X300U Thumb Screw

This newly enhanced version of our best-selling SureFire X300 Ultra now delivers a stunning 1,000 lumens of LED-generated output focused by a precision TIR lens, creating a far-reaching high-intensity beam — with a larger center spot — that offers the power to positively identify threats at significant distances while temporarily impairing an adversary’s vision. This intense beam also provides extensive peripheral illumination for maintaining situational awareness.

The rugged X300 Ultra with its T-slot thumbscrew clamp — attaches securely to the Universal and Picatinny rails (fitting more models than ever before) found on most handguns. As always for this best-in-class model, it features integral one- finger ambidextrous momentary- and constant-on switching and can be equipped with SureFire’s optional DG handgun grip switch. This versatile WeaponLight also attaches to the Picatinny rails on long guns — more securely than ever before and can be activated via an optional XT remote switch that gives you precision control of the light while letting you maintain a proper grip on your weapon.
