Call of Duty: Warzone 2 is fresh off of its release and somehow fans have already found arguably the best AR in the Kastov-74U. If you want to take full advantage of its capabilities, then take a look at our attachment guide.

Considered one of the best weapons in both our Assault Rifle and Weapon Tier Lists, the Kastov-74U is most noteworthy for its ability to work as both an SMG and AR. This makes it a deadly weapon at close-to-mid range. It's so deadly that many professional players have GA'd or made a gentleman's agreement to forgo it during competitions.

Warzone 2 Kastov-74U Build: Best Attachments to Use

In order to take this weapon to the next level, it's important to focus on attachments that boost its Assault Rifle capabilities. This is key since the Kastov-74U already plays like an SMG. That means equipping attachments that boost range, accuracy, and reduce recoil should be the focus of your build.

The following attachments will do everything that we've covered and will give you a Kastov-74U build that'll leave your opponents speechless.

  • Muzzle: Echoless-80
  • Laser: Schlager PEQ Box IV
  • Stock: FT TAC-Elite Stock
  • Underbarrel: FSS Sharkfin 90
  • Magazine: 45-Round Mag

The Echoless-80 muzzle is important as it masks you from the mini-map, while extending the Kastov-74U's range and damage. Since this muzzle brings down your ADS speed, the Schlager PEQ Box IV should be the next attachment to equip. This laser provides great ADS speed and can more than make up for the Echoless-80.

The FT TAC-Elite Stock is great for its recoil reduction and should make mobility with this weapon more seamless for users. To boost your accuracy even further, we recommend adding on the FSS Sharkfin as your underbarrel. Cap this build off with a 45-Round Mag to give you enough ammunition to not have to worry about getting eliminated mid-reload.

Players that have maxed out the Kastov-74U can also tune these listed attachments. The following tuning measurements will give the Kastov-74U attachments that extra push toward eliteness.


  • Aim Down Sight Speed: -1.40 oz
  • Aiming Idle Stability: -1.00 in

FSS Sharkfin 90

  • Recoil Stabilization: +0.62 oz
  • Aiming Idle Stability: +0.40 in

FT TAC- Elite Stock

  • Aim Down Sight Speed: -4.00 oz
  • Aiming Idle Stability: +2.40 in

The listed tuning measurements above will make sure that the Kastov-74U is even more accurate and responsive. In the end, this build will give users a weapon that can effectively double as an SMG and AR during matches. Pairing this weapon with a Sniper Rifle to cover long distances will make you a well-rounded threat on the battlefield.
