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 adversarys 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 SureFires optional DG handgun grip switch.
