Surefire X300U-B

This newly enhanced version of the SureFire X300u delivers 1,000 lumens of LED-generated output.  The throw of the light is focused by a precision TIR lens, creating a far-reaching high-intensity beam.  The throw pattern feature 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 Surefire X300u, with its T-slot thumbscrew clamp, attaches securely to any Universal and Picatinny rails found on most handguns.  Activation is done with the integral one finger ambidextrous switch.  The switch can be depressed for momentary light or flipped in either direction for constant on.  The x300u can be equipped with SureFire’s optional DG handgun grip switch.
