Protectron's Gaze is a unique laser gun used by the Mechanist. It bears the "rapid" legendary affix which boosts its fire rate by 25% and makes reloading 15% faster, and comes, among others, with a pistol grip and a beam splitter mod by default. The gun mirrors its Fallout 3 counterpart in terms of handling like a laser shotgun, although the older model had a slower rate of fire than its regular version instead of a faster one.

The weapon is carried as a personal weapon by the Mechanist, aka Isabel Cruz in the Mechanist's lair. It may be looted from her corpse if she is killed, or pickpocketed from her. Buying the weapon from her is also possible if she is given a better weapon and equips that instead.
