Front and rear 45 degree offset sights that stow away under optics, and swing out at a 45 degree offset for quick use of iron sights in closer quarters.

Why is the Diamondhead D-45 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 re-styled upper housing of the rear sight makes rapid aiming even easier and for CQC aiming, target acquisition can be made with the apertures flat and by merely aligning the rear upper housing with the front sight post.

The other main reason the Diamondhead 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 proprietary Diamond-shaped upper housing eliminates 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.

5.0 Rating great - 10/15/2013
Reviewer: operator 010
Wonderful setup put my eotech and magnifer a lil farther foward than I like but only 1or 2 slot no big deal . Great fold them and there out of site then flip bam back ups on a 45 ... wen your rifle is 45'd seem to flow better between targets you don't over swing as much ... and the diamonds are the best part easy easy easy site acquisition .... way better than oem A2 round aputures , coupled with a tritium night sight up front and that's all you need

5.0 Rating ridiculously excellent - 4/12/2014
Reviewer: JDMHero47
Both my RR-15 & LR-308 have nightforce scopes for long range shooting, making the gun bad in CQ. (Real bad, 0 is @ 300m) I hate readjusting it all the time, but in case some game would appear out of nowhere I'd always have to pass on it since its not fair to the game to just blindly guess shots & not make the kill. Now for 45° offset sites, these take the cake, hands down. It's not even funny... the diamond shape of the housing makes it stupid easy to line them up quickly. Even on my first time playing with them, you instinctively line them up without having to use the peeps. For fine tuning you use the peeps, but voila, they are also diamond/square shaped, making it again ridiculously easy to align. Aside from the price tag, you can't beat these with anything else currently on the market. Before I forget, these are spring loaded too, which is a MUST have for backup sights like these. They got me a clean kill this last weekend on a goose that caught me by surprise, 50m away. Aside from the idiocy of using a rifle on waterfowl, I can attest to these being perfect for the job. Craftsmanship is top notch, my hats off to the guys at diamondhead for an incredible product!!

5.0 Rating Awesome - 4/15/2014
Reviewer: Awesome sights
Work awesome on my AR-15 with my Nikon scope. Fits perfect right underneath the scope. Haven't gotten to sight them in yet to see how accurate they are.
