SureFire X400U-A Tactical Light and Laser

SureFire X400U-A Weapon Light and Laser

The X400U-A represents serious tactical thinking applied to pistol and rifle mounted lighting. This is a dual-purpose tool that merges two essential combat functions into one compact package.

Lighting Performance

The heart of the X400U-A is its recoil-proof LED paired with a Total Internal Reflection (TIR) lens. Together, these components produce 1,000 lumens of illumination shaped into a hybrid beam pattern. This beam design delivers a large central spot for target identification combined with generous spill light for situational awareness. The result is an effective lighting solution for the close- to medium-range engagements where most defensive encounters occur.

Laser Aiming

The integrated 5-milliwatt laser is available in high-visibility green (515 nanometers), making it exceptionally bright and easy to see in varied lighting conditions. This laser helps you achieve rapid target acquisition and precise aiming without relying solely on iron sights or optics.

Construction and Durability

SureFire built the X400U-A from mil-spec hard-anodized aluminum. This material selection ensures the light is lightweight, exceptionally strong, and fully weatherproof. It will handle the recoil impulse of defensive firearms without degradation and maintain reliability in harsh field conditions.

Mounting

The X400U-A fits standard Picatinny rails found on virtually all modern tactical pistols and long guns. Installation is straightforward, and the light remains secure under firing.

The Bottom Line

Mounting an X400U-A on your defensive firearm sends a clear message: you take preparedness seriously. This is professional-grade equipment for those who demand reliability when it matters most.
