Diamondhead’s DIAMOND Flip-Up Rear Sight’s revolutionary design incorporates the original and proprietary Diamond-Shaped Apertures™ (Pat. & Pat. Pend.) - allowing the eye to place the front sight post in the exact center of the rear aperture… faster and with greater precision.  The DIAMOND sight has a very low folded height of 0.435” and is compatible with all Mil. Std. M1913 Picatinny rail systems.

WHY IS THE DIAMONDHEAD™ REAR SIGHT FASTER AND MORE ACCURATE? During high speed, high stress shooting, your eye needs reference points. The Diamondhead™ provides them. The conventional round aperture makes shooting at longer distances difficult and inaccurate. Remember, rear sights are blurry during aiming. The simple fact is that it is easier for your 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.) diamond shaped aperture is better than a conventional round aperture is because round apertures don’t give you a truly ROUND picture of the front sight and target. The front sight tower of your 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 hard for your eye to quickly make an accurate decision about how high up in this flattened circle is the exact center. Take a look at your own sights and you’ll 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. When used in combination with the Diamondhead Premium Flip-Up Front Combat Sight™ and the Diamondhead Premium Flip-Up Front “Auto-Ranger” Combat Sight™, you’ll always have a clear reference for considerably more accurate target acquisition.
