Surefire X300U-B Weapon Light

Activating this light is done using the ambidextrous switches now wider and shorter for improved convenience 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.

The SureFire X300U-B can be securely attached to a handgun or a long gun via its new mounting system which incorporates a tightening screw and a T slot mounting rail. crossbar wedges are included for Universal and Picatinny rails. Its high strength aerospace aluminum body including the mounting system is Mil Spec hard anodized for superior toughness and its O ring and gasket sealed to keep out dust and moisture.

FITS:The new T slot mounting system fits most railed handguns (and rail equipped long guns) but adapter mounts are available for some non-railed handguns.
