The weapon's frame is similar in appearance to that of a grenade launcher. The holorifle is a scoped, pump-action energy based weapon.
The construction of the holorifle enabled him to circumvent the security of the Sierra Madre, which normally confiscates items with even trace amounts of contamination and returns them to the owner's home. He used a standard grenade launcher as the template, modifying it with a hologram emitter and drawing power from microfusion cells loaded into the grenade tube. The holorifle, along with other model types, was constructed by Father Elijah, utilizing technology that he had obtained from the Big Empty and fashioned from the holograms in the Sierra Madre.
