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 assault rifle is a military assault rifle of Soviet origin that was in service during the early 21st century. Chambered for 5mm ammunition, it utilizes a 24-round magazine. The AK-112 was eventually considered aged and was scheduled to be replaced just prior to the Great War.

H&K G11


The H&K G11 is an advanced German assault rifle developed by Heckler & Koch. It has revolutionized assault weapon design and fires 4.7mm caseless, a cartridge consisting of a block of propellant with a bullet buried inside. The loading and feed mechanism is physically very complicated but exceptionally fast and reliable. Rounds are fed into the weapon from a magazine that lies above and parallel with the barrel.

The rounds are oriented vertically (at 90 degrees to the bore) and are fed downwards into the rotary chamber so that they can be rotated 90 degrees for firing. Because the H&K G11 uses caseless ammunition, there are no extraction and ejection steps. The resultant weight and space savings allow the H&K G11 to have a very high-capacity, 50-round magazine.

H&K G11E


The H&K G11E is a new version of the standard H&K G11, equipped with a low-light scope, an extended barrel and an electronic regulator on the left side. It also has a better firepower and rate of fire.

XL70E3


The XL70E3 was an experimental assault rifle developed in the late 21st century just before the Great War. It is equipped with a scope, fires 5mm ammunition and utilizes a 20-round magazine. Manufactured, primarily, from high-strength polymers, the XL70E3 is almost indestructible. It is light, fast firing, accurate, and can be broken down without the use of tools.

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 Washington, D.C., was the R91 full-auto urban assault rifle. The R91 assault 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 Great War, the R91 is readily available for those willing to search around this area. Although nearly two centuries of scavenging has reduced the numbers of working units, the R91 remains a favorite of slavers, raiders, and mercenaries in the Capital Wasteland.

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 and utilizes a 24-round magazine. 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.

Infiltrator


 The Infiltrator is a silenced and scoped assault rifle. Its appearance consists of a black paint finish, a scope, and is basically a shortened and stock-less variant of the R91 assault rifle that was standard-issue in the United States Armed Forces at the time of the Great War. Based on its name, it was probably created to be used for special operations groups. The Infiltrator fires 5.56mm round and utilizes a 24-round magazine.

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 weapons 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.

Unnamed assault carbine


This assault carbine is a compact automatic rifle with a high rate of fire and a comparatively low spread. It sports a very compact size, fires 5mm round and utilizes a 24-round magazine. It is very accurate for an automatic weapon and highly effective against medium or heavily armored targets.

Unnamed assault rifle


This assault rifle is a long, cylindrical-barrel design which does not resemble any past version. It features a side-fed magazine which houses 30 5.56mm rounds (can be upgraded to hold up to 80), and is available in either semi-automatic or fully automatic variations. It offers immense recoil control and remains very easy to keep under control, even when fully automatic.

AK-47


The AK-47 is a selective-fire, gas-operated assault rifle developed in 1944 by Izhmash. It fires 7.62mm and utilizes a 24-round magazine. The main advantages of the AK-47 is its simple design, fairly compact size, inexpensive to manufacture, and easy to clean and maintain. The large gas piston and tapered cartridge case design allow the gun to endure large amounts of foreign matter and fouling without failing to cycle.

The bore and chamber, as well as the gas piston and the interior of the gas cylinder, are chromium-plated, dramatically increasing the life of these parts by resisting corrosion and wear. As each bullet travels through the barrel, a portion of the gases expanding behind it is diverted into the gas tube above the barrel, where it impacts the gas piston. The piston, in turn, is driven backward, pushing the bolt carrier, which causes the bolt to move backwards, ejecting the spent round, and chambering a new round when the recoil spring pushes it back. Its reliability, ruggedness and accuracy have earned it the reputation of being the best assault rifle ever made.

M16A1


The M16A1 is an assault rifle developed in 1967 by Colt. The intention was to create an innovative firearm design that incorporated many of the new materials being used in aerospace design. The M16A1 is composed of durable aluminum alloy and hearty plastic, fires 5.56mm with a 24-round magazine. The M16A1 also has distinctive sights, consisting of a simple round screw-in front sight post. Through the years, it remained a very reliable assault rifle and was the standard rifle used by the US Army from 1970 and during the middle part of the 20th century, succeeding the M-14.

Ruger AC556F

The Ruger AC556F, created in the 1970s by Ruger, is a development of the Ruger Mini-14, an old assault rifle originally used only by police forces. The Ruger AC556F replaced it and was marketed for military and law enforcement use. It has a reflex scope, fires 5.56mm with a 20-round magazine. As a heavy-duty automatic weapon, the Ruger AC556F was designed to for rough handling in the militaristic environments of combat zones or in pulling security duties.

Steyr AUG


The Steyr AUG is a bullpup assault rifle created in 1977 by Steyr Mannlicher. It's a selective fire weapon with a conventional gas piston operated action that fires from a closed bolt. It uses 5.56mm with a 40-round magazine. Designed as a rifle that could be quickly adapted to a wide variety of roles, the Steyr AUG is a modular configuration rifle that employs a high level of polymer and advanced alloy components, consisting of six main assemblies: the barrel, receiver with integrated telescopic sight, bolt and carrier, trigger mechanism, stock and magazine.

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.
