The M79 grenade launcher is an explosive heavy gun in Fallout 76.

Background

One of the earliest United States grenade launcher designs, built around the 40mm grenade. Utilizing the High-Low propulsion system, the M79 allows the operator to deliver high explosive rounds at a range of hundreds of meters, while its rugged design, consisting of just five major parts, a receiver, fore-end, barrel, sight, and stock, offers excellent reliability. The one drawback is that the grenade launcher is single-shot only, reducing its rate of fire and precluding a sustained volume of fire. However, it is quite compact, especially with the stock sawed off, while the straightforward optics, consisting of a fixed blade sight on the front and a folding leaf sight on the rear, enable accurate fire with just pointing and shooting. These qualities kept it in use well into the late 21st century.[2][3]

Characteristics

M79 expanded

A single shot, break-action, 40mm grenade launcher. When fired, the grenade is propelled in an arc, rather than laterally, meaning it's best to aim at the ground below the target rather than directly at the target for more consistent hits.

Behind the scenes

In an earlier patch, the M79 was considered both a shotgun and an explosive weapon. That meant that the M79 could benefit from both shotgun damage perks and the explosives damage perk cards. This has been corrected in patches 1.0.3.10[4] and 1.0.4.13.[5]
