Surefire X-300 Ultra Weapon Mounted Light - Black (500 Lumens)

The powerful, virtually indestructible X300 Ultra WeaponLight was primarily designed for handguns but is also excellent for long guns and mounts securely to MIL-STD 1913 rail-equipped rifles via its newly enhanced T-slot mounting system. This top-selling WeaponLight features a high-performance LED that generates 600 lumens of stunning white light that’s focused by a Total Internal Reflection (TIR) lens to produce a high-intensity beam with extended range yet it provides significant surround light for peripheral vision in close quarters. The highly efficient virtually failure-proof LED generates tactical-level light—ideal for close- to long-range target identification—for 1.5 hours per set of batteries.

Activating the X300 Ultra is done via intuitive, ambidextrous switches—now wider and shorter for improved ergonomics—at the rear of the body. Simply press the switch on either side for momentary-on activation or flip up or down for constant-on activation. Optional DG grip switches (for handguns) and pressure-activated XT tape switches (for long guns) permit the X300 Ultra to be activated remotely.

The X300 Ultra can be securely attached to a handgun or a long gun via its new and improved T-slot mounting system. Universal and Picatinny crossbar wedges are included for simple, foolproof installation. Its high-strength aerospace aluminum body—including the mounting system—is Mil-Spec hard anodized for superior toughness and it is O-ring sealed, making it weatherproof.
