The R91 assault rifle is a two-handed small gun in Fallout 3.[1]


Assault rifle expanded

The R91 is a general-purpose automatic firearm, effective from short to medium range. However, the high spread and low damage per shot greatly reduce its effectiveness against targets at a longer range or hard targets like giant radscorpions. Nevertheless, it remains a lightweight, 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 often found in raider camps, buildings, and Metro tunnels.


The assault rifle can fire a total of 1250 rounds, the equivalent of 53 reloads, from full condition before breaking.


  • Infiltrator The Pitt (add-on) - A scoped, silenced, and stockless version of the R-91 assault rifle. It is comparable to the silenced 10mm pistol in that it sacrifices firepower to reduce noise.
  • Perforator The Pitt (add-on) - A unique version of the Infiltrator, it has the slowest rate of fire of any assault weapon.
  • Sim version Operation: Anchorage (add-on) - A sim-only version of the weapon that differs only in health (essentially non-degrading). It features a cleaner, less-battered texture with fresh wood and darker metal areas than its wasteland counterpart. Available via the assault package in the deployment terminal.
  • Wanda - A unique R-91 assault rifle that was cut from the final game.
  • Alloy steel assault rifle Operation: Anchorage (add-on)- A variant named "alloy steel assault rifle" can be found in the data files for Operation: Anchorage. It uses the Anchorage-specific texture for the weapon, but aside from name and appearance is identical to the standard R-91 assault rifle. It is likely the weapon was intended to be placed in the armory with other "wasteland" versions of weapons found in the Anchorage sim, most of which were cut from the final version of the add-on; as such the weapon can only be accessed through the use of console commands.

Behind the scenes


PCPC Playstation 3Playstation 3 Xbox 360Xbox 360 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.[verified]
