Assault rifle (Fallout 4)

	For an overview of assault rifles throughout the Fallout series, see assault rifle.

The assault rifle is a weapon in Fallout 4.

Background[]

A common sight in the Commonwealth, this assault rifle is used by higher-ranking raiders, Gunners officers and some super mutants.

Characteristics[]

This heavy assault rifle^[1], originally built for use by troops in power armor^[2], is a long, cylindrical-barrel design which appears to share more characteristics with light machine guns than any other firearm.^{[3][Non-game 1]} It features a side-fed magazine which houses 30 rounds of 5.56mm ammunition (can be upgraded to hold up to 80) and has select fire capability in either semi-automatic or fully automatic. It offers immense recoil control and remains very easy to keep under control, even when fully automatic.

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.

Locations[]

• Carried by many raiders, Gunners and super mutants once the player character reaches approximately level 25.
• Can be purchased from the following vendors:
  • KL-E-0 at Kill or Be Killed in Goodneighbor.
  • Arturo Rodriguez at Commonwealth Weaponry in Diamond City.
  • Myrna at Diamond City Surplus in Diamond City.
  • Cricket throughout the Commonwealth and at Bunker Hill.
  • Proctor Teagan on the Prydwen.
  • Ronnie Shaw at the Castle after Old Guns is completed.
• One can be found next to a door control terminal in the lowest level of the Massachusetts State House, outside the area where a mirelurk queen spawns.
• One can be found next to the Expert-locked terminal in the National Guard recruitment office on top of a container.
• One is carried by Captain Maria at Parsons State Insane Asylum.
• Another is carried by Edward Deegan, an employee of the Cabot family.
• One can be found inside the crashed Vertibird at the Coast Guard Pier (may require the use of explosives to get into reachable range).
• Occasionally carried by Triggermen at higher levels.
• One can be found in Kendall Hospital, on a table next to a lit lantern in the raider area above the deathclaw.
• Occasionally carried by Rust Devils.
• Carried and sold by Allen Lee in Far Harbor.
• Occasionally carried by trappers.
• Sold at the Nuka-Cade for 10,100 Nuka-Cade tickets (items rotate every couple of days).

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.
• 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.
• The first concept art of the weapon appears in The Art of Fallout 4 as a machine gun.^{[Non-game 1]}
• The ported barrel gives the same benefits as a short ported barrel, while the vented barrel is treated like a long ported barrel.
• Despite using 5.56mm ammunition, the suppressor attachment for the weapon has text which reads "CAL .50" printed on it.
• In reality, the term "assault rifle" refers to a rifle with the ability to shift between fire modes by a selector switch, while the in-game weapon is incapable of this and fire modes can only be changed by building separate receiver modifications.

Behind the scenes[]

• The assault rifle is referred to as meshes/weapons/machinegun/ in Nifskope and audio files refer to it as RifleIstvan, in reference to Bethesda art lead Istvan Pely.
• 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.
