While under-barrel grenade launchers are a unique and specialized option in Escape from Tarkov, it’s essential to use the correct weapon attachments to equip them effectively. In addition to this, you also need to have suitable ammunition, which is also quite rare. This complete guide will provide you with all the necessary details on how to utilize the under-barrel grenade launcher, including the appropriate weapon preset and the ammo types to use in Escape from Tarkov.
How to Fire an Underbarrel Grenade Launcher in Escape from Tarkov
Once you acquire a weapon equipped with an under-barrel grenade launcher, it’s crucial to ensure you have the proper ammunition. This requirement applies to all firearms in Escape from Tarkov. After equipping the weapon featuring the under-barrel grenade launcher, you will need to switch between fire modes. If you placed the weapon in slot 2 or 3, you’ll have to press the corresponding number again to select the grenade launcher. For instance, if your M4A1 with the grenade launcher is mapped to 2, press 2 to pull out the M4A1, and press 2 again to switch to the grenade launcher.
To effectively fire the grenade launcher, load it with 40x46mm grenades. Here are the grenades available for use:
- 40x46mm M381 (HE) grenade (short range)
- 40x46mm M386 (HE) grenade (long range)
- 40x46mm M406 (HE) grenade (long range)
- 40x46mm M433 (HEDP) grenade (long range)
- 40x46mm M441 (HE) grenade (short range)
- 40x46mm M576 (MP-APERS) grenade (shotgun or bullet grains)
If you possess any of these grenade types in your rig or pockets, you can reload the grenade launcher with the available ammunition. Keep in mind that your character will prioritize grenades in your pockets before those in your rig. Therefore, if you prefer to use short-range grenades as your default choice, store them in your pockets to avoid needing to open your inventory for every swap. After successfully reloading the under-barrel grenade launcher, simply aim and fire.
