Warzone 2.0 provides deep customization options in Gunsmith. You can pick which attachments you want to boost specific attributes of your weapon, while the weapon tuning system allows you to tweak it even further.

However, with nine different attachment slots, and a maximum of five attachments on each weapon, you’ll have to decide which attachments to equip carefully.

Here’s a look at the best underbarrel attachments in the game and how to unlock them.



How to unlock the best underbarrel attachments in Warzone 2.0 and Modern Warfare 2

FSS Sharkfin 90

The FSS Sharkfin 90 is one of the rare attachments that come with no downsides. Instead, it effectively gives you a free boost to aiming idle stability, which refers to how much your reticle sways when aiming down sights.

If you have a free attachment slot and are unsure what else to equip, this is as good a choice as any.

How to unlock

  1. Level the M4 assault rifle to level 6.

Agent Grip

The Agent Grip is a strong pick for weapons like the Kastov-74U. It improves aiming idle stability and hip fire accuracy, while decreasing walking speed, an almost negligible price to pay.

How to unlock

  1. Reach military rank 31 to unlock the X12 handgun.
  2. Level the X12 to level 10 to unlock the X13 Auto.
  3. Level the X13 Auto to level 17.

Phase-3 Grip

The Phase-3 Grip boosts aiming idle stability, hip fire accuracy, and recoil stabilization, but it comes at the expense of walking speed and aim down sights speed.

However, the improvement to recoil stabilization is noticeable, particularly for weapons with heavy side-to-side sway.

How to unlock

  1. Reach military rank 23 to unlock the Kastov 762 assault rifle.
  2. Level the Kastov 762 to level 10 to unlock the Kastov 545 assault rifle.
  3. Level the Kastov 545 to level 13 to unlock the Kastov-74U assault rifle.
  4. Level the Kastov-74U to level 15 to unlock the Vaznev-9K SMG.
  5. Level the Vaznev-9K to level 9.

VX Pineapple

The VX Pineapple is another favorite for close-quarters weapons like the Kastov-74U or SMGs like the Lachmann Sub.

The improvements to hip fire accuracy and hip recoil control are excellent boons to have at close range, while the recoil steadiness bonus helps keep your shots on target. There is a small penalty in the form of slower hip walking speed and aim down sight speed, but it’s nothing too punishing.

How to unlock

  1. Level the M4 assault rifle to level 15 to unlock the 556 Icarus LMG.
  2. Level the 556 Icarus LMG to level 14.

Lockgrip Precision-40

The Lockgrip Precision-40 underbarrel is one of the best attachments for taming recoil on assault rifles. On the M4, it transforms the recoil pattern into a nearly straight line, virtually eliminating all side-to-side bounce.

How to unlock

  1. Reach military rank 16 to unlock the Lachmann-762 battle rifle.
  2. Level the Lachmann-762 to level 13 to unlock the Lachmann-556 assault rifle.
  3. Level the Lachmann-556 to level 12 to unlock the Lachmann Sub SMG.
  4. Level the Lachmann Sub to level 9.
