Kinetic Development Group’s Kinect M-Lok 3-Slot Rail Adapter is a three-slot section of Picatinny rail that can be affixed to any single M-Lok-compatible interface in just one second—and then removed again just as quickly. When pressed down into an M-Lok slot, two spring-loaded wedges inside the foot of the black anodized aluminum adapter deploy to securely grip the rail. Depressing the tongue at the base of the unit then releases the rail segment, allowing for quick removal or repositioning of an accessory. Also available in a seven-slot configuration. Price: $50. kineticdg.com.
