Be Prepared For Anything. Lightweight and compact, the SureFire XC2-B securely mounts to railed handguns without hampering your handgun's concealability and delivers 300 lumens of white light plus a highly visible <5-milliWatt (Class IIIa) laser aiming device powered by a single AAA battery. Our 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'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.
