Buy on Ammo Depot

The SureFire X400U-A pairs a 1000-lumen LED with a 5mW green laser in a single rail-mounted unit, giving shooters both bright illumination and a highly visible aiming point. Its TIR lens shapes the beam for tactical use, while ambidextrous momentary and constant-on switching keeps operation intuitive for both left- and right-handed shooters.

Built from Mil-Spec hard-anodized aluminum, the X400U-A is weatherproof and recoil-proof, and it mounts to universal and Picatinny rails on pistols and long guns. The light also accepts optional DG and XT remote switches for remote activation.
