Holorifle

The  is a weapon in the Fallout: New Vegas add on Dead Money

About
The holorifle is an energy weapon created by Father Elijah in the DLC Dead Money. You receive the gun upon entering Sierra Madre. It is a scoped, pump-action weapon that works very well against the Ghost People. It does a special "Holorifle Damage" effect. The Weapon uses Microfusion cells as ammo but is unique in the sense that its projectile is neither plasma, laser, gauss, flame, tesla, or pulse. Loading takes place via an under-barrel tubular magazine, where up to 4 Microfusion cells are loaded. It's name hints that it may use the same weapon technology that the Sierra Madre holograms do.

The gun appears to be an Energy weapon conversion of the Grenade launcher.

Bugs

 * Occasionally, The weapon will refuse to fire in VATS, and the player will be stuck watching enemies attack him unable to do anything.
 * The weapon will enter a never ending reload cycle when switching ammo types.
 * The weapon will miss at contact range.(verified)
 * While carrying the weapon, the Courier's arms will cycle down below the screen, then appear above it and settle back into place. This is purely cosmetic, and neither causes crashes or interferes with firing the weapon. (This happens for me on almost every weapon-360)
 * Just after reloading, the weapon will cause your character to move slowly (almost as if your legs are crippled) this bug sorts out in a matter of seconds, but is very annoying.
 * Can be continuously repair with weapon repair kits to infinitely increase the value.
 * The weapon may sometimes glitch and will not take any damage no matter how many shots are fired once all the upgrades are installed, which is good because the weapon is not cheap to repair from an NPC and making weapon repair kits can be time consuming.
