The SureFire M340V is an excellent option for rifles and sub guns that need white light and IR illuminator capability. The head of the light twists into one of three positions: White Light, OFF, and IR Illuminator. This is an update to the old M300V in that it includes the SureFire PRO mounting system which can swivel into the rail, making your rifle set up a bit more sleek and tight.

The M340V is also an excellent option for mounting on helmets. The bright IR light makes for good umbrella lighting indoors, but is also great when paired with a focus or “pin hole” cap. The IR Light that comes from the M340V is bright enough to compensate for the darker image that you typically get from using a focus cap, which is nice because it allows you to see things up close without having to adjust the focus ring on your night vision.


One SureFire M340V Scout Light comprised of the following: MH31 body + mounting hardware (both MIL-STD-1913 & M-LOK) + Z68 tailcap + KM1-E infrared / white LED bezel; one 123A lithium battery; and one Allen wrench
