One of the premium back up iron sights for the AR-15 / M16, the Diamondhead Rear Sight employs a detent button to lock the sight in a deployed position – it flips up quickly for rapid deployment and folds down with the push of a button. The Diamondhead incorporates a unique diamond-shaped aperture that allows the eye to place the front post perfectly in the center of the rear aperture. Short and long range apertures are on the same plane, and at the same height as factory A2 sights. Accurate windage adjustment can be made (0.5 MoA), the small or large aperture can be active in either deployed and stowed mode, height when folded is a compact 0.435”, and it mounts to any standard dimension Picatinny rail. Construction is Mil. Spec. Stainless Steel and Type 111 black anodized 6061 T6 aircraft aluminum for combat durability. Made in the U.S.A.
Note: If you are using this sight with an A2 standard front sight base which is not an “F” marked sight base, an .040” taller sight post will be required to allow the sights to line up properly (available on our website).
