Radium rifle (Far Harbor)

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

Characteristics
The radium rifle is an ancient pre-war automatic carbine that has been modified to deal radiation damage.

Its regular wooden and steel rifle components have been upgraded with all manner of wiring and circuitry, among them what looks like two gamma rounds on the barrel in front of the ejection port. A crudely made dish fashioned from wire and tin foil surrounds the muzzle. This component is somewhat reminiscent of the Gamma gun and most likely the source of the radium rifle's radiation damage. Looking at the weapon from the front shows the dish's foil parts forming the well-known radiation warning symbol with the barrel representing the center point.

The radium rifle's upgrade options are largely identical to those of the Commonwealth's submachine gun, with the notable difference of requiring much higher levels of the Gun Nut and Science! perks. The weapon can therefore be regarded as a higher-tier equivalent of the submachine gun, given that its combat role and overall behaviour down to the ammo type are virtually the same. Its considerable radiation damage per shot, coupled with its very high rate of fire (on par with a minigun's with an automatic receiver installed), make it much more dangerous to regenerating enemies like Legendaries, but especially to the Sole Survivor. Players without good radiation resistance will find themselves succumbing to rad poisoning very quickly when under fire by even one radium rifle.
