Assault rifle

An assault rifle is a selective fire rifle that uses an intermediate cartridge and a detachable magazine. Assault rifles are the standard infantry weapons in most modern armies. Assault rifles are categorized in between light machine guns, which are intended more for sustained automatic fire in a light support role, and submachine guns, which fire a pistol cartridge rather than a rifle cartridge.

AK-112 assault rifle


 The AK-112 was an old military model of supposedly Soviet origin that was in service during the early 21st century. Chambered for 5mm ammunition, it utilizes a 24-round magazine and is capable of firing single-shot or in bursts. This weapon was eventually considered aged and was scheduled to be replaced just prior to the Great War.

H&K G11


This gun revolutionized assault weapon design. The weapon fires a caseless cartridge consisting of a block of propellant with a bullet buried inside. The resultant weight and space savings allow this weapon to have a very high magazine capacity. While the 4.7mm caseless rounds are moderately rare, the G11 is one of the best SMGs in Fallout 2.

H&K G11E


A variant of the H&K G11, the E variant is equipped with a low-light scope and a suppressor. It also fires more rounds in a burst and deals more damage with each individual round.

R91 assault rifle


 The R Series of combat assault rifles was used reliably following the discontinuation of the M Series in the early 21st century. The R series, produced by civilian manufacturer Stent Security Solutions, was made in many models and variations. The variation most common to the DC Wasteland is the R91 full-auto urban assault rifle.

This rifle was issued in the United States Armed Forces during the urban pacification operations and combat. Since the National Guard had been fully deployed around the DC area during the time of the war, the R91 is readily available for those willing to search. Although nearly two centuries of scavenging has reduced the numbers of working units, the R91 remains a favorite of slavers, raiders, and mercenaries. This rifle can often be obtained from legitimate traders and arms dealers.

Infiltrator


 The Infiltrator is a silenced and scoped 5.56mm assault rifle. Since it has a black color, it is scoped, more shortened and stockless than the R91 assault rifle mostly issued in the United States Armed Forces and based on its name, it was probably created to be use for special operations. Despite its scope, the Infiltrator still suffers from the typical inaccuracy of assault rifles at long-range combat, limiting its suitability only for short and middle-range combat. It is one of the favorite weapon of the Pitt raiders in The Pitt and in 2281, Mick is known for having one in his collection of his secret arsenal in Freeside. 

Perforator
 The Perforator is an improved Infiltrator, with better firepower, lower rate of fire and better accuracy over longer distance. It was in possession of Everett in The Pitt in 2277. It has the same appearance as the standard Infiltrator. 

Type 93 Chinese assault rifle


 The Type 93 Chinese assault rifle was designed and manufactured by a Chinese industrial conglomerate for the People's Liberation Army during the Resource Wars, for the purpose of equipping the Chinese infiltrators and American fifth-columnists. To this end, it was chambered for the abundant 5.56mm round. This model of assault rifle does slightly more damage than its American made counterpart.

Thousands of these weapons were smuggled into the US for use by Chinese operatives and sympathizers on the East Coast, and many remain functional even two hundred years after the Great War. These rifles are also proven to be ready for manufacturing in post-war conditions.

M199 assault rifle
Perhaps the most well-recognized weapon in the pre-War U.S. Military arsenal, the M199 earned its nickname "The Backtalker" from the unusual report the firing mechanism makes as it ejects a spent shell. Firing standard 5.56mm rounds, the M199 was the official infantry weapon of the U.S. Army.

Unnamed assault carbine


This 5mm assault carbine sports a very compact size compared to the R91, which was the United States' primary combat rifle.

FN FAL


This rifle has been more widely used by armed forces than any other rifle in history. It's a reliable assault weapon for any terrain or tactical situation.

XL70E3


This was an experimental weapon at the time of the war. Manufactured, primarily, from high-strength polymers, the weapon is almost indestructible. It's light, fast firing, accurate, and can be broken down without the use of tools.

AKA-47

AK-47


The AK-47 and its derivatives formed the mainstay of the Soviet Armies. Its reliability, ruggedness and accuracy have earned it the reputation of being the best assault rifle ever made.

M16A1


The M16A1 was the chief rifle used by the United States Marines during the start of the 21st century, and was later to be replaced by the M4 carbine. Composed of durable aluminum alloy and hearty plastic.

Ruger AC556F


The Ruger AC556F is a development of the Ruger Mini 14, a 5.56 mm assault rifle originally used only by police forces, but also popular on the open market. A large magazine and full auto fire makes this weapon a real crowd pleaser.
