Radium rifle (Far Harbor)

The radium rifle is a weapon in the Fallout 4 add-on Far Harbor.

Gameplay
The radium rifle has been modified to deal radiation damage. Similar to a combat rifle, differences being requiring higher levels of the Gun Nut and Science! perks, and the inability to attach a recon scope or a .308 receiver.

Variants

 * Kiloton radium rifle - A unique variant with the Explosive Legendary effect, which can be obtained from Kane in the Nucleus.
 * Radical Conversion - Another unique variant with the Penetrating Legendary effect, which is awarded to the player character upon completing the quest Ablutions.

Locations

 * Frequently carried by Children of Atom on the Island, especially by Zealots in and around the Nucleus.
 * Several rifles can be found lying around in Children of Atom territory.
 * Can be purchased from weapon vendors across the Island.
 * One can be found in the cabin at Kawaketak Station.

Behind the scenes

 * Radium is a radioactive element.

Bugs
The fire rate for the various automatic receivers will read as 300 in the inventory displays (personal, container, merchant), with the correct value (90) being shown only in the workbench display. Contrary to reports based on the bugged display values, the automatic Radium rifles do not have a faster rate of fire than a minigun. It is unknown what causes or remedies this for now, but has been noted by various players.
