The new Surefire Pro Kinect QD mount is simple and straight forward. If you have one of the new Surefire pro weapons lights with the integrated swivel adjustment mount, you can replace the included pic rail or hard mount M-LOK mount with this QD M-LOK mount. Their patented Kinect mounting system allows for easy on and off your weapon system to allow the end user to use their Surefire light on other weapons or accessories if needed. (SUREFIRE LIGHT NOT INCLUDED WITH MOUNT) The Kinect(TM) by KDG for M-LOK(TM) is a revolutionary QD mounting system that will change the way we attach accessories to our modular weapons platforms. Much like the Sidelok(TM) for picatinny attachment, Mfg: Kinetic Development Group
