Diamondhead USA Diamond Integrated Sighting System
The Diamond Integrated Sighting System includes the Diamond Rear Combat Sight and the Diamond Front Combat Sight. The diamond-shaped upper housing found in both sights allow the eye to rapidly place the front sight post in the exact center of the rear aperture. The diamond-shaped rear apertures gather more light to the eye, allowing for faster sight acquisition.

Solid Back-up Sighting System!

First off I want to thank PA for having exemplary customer service and fast shipping. This being my 5th purchase with consistent results I felt obligated to state this. Thank you for caring about your customer and surpassing expectations set by competitors.
<br>Now for the sights:
<br>The sights seem well built. They have a real tactile and positive lock; no rattling. The rear aperture rotates in increments and also have a positive lock-up. The materials used to construct the sights seem to be of high quality, although time will tell.
<br>The sight picture is unique to anything on the market currently and I have no doubt that whether in CQB or long distance training, that these sights will perform well.
<br>For my next AR, which will be a complete build, I will be ordering another pair of these. Thank you again PA!
Yeah, they’re fast!!!
Got these on sale to install on a AR9 upper from FM products. My son tried these sights the first time on a demo USPSA course. He was faster with these sights than another AR9 outfitted with an EOtech 512. Lives up to the fast sight picture claim. Will definitely buy another!
Good product and great price
Great price and fast delivery. Thank you PA. I got this pair BUIS for my new build and lookking forward sight them in. I'll get them again for future projects.

The sights seem to be well made and look awesome, however, both units were scratched on the bottom, makes me think i got used parts... hope not.

These sights are awesome!! I ordered on the 26th late afternoon and had them in hand on the 28th. Can't wait to take my rifle out to the range this weekend.
I See Level Lines... Everywhere. < . >
by ToneBone -
For some reason, I see the world in vertical & especially, level horizontal lines. For that reason, these sights work really well for the way I see the world, even through iron sights.
<br>The diamond shape < . > just makes aiming & centering, so fast & intuitive!
<br>A huge THANK YOU to Primary Arms for dropping the price so even I can afford them.
<br>I sighted them in with 4 shots, then topped my picatinny rail with PA 3x Compact Prism Scope. Happy! : )
Very nice product well made. Then reason it's (4) four stars it's because the button to release the sight to pop up on the front sight is little hard to push. But other than that very good!!!
These Sights are Great

Picked up these sight on sale. They are perfect. As one commentator indicated the sights are almost zeroed right out of the box. I only had to do minor adjustments. I'm very impressed and highly recommend.
Superb sights for $80.00

These sights are the best sights I have ever used.
<br>Excellent build quality, extremely serviceable and the Diamond sight picture is perfect with both my Eotech 512 and my Red dot co-witnessed.
You gotta see them to believe them. Diamond on Diamond is quick !
No doubt these are the quickest target acquisition iron sights out there. They are well built and can take abuse. I just wish they were spring activated pop ups and then they would be everything I ever asked for to back up my Aimpoint. ..Oh and their D45s are awesome for scoped applications.

Product arrived super fast. Fit right on rails and great sights. Will purchase more as needed for other builds. Thank you Priamary Arms.
Best irons for the buck
by Indiana Jones
I really love this sight set. Very close to a 50yrd zero right out of the box. Lock up is tight. No wobble. Folds down with ease. Sleek look. Couldn't be happier with these. Thanks again to Primary Arms for ridiculously fast shipping
Awesome sight system, well made
by Dwayne McIntyre
This is an extremely fast and accurate system, if a bit pricey. Overall no complaints other than they are not assisted flip up, you have to manually raise them up... first world problems...
by Mario Hernanadez
Service was super fast and items is excellent. Will be buying more from y'all.
Really great sights on my BCM keymod!
by Brian Rutherford
I just ordered these sights and of course Primary arms delivered them fast and as always has the most rocking service ever! The sights are really good so I cannot understand anything negative others might say, they are built well like troys and lock into place tight with two small ball bearings. easy to install. Same screw type like troy. They don't sit up too high but are similar to the troy system height and not lower profile micros. A tad wider on the base but smoothed out. The diamond apertures are actually better when you get them on and sight in, you can match the front to the back diamond perfect and see them well for close in and far shots beyond 600 yards. I have troys, magpul, LWRC and these are just as good as those sights easy. They are tough too and different. Mine are on a BCM 14.5 Key Upper lightweight and a Royal Arms Lower with Geiselle trigger. I don't even use a scope...Love Primary for selling sets. Neato.
Best sights money can buy!!
by Francisco Garduno1
These are the best sights I've ever bought. They are the toughest ones out there. Great sight picture no spring tension that pops them up quick that causes more wear tear.It's kinda hard to believe you got a bad set by what you said.
