Assault Rifle (Fallout 4)

The Assault Rifle, also known as the M199 Assault Rifle, is a weapon in Fallout 4.

Background
The M199 Assault Rifle was described as the "most well-recognized weapon in the modern U.S. Military arsenal" before the Great War. It was known to make a distinctive sound when ejecting a spent shell, leading it to be nicknamed "the Backtalker." It was displayed as part of a museum exhibit on loan from the International Ordnance Museum at the Museum of Technology in Washington D.C.

Characteristics
The Assault Rifle starts off semi-automatic but can be modded or found with an automatic receiver at the expense of significant damage reduction. A regular, semi-automatic assault rifle with all of the highest level mods equipped deals around 99 damage with 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 high accuracy even when fitted with an automatic receiver. Any modification requires investment in the Gun Nut perk, and some investment in the Science! perk for its advanced optical sights. At higher levels, modified assault rifles may appear as loot.

Behind the scenes

 * The Assault Rifle is referred to as meshes/weapons/machinegun/ in Nifskope and audio files refer to it as RifleIstvan . Istvan Pely is credited as Lead Artist in Fallout 4.
 * Creation Club author George Appleby described his experience with giving the Assault Rifle the M199 designation for the U.S. Army, Brotherhood of Steel, Institute, and Vault-Tec paints. The M199 was mentioned in Fallout 3 as the "official infantry weapon of the U.S. Army", which Appleby applied the Assault Rifle, stating that it "seemed to make sense in [his] mind."
