Brand new Surefire HL1. It didn't interface with my helmet the way I wanted it to (I'm running a fast without arc rails cuz I like to be different. Arc rail adapters are available) but it fits any MICH series or LWH perfectly. Mount is the Second Gen Swivel version, which locks into place with a solid clip. Rotates 360 degrees. Has White and Blue led's with IR strobe option as well. Can meet around Oceanside CA. Will ship for +5$ PayPal or Cash
