Kinetic Development Group's Kinect M-LOK Harris Bipod Adapter is a revolutionary QD mounting system that will change the way you attach accessories to your modular weapons platforms. The Kinect system ensures proper and easy installation and is quite simple in its operation. There are two spring-loaded wedges in the base of the Kinect mounting point. When you press the accessory or rail section down in the M-LOK slot, two tiny deployment triggers get pressed against the rail, firing the wedges into place. This changes the whole dynamic of the M-LOK system and really makes every accessory quickly removable with the ability to mount it in a second when needed. Length - 3.73" - uses two M-LOK slots.
