Radium rifle (Far Harbor)

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

Characteristics
The radium rifle is a pre-War 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 sets of gamma rounds on the barrel in front of the ejection port. A crudely made dish fashioned from wire and tin foil surrounds the muzzle on long barreled variants. This component is somewhat reminiscent of the gamma gun and most likely the source of the radium rifle's radiation damage. With the ported variant of the long barrel, 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.

It utilizes a gas-delayed blowback design, where the bolt is never locked, and is pushed rearwards by the expanding propellant gases, which are vented from the barrel into a cylinder that delays the opening of the bolt.

The radium rifle's upgrade options are largely identical to those of the Commonwealth's combat rifle, with the notable difference of requiring much higher levels of the Gun Nut and Science! perks. Its considerable radiation damage per shot, coupled with its very high rate of fire whilst using a variant of the automatic receiver (on par with a minigun's), make it much more dangerous to regenerating enemies like Legendaries, but especially to the Sole Survivor. People without good radiation resistance will succumb to rad poisoning very quickly when under fire from even one radium rifle.

Default Radium rifle has obstructive iron sights with protruding components; Automatic variants have high recoil; The weapon suffers from a slow reload speed. Though these are largely remedied by weapon modifications.
