Assault Rifle (Fallout 4)

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. 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.

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.
 * The "U.S. Army weapon paints" Creation Club pack, created by community modder Skidabaa in collaboration with Bethesda, identifies 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 the U.S. Army paint is applied.
