These handy low-profile clips were designed to be attached on the rail, against optics, lasers and other MIL-STD-1913 mounted accessories, providing a quick-index to return to the same point…especially in the dark. Each set comes complete with 72 total clips, 60 regular and 12, designed to hold tapeswitch wires along the rail’s edge. LaRue IndexClips are easy to install,and stay-put until pried off (a Dillo’s foot works really well for this, sold separately). Several clips in a row can be used to protect a length of rail,and feature a non-slip surface.
