The assault rifle is a weapon in Fallout 4.

Background

Fed from a side-mounted magazine, this assault rifle has anti-aircraft style sights and interchangeable barrels and magazines.[1] It includes a charging handle on the right fashioned out of wood. A common sight in the Commonwealth, this assault rifle is used by higher-ranking raiders, Gunners officers and some super mutants.

Characteristics

The assault rifle starts off semi-automatic but can be modded or found with an automatic receiver at the expense of a hefty damage reduction. A regular, semi-automatic assault rifle with all of the highest level mods equipped deals around 99 damage assuming the Sole Survivor has all of the Rifleman perks. This damage can be increased by finding a legendary variant with the mighty/powerful prefix. The weapon is heavy for an assault rifle, weighing 13.1 pounds (5.9 kg) unmodified with a short barrel, and when modified can weigh as much as 26 pounds.

The assault rifle has low recoil and good accuracy (even when fitted with an automatic receiver), both of which are excellent handling traits for sustained automatic fire, though the weapon can burn through ammo rapidly; this can be compounded by the relative scarcity of 5.56mm rounds at lower levels that can be looted from enemies without the Scrounger perk.

Any modification requires heavy investment in the Gun Nut perk, and some investment in the Science! perk for its advanced optical sights. However, after reaching a high level, modified assault rifles may appear as loot.

Notes

  • The assault rifle is the only gun in the base game that utilizes 5.56 ammunition.
  • When used for sneak attacks in V.A.T.S., the assault rifle fires only one shot per action even when upgraded with an automatic receiver, a trait that goes a long way towards making the most efficient use of its scarce ammunition type. Outside of sneak mode, it will fire several shots per burst just like any other automatic weapon.
  • In the game files, it is called "MachineGun," while "AssaultRifle" refers to a cut version of the Chinese assault rifle. It is also known as the "Machine Gun" by its concept art.
    • The icon used in the "Favorite items" menu resembles a Chinese assault rifle.
  • The texture for the suppressor shows that the assault rifle was once intended to be a .50 caliber weapon.
  • After reloading, the player character does not cock the gun with the charging handle.
  • When carried by companions in power armor, their walking animation may change, causing the ground to rumble while they walk; as if they had jumped and landed from a height.

Behind the scenes

  • The assault rifle is referred to as a machine gun in its Nifskope models, stemming from the fact that, during Fallout 4's development, the assault rifle was one of the first weapons created, and was originally called a "machine gun" before the weapon crafting system was developed.[1][2]
  • The "Army, Atom Cats, Gunners and Vault-Tec Weapon Paint Job" and "Brotherhood of Steel, Institute, Railroad, Minutemen Weapon Paint Job" Creation Club bundles, created by community modder Skidabaa in collaboration with Bethesda, identify this weapon as the M199 assault rifle mentioned in Fallout 3. The name can be seen when the "drum magazine" modification is applied to the weapon while one of the relevant paints is applied.

    The first gun made for the game. We mainly wanted something beefy that would look right in the power armor's oversized hands. It was also a chance to explore modification and customization. We designed it to allow interchangeable barrels and magazines. At this early stage of the project, we didn't plan on giving the player too many options, but we'd go on to develop a deeper and more flexible system. This particular gun design would later become the assault rifle."
