Armour and weapon gizmos charged with perks can be used to enhance the weapon's abilities. As a shieldbow, the augmented dark bow can hold 1 of each type of gizmo, allowing up to 4 perks. Dark bows augmented prior to 13 June 2016's update could hold two weapon gizmos; disassembling a level 2+ version or using an equipment dissolver returns one of each gizmo (it is unknown if this could be used to get a weapon-only perk on an armour gizmo).
