R91 Assault Rifle

The R91 Urban Assault Rifle is a fully-automatic assault rifle chambered in 5.56x45mm NATO. It is a member of the R Series of combat rifles produced by civilian manufacturer Stent Security Solutions.

The R91 was issued to the United States Armed Forces during urban pacification and urban combat operations. Since the National Guard had been fully deployed in the days leading up to the Great War, the R91 is relatively common in the ruins of major urban areas. Although two centuries of scavenging has reduced the numbers of working units, the R91 remains a favorite of slavers, raiders, and mercenaries across the wasteland.
