Top notch lightweight grip - NcSTAR Vertical Grip for Picatinny and Weaver Type Rails

The style is nice and light and compact and it's easy to take on and off by turning the handle. It spins and extends a pin in the middle of your picatinny open rail between sections rather than grabbing either side of the rail. You will still have to slide it on from the side to start with. Works well with small and picatinny mlock rails. She makes it easy for switching back and forth between the grip or a tripod with picatinny mount.
