Diamondhead's revolutionary D-45 Integrated Sighting System takes sighting to a different level. If a fast, accurate CQC target acquisition is needed or the optic goes down, simply flip out the D-45 Sights and roll the firearm 45 degrees counter-clockwise. The D-45 Rear Sight's Diamond-shaped apertures and Diamond-shaped upper housing allow the eye to place the D-45 Front Sight's post in the exact center of the Rear Sight's aperture. The spring-loaded D-45 deploys with the push of a button and stows flat.
