SUREFIRE X400U-A BLK 1000LM W/LSR X400U-A-RD

The Surefire X400U-A BLK is a high-performance weapon light designed for both pistols and long guns. Delivering an impressive 1000 lumens of white light, this compact unit offers excellent illumination with a specialized TIR lens that ensures a balanced beam pattern suitable for various low-light applications. Integrated within the X400U-A is a 5-milliwatt red laser sight, engineered to provide precise aiming assistance and maintain zero even under recoil, thanks to its secure Nylok adjustment screws.

Constructed from aerospace-grade aluminum and finished with a Mil-Spec hard anodized coating, the Surefire X400U-A combines durability with weather resistance through O-ring and gasket sealing. The light attaches quickly and securely to Universal and Picatinny rails, allowing for versatile mounting options. Ambidextrous controls offer convenient activation with momentary or constant-on modes, and optional grip or pressure-pad switches are available to tailor operation to user preferences.
