Dude, Gungnir's skin is unique technically. Apoc/Annihilator/Spharai/ were originally the "Rune Scythe, Rune Gun, Rune Cesti" models they they just made into relics. Compare the markings on the weapon and their gold color to the other Rune weapons. Be glad Gungnir is a unique model and not just a Rune Trident renamed into Gungnir.
