The Polymer Diamond Integrated Sighting System is an ultra-lightweight alternative to the Diamond Combat Sights. Reliable, durable, and accurate, diamond-shaped apertures and upper housing allow the eye to rapidly place the front sight post in the exact center of the rear aperture.
Featuring NiteBrite photoluminescent inserts, this low-cost alternative to tritium sights help in low-light conditions and can be charged by natural light or with a flashlight.
Note: Due to heat issues, the front sight is not suitable for railed gas block installation.

Ratings & Reviews
Great sight picture
by jay -
The sight picture is great, they hold zero and are durable, knocked off a star because the elevation adjustment spins freely and doesnt lock in to place, the night sights only activate when they been exposed to light which kind of makes them useless. When on sale they are a better option i really love the diamond picture

Love these sights. So much so, that going back to regular BUIS on another rifle is just not easy. The points on the rear sight and the angles on the surrounds help a ton to keep consistent groupings. I have both FDE and black, and I have no troubles lining up the sights on both, but as another reviewer mentions, the FDE's may be a little tougher to line up for some folks so keep that in mind. Only 2 minor negatives keeping it from 5 stars: #1 is that the night glow doesn't really work at all on both FDE & black sets that I received. Not a biggie though for me. #2 is that on the rear sights (both black & FDE), I had to shave off some of the polymer on the bottom of the flip-up-sight part because it was rubbing on the pic rail and wouldn't flip up fully, would get stuck about half way and then I'd have to push it up the rest of the way. After shaving off a bit with a razor, it flips up freely now.<br>Overall though, these are awesome sights. Get 'em!

I just put the sights on my firearm just tried them out at 25 yards and I’m pleased with them I will update when I sight them at a longer range. The target I was shooting at was the size of my palm.
Nice BUIS...Interesting Design...
by Rodney F.
Yeah they do look different, and at initial purchase and install, I would say they do draw your eyes/sight picture to focus quickly. The glow-in-the-dark feature is nice but nothing to write home about. Got this on sale with free s/h and got it in Cali (2) days after ordering.
Great sites but....

Diamondhead sights are great. Line up the diamonds, with the post on target. Pull the trigger. Very accurate and easy to use and acquire. Better than ring sights. I have 2 sets in black, one in FDE. the FDE are harder to use I find due to the lack of contrast. The night glow is excellent. The pop up fast and fold down easy. You can easily find a pair under $100 and they are worth it, just stay away from FDE.
Good sights for the price
by Rob K.
I was only inclined to buy these sights because they were on a special at %43 off. I'm not entirely sure I would be happy with them if I had paid full price. The Nite Brite is glow in the dark paint and needs to be light charged prior to using them. I have not mounted them as of yet, but I think they will serve their purpose as back-up sights just fine.
Good sights, good price.
They look nice. They match the rest of my FDE furniture, so it fits right in. The night sights are a bit difficult to see and dim rather quickly, but aside from that, these are great.

great product, good value and excellent service from primary arms
Killer deal and great service!
by Gavin Tomeny
Primary arms was running an amazing deal on some Diamondhead Sights. I placed my order and they shipped that day! Great experience!
good backup sight
Great sight, the only problem is the springs on them seem to be a little weak. They have a side button to push to activate. If you could combine this sights top with the bottom of the Magpul you would have the perfect backup sight!
