Kinetic Development Group's Kinect M-LOK Single 3 Slot Picatinny Rail is a revolutionary QD mounting system that will change the way you attach accessories to your modular weapons platforms. The Kinect insures 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 truly removable with the ability to mount it in a second when needed. Features: Compatible with any M-LOK rail system 1.68 inches length x 0.82 inches width x 0.41 inches height Black anodized finish
