One of the newer additions to both Warzone Mobile and Modern Warfare III, the Rival-9 can work well especially as a maneuverable SMG that can easily be handled both as a frontline support or a backup piece.

What are some of the best attachments for this fast-firing and easy-to-handle SMG? We tested it out during both the Limited Release and the current play and found this build to work!

UNDERBARREL: Bruen Tactical Vertical Grip (unlocked by leveling the MCW to Level 9)

This grip helps capitalize on the potential of the Rival-9 to become a hip fire beast by stabilizing the weapon’s gun kick and also reducing a bit of the hipfire spread.

 

BARREL: Rival-C Clearshot (unlocked at Level 4)

This longer barrel essentially makes your Rival-9 a pistol-caliber automatic carbine capable of ADS or hip fire engagements at close-to-mid range.

MUZZLE: Sonic Suppressor S (unlocked by leveling the WSP-9 at Level 24)

The SMG version of the Sonic Suppressor functions very much like its bigger brothers by greatly increasing bullet velocity and adding a small damage range increase, allowing you to engage enemies at better distances. 

MAGAZINE: 50 Round Drum (unlocked at Level 18)

The Rival-9’s fire rate can easily shred opponents, especially at close range. This SMG’s fast fire rate will leave you hungry for more ammunition to bring down opponents in intense, close quarter gunfights. Use the 50-round drum mag attachment to make the most out of your Rival-9’s flexible potential!

LASER: Point G3P-04 (unlocked by leveling up the Expedite 12 shotgun to Level 11)

The Point G3P-04 is a green hipfire-centered laser which can also help reduce the overall sprint to fire time of your Rival-9. This allows your build to be used effectively whenever you’re aiming down sights or firing from the hip at close quarters.

 

OPTIONAL REPLACEMENTS:

LASER: VLK LZR 7mw (unlocked by leveling the STB 556 to level 5)

The VLK LZR 7mw ensures that your Rival-9 can have a faster ADS and sprint to fire speed while also providing much-needed aiming stability.

 

AMMUNITION: 9mm High Grain Rounds (unlocked by leveling up the AMR9 to Level 29)

9mm High Grain Rounds can be used to further increase the potency of your Rival-9 by adding a range and damage buff per shot, at the cost of some recoil control which the Bruen Tactical Vertical Grip can mitigate. 

These attachments can help you utilize a flexible, easy-to-use SMG which can definitely help you clean house!
