Is this... I prefer to hold this in a neck index technique. With the advent of lights with their own picatinny rails (Nitecore P25), all kinds of practical possibilities are now possible, at long last. This is about 2600lumens, has a gen 3 Lucid HD7, and a very, very sharp Xeno bezel (aka stab-da-****kah) ring. I only need to add my Magpul MS3 sling and I'm done!
