Assault Rifle (Fallout 3)

The Fallout 3 basic Assault Rifle is the R91.

Characteristics
It is useful at short to medium range where short aimed bursts can quickly kill enemies. The rifle also excels at close range where full automatic fire can kill all but the toughest opponents. Apart from the appearance of the guns, the only difference between the assault rifle and the Chinese Assault Rifle is that the latter does more damage (44 DPS compared to the assault rifle's 32 DPS). The Chinese Assault Rifle is also more scarce.

Weapon Information Database Research File
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 National Guard during the urban pacification operations. 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 and Raiders. 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.

Possible Designation M199
When you enter the Museum of Technology, the second case on the right has a plaque with the following text:

"Perhaps the most well-recognized weapon in the modern 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 casing. Firing standard 5.56x45mm rounds, the M199 is still the official infantry weapon of the U.S. Army."

On loan from the International Ordanance Museum, these cases display the various types of weapons and ammunition used by the military in the past conflicts all over the globe.
