Season 6 introduced a brand new weapon, the TR-76 Geist, nerfed many of the top weapons such as the Kastov-762, the Chimera, the M13B, and the M13C, while giving some love taps to completely forgotten weapons such as the M16. All in all, this new season will shake up the META once more.

We’ve taken the changes into account and have compiled a list of the best assault rifles in Warzone right now.

5. ISO-Hemlock

My personal favorite ISO Hemlock had to make an appearance on this list, but do not fret, it is a justified pick. Even with the nerfs of Warzone Season 6, this weapon still performs alongside the best with laser-like accuracy and a comfy fire rate. The ISO Hemlock has a high time-to-kill despite the lower fire rate compared to other assault rifles.

Damage is the main issue with this weapon due to its lower fire rate, but it is a simple fix with certain attachments.

The best attachments and tuning are as follows:

  • Muzzle: Harbinger D20
    • Recoil smoothness +0.86oz
    • Bullet velocity +0.29in
  • Barrel: Fielder-T50
    • Recoil steadiness +0.18lb
    • Damage range +0.16in
  • Optic: SZ Recharge-DX
  • Underbarrel: FTAC Ripper 56
    • Recoil stabilization +0.62oz
    • Aiming idle stability +0.27in
  • Magazine: 45 Round Mag

4. M4

To some the M4’s addition to this list will be a surprise. Everyone’s first weapon is meant to be easy to use and perform well. However, not only does the M4 perform better than its counterparts, it completely blows them out of the water. With almost nonexistent recoil, high range, and high time-to-kill, the M4 has become a staple assault rifle for both new players and highly competitive ones.

The M4 needs only a little help to sculpt it into the beast that dominates mid-to-long range. With a barrel and muzzle that increase damage, a mag that allows squad-wipes, and an underbarrel that increases accuracy.

The best attachments and tuning are as follows:

  • Muzzle: Harbinger D20
    • Recoil smoothness +0.99oz
    • Bullet velocity +0.39in
  • Barrel: Hightower 20″ Barrel
    • Recoil steadiness +0.37lb
    • Damage range +0.28in
  • Underbarrel: FTAC Ripper
    • Recoil stabilization +0.33oz
    • Aiming idle stability +0.09in
  • Optic: Aim OP-V4
    • As always optics are a personal preference!
  • Magazine: 60 Round Mag

3. TR-76 Geist

The TR-76 Geist is the brand new addition to Warzone Season 6 and eagle-eyed fans will recognize this assault rifle as the age-old Tar-21. Thankfully, Activision has paid dividends to the pedigree of this weapon. It is a fantastic rifle, allowing you to gun down enemy operators from long range with ease. The Geist will be a perfect addition to anyone’s arsenal, but there are some bumps we have to iron out to let this beast shine.

Accuracy needs some work, its bouncy recoil is very similar to the Kastov-762, so fans of the AK will find a kindred spirit in the TR-76 Geist. But we will need to add attachments that improve its accuracy and range, even some increased damage.

The best attachments and tuning are as follows:

  • Muzzle: ZLR Talon 5
    • Recoil smoothness +0.86oz
    • Bullet velocity +0.71in
  • Barrel: Bruen Bridle Heavy
    • Recoil steadiness +0.31lb
    • Damage range +0.30in
  • Optic: Aim OP-V4
    • As always optics are personal preference!
  • Underbarrel: FTAC Ripper 56
    • Recoil stabilization +0.62oz
  • Magazine: 45 Round Mag

2. M13B

The M13B has maintained its strength moving into Season 6 and its popularity reaffirms that, for players, this weapon does it all. With high accuracy, the highest time-to-kill at long range for all assault rifles, and an easily manageable recoil pattern, this weapon deserves the second spot on this list.

To enable the M13B we have the usual attachments that bolster the assault rifle class, topped off with the 60 round mag and an optic that can be personal preference.

The best attachments and tuning are as follows:

  • Muzzle: Harbinger D20
    • Recoil stabilization +0.81oz
    • Bullet velocity +0.71in
  • Barrel: 14″ Bruen Echelon
    • Recoil steadiness +0.29lb
    • Damage range +0.28in
  • Optic: Aim OP-V4
  • Underbarrel: FTAC Ripper 56
    • Recoil stabilization +0.46oz
  • Mag: 60 Round Mag

1. Kastov-762

Nerf after nerf, season after season the Kastov-762 continues to climb to the top. Picked by 33% of players in a Warzone match, there’s a very good chance you’ve been killed by or killed with the Kastov in the last few months. Despite the nerfs introduced into Warzone Season 6, this weapon has continued its climb in popularity and shows no signs of stopping.

The Kastov-762 was hit by nerfs to its damage at all ranges, still it will remain an extremely high time-to-kill weapon at medium and long range. To help stabilize the sudden nerfs, we add attachments that increase damage across the board.

The best attachments and tuning are as follows:

  • Muzzle: ZLR Talon 5
    • Recoil smoothness +1.08oz
    • Bullet velocity +0.48in
  • Barrel: KAS-10 584mm Barrel
    • Recoil steadiness +0.39lb
    • Damage range +0.28in
  • Optic: Aim OP-V4
    • Some prefer the SZ Recharge-DX for its favorable bounce, as always its personal preference for the optic!
  • Ammunition: 7.62 High Velocity
    • Damage range +0.34g
    • Bullet velocity +5.23gr
  • Magazine: 40 Round Mag
