benefit Why Use It
MuzzleRed Well 90 Compensator Gun Kick & Recoil Control The MXR 17 has a weird native kick. Smoothing it is a much better option allowing for your shots to be laser focused.
Barrel15-in Wraith Barrel ADS & Sprint to Fire Speed This is the engine of the build. It drastically imrpoves handling giving the gun that snappy SMG feel.
UnderbarrelEAM Steady 90 Grip Movement Speed & Horizontal Control Allows drifting to be unpredictable while keeping the the recoil pattern stuck to the center.
Magazine25 Round Flip Mag Reload Speed Perfect for aggro. The Twin Pack'style lets you get right back into the action fast.
StockGrievous Covenant Stock Mobility & Strafe Speed Skipping the rear grip to focus purely on strafe speed makes you a harder target to hit.

 

Deep Dive: Why This Combination Works

1. Handling the Recoil (Muzzle & Underbarrel)

The MXR 17 has some very strong recoil. Using the Red Well 90 Compensator and the EAM Steady 90 Grip will fix will some recoil, but will also center the gun and make the recoil easier to control. This makes it easier to aim and control while sprinting and shooting.

 

2. Speed (Barrel & Stock)

This feels like an SMG because of the 15-in Wraith Barrel. This increases your Aim Down Sight (ADS) speed and your Sprint-to-Fire speed. Combine the barrel with the Grievous Covenant Stock for insane strafing, allowing you to fire and strafe to cover quicker than the enemy can track. In addition, this barrel visually makes the weapon look sleeker, representing its close-quarters role.

 

3. Uptime Efficiency (Magazine)

It may sound crazy, but 25 rounds is sometimes more than enough, especially when paired with the Flip Mag. You can reload on the fly with insane efficiency. You can stay more mobile than with a heavier extended mag because this option is a lot more streamlined. Whether you're spawn trapping or pushing a hard point, that millisecond reload efficiency will almost always save you even more than a few extra rounds.

 

The Complete Loadout Strategy

A gun is only as good as the soldier that wields it. This insane aggressive playstyle will only work to its fullest potential when you have the right perks to complement the speed of the weapon.

 

 

Wildcard:Perk Greed (allows you to have more perks, vital for staying alive).

Field Upgrade:Mute Field.

Tactical Note:

This is a must for players dedicated to high streaks. It gives you Cold Blooded, Ghost, and Ninja. The best thing about it is that every kill you get makes it last even longer. If you're chaining kills, you're pretty much invisible to the other team the whole game.

Tactical/Lethal:

Stim Shot for instant health and Semtex with high explosive density to clear out campers.

Perk Setup:

We recommend running Lightweight, Scavenger, and Looter. This combination activates Enforcer, giving you speed and health regen boosts after Defeats. In the Greed slot, Flak Jacket is a lifesaver against random grenade spam.

 

Gameplay Tips

So, you have built the class. How do you actually play it?

 

Be Aggressive

Do not sit back. This build relies on the Wraith Barrel's sprint-to-fire speed. You should be running and pushing the enemy spawn. The weapon handles quickly, so even if you're caught sprinting, you can snap onto the target.

 

The Reload Cancel Flow

With the Flip Mag, you never need to backtrack to reload. If you Defeat an enemy and have 5 bullets left, slide to the next cover, then reload. The animation is so quick that you will be ready to fire before you even stop sliding.

 

Spawn Trapping

Since you are using Mute Field, you should be out of sight from the enemies radar. Use this to try and go behind the enemy's position. Once you are at the enemy's spawn, you can begin eliminating enemies with the MXR 17's high damage. The set up shown to you has dropped several nukes, simply due to the enemy not being able to figure out where the bullets are coming from.

 

Frequently Asked Questions (FAQ)

Q: Can I put a sight on this build?

A: Sure, but we prefer using the MXR 17's iron sights. The MXR 17's iron sights are good enough for close and medium range combats and will save you an attachment slot. If you really need to add an optic, you can get rid of the stock, but you'll lose a lot of that important strafe speed.

 

Q: Does this build work for far range?

A: Surprisingly, yes it does. But, keep it mind this build was intended to be an SMG. The range will be attributted to the MXR 17's recoil being controlled. But, damage will drop from distance. It will work best for close and medium range and there is not much else on the he market that will out perform this build.

 

Q: Why is there a limit of 5 attachments instead of 8?

A: More attachments are not always better. Sometimes extra attachments bring on extra penalties like slower aim down sights. The 5 attachments listed are a perfect combination of speed and control without any bloat that slows you down.

 

Final Thoughts

Hands down, one of the most enjoyable and effective builds so far in Black Ops 7 is the MXR 17 conversion. It combines the sheer stopping power of an Assault Rifle with the excitement of an SMG.

If you want to change up your playstyle, improve your overall score, or frustrate the enemy team with your speed, use this loadout before the balance patch hits. Now that we have focused on the MXR, tell us what you want us to convert next. Should we attempt to convert an SMG into a long-range beamer? The experiments continue.
