With 125 peak lumens and 1-hour continuous run-time, the M3X's Shock Suppression System enables 30% greater white light output versus a standard M3 without sacrificing overall performance. The enhanced mil-spec design allows the air-tight M3X to be exposed to harsh environments from desert sand storms to 66 feet under salt water. Non-dedicated by design, the patented Slide-Lock interface provides rapid attachment/detachment to virtually any weapon with a MILSTD-1913 rail (or equivalent), while the interchangeable backplates provide multiple, user-defined, configuration options for maximum versatility. Optional backplates are sold separately.
