The weapon Mia Simon finds in the emergency shelter on Mount Zirilla. Fires metal bolts using highly pressurized air. This weapon had been chosen for the shelter due to fears that the thunderous report of a gunpowder rifle could cause an avalanche. There are a dozen or so ammo clips of fifty shots each and three gas cylinders goes in a slot on the bottom of the rifle's stock. The ammo clip locks into place in front of the trigger. The weapon fires bolts at a speed of Mach 3, but since the gun weighs over ten pounds with a clip in place, it has no kick.
