This SureFire light is a little over a year old and has made a trip to Afghanistan and back. It worked every time I needed it and never malfunctioned. It has a remote activator for a hand grip and an IR (infrared) filter. You can also remove the remote and use the button on the back of the light. It has a pica-tinny rail mount.
I am asking $300 shipped.
**UPDATE** Will consider trades! Throw some offers out!!
