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: Pros: -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) Cons: -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.
