R91 Assault Rifle

The Fallout 3 basic Assault Rifle is the R91.


The R91 is a general purpose automatic firearm, effective from short to medium range. The rifle is also less effective in point-blank range, where the barrel sometimes clips through the target or level geometry (see Bug's section). Nevertheless, it remains a light-weight, hard-hitting weapon for low to mid-level Small Guns users.

Condition degrades at a moderate rate. Poor condition Assault Rifles are sold by many vendors across the Wasteland, and are found in Raider-occupied camps, buildings, and Metro tunnels.

The basic Assault Rifle differs from the Chinese Assault Rifle: the latter does more damage (44 DPS compared to the R91 Assault Rifle's 32 DPS), is more durable, but is also scarce. Spread and magazine capacity is identical.

Ammunition is relatively abundant. See 5.56mm page.

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 standard issue for the US Army and National Guard during the urban pacification operations and combat. Fortunately for our purposes, the National Guard had been fully deployed around the DC area during the time of the war. As a result, 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.

Like any firearm, the R91's effectiveness and accuracy can suffer without regular maintenance.


  • In Fallout 3, this weapon is called simply "Assault Rifle". However, this article's title uses its full name to distinguish it from the AK-112 Assault Rifle from Fallout and Fallout 2. The rifle is almost an exact visual duplicate of the Spanish CETME Modelo C. but chambered for 5.56mm.
  • This weapon, along with the Chinese Assault rifle, appears in the Operation: Anchorage combat simulator, with a pristine look as opposed to the Wasteland's weathered and beaten finish.
  • There are some locations in which 4-7 Assault Rifles can be found, all in (very) bad condition:


  • The Assault Rifle can clip through targets or level geometry in V.A.T.S. This results in all shots missing or being absorbed by geometry, even when the muzzle protrudes past the obstruction. Against point-blank targets in V.A.T.S., the rifle sometimes inflicts minimal damage. (confirmed all platforms)
