Diamondhead REAR Combat Sight - Diamond - Black - LIFETIME WARRANTY
Diamondhead's DIAMOND Combat Sights, the D-45, MICRO-D, and Gas Block Sights are an innovative design for M4/AR15 variants. When paired together, they create the Diamondhead Integrated Sighting System (I.S.S.). By incorporating the Rear Sight's original, patented Diamond-shaped Apertures & Diamondshaped Upper Housing with the Front Sight's proprietary, patented Diamond-shaped Upper Housing, the eye can place the front sight post perfectly in the center of the rear aperture. The result - "Faster Target Acquisition and Centering". Diamondhead's I.S.S. has received critical acclaim from industry writers as well as Military and Law Enforcement professionals, many of whom prefer to use the Diamondhead I.S.S. as their primary sighting system.
