Gun Knuckle (ガンナックル Gan Nakkuru) is Nove's Device-like Inherent Equipment, a state-of-the-art equipment developed by Jail Scaglietti and Uno while having Subaru Nakajima's (or, more likely, Quint's, after the Combat Cyborg Incident) Revolver Knuckle as a basis.
By the the time of ViVid, it is seen synchronized with Jet Edge during Nove's fight against Heidi E. S. Ingvalt, similar to Revolver Knuckle with Mach Caliber. It could have been upgraded into an Armed Device.
It appears as a gauntlet with an energy gun inbuilt installed on the back wrist and can fire energy bullets like a machine-gun, e.g. Gun Shooter.
