The auto grenade launcher is an explosive heavy gun in Fallout 76.

Background

The auto grenade launcher is a fully automatic 40mm explosive heavy weapon found in Appalachia. Using 12-round belts of grenades held in a belt box on the left side of the weapon, the auto grenade launcher is capable of rapidly firing large quantities of high explosive rounds at enemies.

Characteristics

The auto grenade launcher is a powerful, automatic explosive weapon firing belt-fed 40mm grenades. Delivering a high volume of explosive ordnance at the range, it is difficult to ignore, especially when taking into account the damage bonuses from using the right perk cards. It does not benefit from Heavy Gunner due to the perk not accounting for explosive heavy weapons. However, it does benefit from Demolition Expert.

When fired in VATS, the grenades home in on their target, guaranteeing a hit every time (except in very rare circumstances), regardless of the actual chance to hit the target that is shown, assuming that it is not zero. It is also very awkward to aim and fire normally (with one reason being its lack of iron sights to aim with in first-person view); because of this, this weapon greatly benefits from VATS-related legendary perks. In addition, the Two Shot legendary effect effectively doubles the damage of the gun, making it even more powerful.

This weapon cannot spawn or be rolled with the Quad, or Explosive legendary effects.

Notes

While the auto grenade launcher has very similar handling and reloading animations as the .50 cal machine gun in first-person view, the player will reload it differently in third-person.
