WHY IS THE DIAMONDHEAD™ INTEGRATED SIGHTING SYSTEM FASTER AND MORE ACCURATE?
During high speed, high stress shooting, the eye needs reference points. The Diamondhead™ Integrated Sighting System provides them. The conventional rear sight's round aperture and round (HK style) front sight housing, can make shooting at longer distances difficult and inaccurate. Remember, rear sights are blurry during aiming. The simple fact is that it is easier for the eye to find the exact center of a blurry diamond than the exact center of a blurry circle. It is even easier and quicker for the eye to find the exact center of a Diamondhead™ rear sight’s aperture with the added posts at the corner of the diamond. These proprietary reference posts are unique to the Diamondhead™ sight and are not found on any other iron sight.

The other main reason the Diamondhead™ (Pat. & Pat. Pend.) diamond-shaped aperture is better than a conventional round aperture is because round apertures don’t give a truly ROUND picture of the front sight and target. The front sight tower of the rifle obscures the bottom portion of the conventional rear sight round aperture. This causes the the bottom part of the round aperture to be flattened – not round. The result is that it is harder for the eye to quickly make an accurate decision about how high up in this flattened circle is the exact center. Take a look at a set of conventional (round) sights to see.

The 3:00 o’clock and 9:00 o’clock corners of the Diamondhead™ aperture, combined with the added accuracy of the reference posts, completely eliminate this problem. Used in combination with the Diamondhead DIAMOND Flip-Up Front Combat Sight™ or the Diamondhead “Auto-Ranger” Flip-Up Front Combat Sight™, there will always be a clear reference for considerably more accurate (and faster) target acquisition.
