Description
The SureFire X400U-A Ultra Weapon Light pairs SureFire's 1000-lumen Ultra weapon light with an integrated green laser — combining a wide, far-reaching beam (11,300 candela) with a fast aiming reference for handgun platforms.
Three modes (light, laser, or light + laser) cover any scenario, the Rail-Lock system clamps securely without hands forward of the muzzle, and ambidextrous switches give intuitive control. Aerospace-aluminium body, O-ring sealed (IPX7).
