Call of Duty: Black Ops 7 Season 3 kicks off one of the biggest seasons yet, with the arrival of some old classic Multiplayer maps like Plaza, a new battleground for Battle Royale with Avalon, and a host of new weapons. One of the new weapons available for Season 3 is the MK35 ISR, an Assault Rifle that is already proving to be a meta contender. Here is the best meta loadout for the MK35 ISR in both Black Ops 7 and Warzone.

Black Ops 7 and Warzone’s Ranked Play Season 3 has kicked off, bringing new rewards for players to unlock. Here is every Ranked Play Season 3 Reward.
The MK35 ISR is already one of the top Assault Rifles to use in Black Ops 7 Multiplayer, and our suggested build for the weapon is easily one of the top meta choices. This build boasts very little recoil, remaining accurate all the way up to the 50-meter range with minimal horizontal deviation and only a small amount of controllable vertical recoil.
The TTK of the weapon itself is relatively fast, and with this build, that fast TTK is extended well beyond the 50-meter mark. This setup serves as one of the best and easiest Assault Rifle builds to use for beginners and veterans alike. However, it does use the integrated Suppressed Barrel, which requires players to reach at least Prestige 1. In the meantime, players can use a standard Suppressor or Long Barrel until they unlock it.

Next up is a meta build specifically for Warzone. While damage range is not increased with this build, bullet velocity has been boosted from the standard 910 m/s to 1,255.8 m/s. This drastically reduces the need to lead your shots at long range, making it an excellent choice for the long-range meta.
To say this build has zero recoil is an understatement. The recoil is so minimal that players will barely need to pull down or adjust for horizontal shake. The only major downsides are that movement speed and aim-down-sight speed do take a hit. However, for a weapon that strictly handles long-range gunfights, you can always carry an SMG in your secondary slot to deal with enemies up close.
