Trade in Process so no longer available This laser mounts to a Picatinny rail and has an integral rail to mount a light below it. The unit comes with all original accessories including the OtterBox and dissasemly/adjustment tool. It has the touch switch with 6" cord attached to the unit. Also included is a spare battery cover, extra velcro and the standard switch if you do not want the touch switch. I bought this used and did not mount it, and the unit appears to have never been mounted. Works great and is brighter in daylight than a red laser. Retail value of this package is over $400. Will sell for $330, $335 shipped. Note: Will send pic by email if you are interested.
