It functions very much the same as the standard anti-materiel rifle with increased damage, health and no spread but decreased critical hit damage bonus. It was intended to be used by an NCR sniper at Hoover Dam, but the cell containing the sniper was cut from the final game.
It will appear in the Pip-Boy as anti-materiel rifle, but it can not be stored or picked up if dropped; this is due to it being marked non-playable.
With better critical perk this weapon does less damage then the standard anti-materiel rifle as the critical damage bonus of this weapon is significantly less then that of the standard rifle.
