The Echo Arms Helmet Light utilizes an integrated Magpul M-LOK interface to mount directly to the Fast Attach Mount. This bolt-on design allows the light to sit much lower than any light mounted on a 1913 rail. The integrated mount eliminates unneeded bolts and hardware that are heavy, come loose and prone to rust.
With the Helmet Light sharing the same tailswitch, battery and head as the Surefire M300 Scout, pairing the Helmet Light with a Surefire M300 weaponlight provides a backup solution in the event a weaponlight fails and needs replacement parts.
This product features the Surefire KM1-E Vampire head, powered by one 123A lithium battery, producing 250 lumens of brilliant white light or 100 milliwatts of invisible infrared output for use with night vision devices — with no need for IR filters or spare lamps.
Complete lights are available in black or coyote with the Malkoff E1 Hyper head can be found here. The body only without head or tail is available here.
