Stay True To Your Roots. The 6PX Tactical is modern and classic all at the same time. Based on the SureFire 6P that invented the compact, high-intensity flashlight over 30 years ago, it provides a single output level - a brilliant, penetrating 600-lumen beam - an aerospace Mil-Spec hard-anodized aluminum body and our classic click tailcap switch. Simply press or click to activate 600 lumens shaped by a parabolic reflector that provides a significantly far-reaching beam while maintaining ample surrounding light. With a long legacy of stopping bad guys, the 6PX Tactical is tactical perfection in its most basic form. Mfg: Surefire
