Be Prepared For Anything. Lightweight and compact, the SureFire XC2-B-RD securely mounts to railed handguns without hampering your handgun's concealability and delivers 300 lumens of white light plus a highly visible <5-milliwatt 635-nanometer (class iiia) laser aiming device powered by a single aaa battery. surefire's proprietary, precision-engineered smooth parabolic reflector projects a beam with a focused hot spot for mid-to-long-range illumination along with a corona of diffused light optimized for situational awareness in the near field., while the laser allows you to rapidly acquire a target without having to align your iron sights, a critical advantage if using a nonstandard shooting position is necessary. once zeroed, the laser rarely needs re-zeroing, thanks to a proven windage and elevation adjustable laser carriage and a robust rail clamp mount that will not shift under the effects of recoil. the xc2-b-rd's intuitive, ambidextrous switching provides both momentary- and constant-on activation options. its precision-machined aerospace aluminum body is mil-spec hard anodized and sealed to repel the elements. as a result, it's plenty rugged enough for everyday carry and light enough that it won't weigh you down.>
