Diamondhead Polymer Integrated Sighting System: Faster Target Acquisition & Centering

This high-quality sighting system was designed with the modern sporting rifle and the AR15 in mind. These sights are equipped with trademark diamond-shaped apertures and upper housings for a quick and easy sight picture.

Many sights designed for low-light conditions use tritium, an isotope of hydrogen, as the illuminating element. Because tritium is radioactive, it can be mixed with a phosphor to create a continuous light source. Tritium-equipped sights, however, tend to be very expensive. The integrated sighting system by Diamondhead makes use of low-cost NiteBrite photoluminescent inserts to provide the needed illumination for the sight posts. NiteBrite is easily activated with daylight or a flashlight.

Enhance Your Shooting Experience Day and Night

This sighting system comes as a set of one front sight and one rear sight. These sights are spring-loaded for quick deployment and easy storage. They are compatible with any weapon equipped with a top picatinny rail. Elevation adjustment is easy and does not require any tools. Made from high-quality polymer, the Diamondhead Diamond Polymer Integrated Sighting System is both durable and lightweight. Consider this system to enhance your next low-light shooting experience.

  • Great set of sights

    Posted by Thanos on 8th May 2018

    Love these on my DB-15. A little snug getting on, but hold on tight once they are fitted correctly. Flip up button is quick, and lay down is easy. Looking down range just got a lot better for me.

  • I prefer the aluminum ones...

    Posted by Abs on 30th Jun 2017

    I already had the aluminum version of these sights for another build. I bought these because I think the polymer version is a little more rugged and frankly are less expensive. The things that one might identify as cons (some of them) is really a matter of trade-offs:

    -nice design (with the aiming system)
    -good build quality (accurately molded with no problems)
    -sturdy design (springs and mechanisms are solid with no play at all)
    -press button to open, fold downward to close (aluminum versions are backwards, need to press the button to close which is a bad design)

    -front sight was slightly tight on the picatinny rail and I had to tap it on with a mallet, rear was fine
    -front site release button was very stiff at first, I had to operated it about a dozen times to free it up
    -release buttons require a higher effort to open the sights than I expected, this is good and bad in that it won't open accidentally but you need to make sure to fully depress the release buttons to deploy the sights

  • Best set-up for the money

    This was my second build and I have to say that these sights are superior to the MBUS sights I put on my M5 .308. Theses sights not only allow you to get a quick sight picture and alignment but look great to boot.

  • Nice backup Iron Sights for the Colt M4

    Posted by Michael on 18th Dec 2015

    After looking and reviewing other options for the newly built Colt M4 Carbine, I decided to go with polymer integrated sighting system. The NiteBrite works quite well once you charge the system. The proof will come from the range which at the time of this review has not happened but the ease of mounting, the low profile and the light weight met my expectations.
