155 customers mention "Sight quality"150 positive5 negative

Customers appreciate the sights' quality. They find them excellent, a great upgrade over stock sights, with an easy release button and pop-up feature. The profile of the sights is well-liked, and they line up nicely. The flip-up sights are amazing, even useful in daytime or lighted situations due to the NiteBrite when not in use. There is also a night sight included, which helps in low light.

83 customers mention "Build quality"73 positive10 negative

Customers appreciate the sights' build quality. They find them well-made, reliable, and durable. The spring back action feels solid and seems like it will last a long time. The polymer material is less likely to break if dropped directly on them. The sights are easy to see and line up, snapping up nicely when the button is pressed. Zeroing the sights in holds well so far, and Diamond Head is an excellent brand.

The worlds finest BUIS, and to think I bought these just on word of mouth...

The worlds finest BUIS, and to think I bought these just on word of mouth...
Not enough good can be said about these BUIS sights!!! They are solid, much more solid then the other polymer sights that are its competition... Beautiful injection molding with smooth sides... Well thought out design with the diamond shape aperture, but also the hood being diamond shaped as well to give your ling of sight that much more to go by... I got this set for my Kel Tec KSG and never been more happy with a set of sights then I am now... The spring load flip up is robust and firm, but with the button on the side instead of the front like its competitor, your not busting your thumb knuckle every time you engage it...I also love the NiteBrite glow in the dark feature on the front and rear... Its not tritium which has a shelf life, but actual glow in the dark infused into the sites itself... Which is even nice during the day time and lighted situations due to the NiteBrite when not in use just give your sights an extra advantage of alinement with the white/greenish bars...On a side note, when I received my order and was so amazed being these were better then I originally thought, I called the seller/company to just say how much I thought of their product. Very nice people. I could hear the shop in the background which tells me this company is very serious about what they do. But very plesant to talk with on the phone as well...I am going to replace all of my BUIS sights soon and use all Diamondhead. Maybe not all of them in the Polymer as they also make in metal which I will use on my ar's, but the polymer on my tactical shotguns. Either way, Im switching to all Diamondhead...

    5.0 out of 5 stars Afordable sights from some of the best in the biz
    Reviewed in the United States on January 29, 2015
    Verified Purchase
    After reading multiple accounts of Metal Back Up Sights bending while falling directly onto them (while flipped up) I decided that polymer is the way to go (as long as it is not mounted to a gas block because they will melt!) polymer is half the price and just as accurate. Plus, it doesn't bend really... it bounces back. I had wanted the metal Diamondhead sights for a while but when I saw that they had released these, it was a Godsend. I like them better than the Magpul sights (although those are very good and nothing wrong with them) because the diamond shapes really do help acquire target faster and lets face it, they look way cooler!!
    The construction is good. When you press the release button, it has a quick, positive snap into place. The rear sight that I got has a release button that isn't as smooth as the front but that doesn't hinder the function of it at all. After some use, it has gotten better. I like that the mounting bolts are flush and wont get snagged on anything. They sit down flat and don't move. They are the same height as my stock A2 sights (see pic) which makes it easy to co-witness sights (see pic) Easy to zero and I love that you do not have to have a tool to adjust the front sight post. Glow inserts work as advertised and glow for over an hour, just shine a good flashlight on it for about 5-10 seconds. That's all it takes. I would recommend these to anyone who wants some more affordable BackUps and isn't afraid of polymer. Talking to you old school!! :) Jokes aside, they all have their pros and cons. What works for you?

    5.0 out of 5 stars My favorite sights
    Reviewed in the United States on November 8, 2014
    Verified Purchase
    I own YHM, Troy micro battle sights, Magpul, and other flip up and solid sights, and I have to say, I really like these sights.
    The Diamondhead polymer sights are fast becoming my favorites.
    The diamond pattern allows for really fast sight alignment on your target.
    They were a little bit snug to slide on my rail, but feel very solid.
    Springs in mine are good and strong, you touch the button and they pop fully up with a snap sound.
    Mine lay almost perfectly flat against my rail when in the collapsed position.
    I used my laser bore sighter after I installed them on my full length rail and was very surprised at how little adjust it took to bore sight them.
    Both sights adjusted very easily, no tools needed for the front and you can use a bullet casing, coin, or a small flat screwdriver for the rear.
    Update 11/11/2014- I have to differ with the reviewer that is claiming that Magpul MBUS sights are so much better than the Diamondhead sights.
    Yes, The Magpul MBUS sights are good sights, but I found them to be harder to push down into the collapsed position than the Diamondhead's. And the release button on the Magpul MBUS sights requires more pressure to push to pop them up.
    With the MBUS sights, you need to carry a AR sight tool to adjust the front sight post, the Diamondhead front sight is tool-less and has a easy to adjust thumb wheel.
    The Magpul MBUS sights are bulkier than the Diamondhead's, which on some rifles with lightweight aluminum quad rails, can look out of place.
    But my honest comparison between some of the popular flip up sights.
    Yankee Hill Machine YHM-5040- Very easy to push release button, sights pop up well, easy to push down into the collapsed position, easy to adjust, front sight requires tool.
    Troy Micro Battle Sights HK front and round rear- A little bit stiffer to push release buttons, fairly easy to lift into upright position, fairly easy to push down into the collapsed position, easy to adjust, front requires tool.
    Magpul MBUS- Hardest to push release buttons, pop up nicely, hardest to push down to collapse, easy to adjust, front requires tool, bulky and look out of place on some lightweight rifles.
    Diamondhead- Easy to push release buttons, pop up with a snap, Easy to push down to collapse, harder to push down than the YHM but closer to the Troy's, very easy to adjust front sight, easy to adjust rear.

    Reviewed in the United States on March 29, 2016

    Let me start by saying that these are excellent sights, easy to use, quick read, easy target follow ups, seem to be well made. Solid mounting. The issue that I found was on some rail systems, the front sight will not fit properly due to the overhang from the base of the sights. I have 2 ARs that the sights fit very well with no issues, one had a traditional quad rail, the other a keymod thin rail. The other 2 ARs would not allow for the fitment of the sights, again this a combination of the rail design and the design of the sight. If the bottom edge of the front sight was tapered, or slightly smaller, I don't think it would be an issue. You could say that is the fault of the rail that the sight does not fit, and that would be true, however, if I'm Diamondhead, I'd make my sight so that it would fit as many rail designs as possible. Bottom line, if you have a traditional old school 4-side quad rail, these sights will fit like a champ, if you have some a bit different, like a keymod or M-Lok rail, you may have issues. the thing to look for is the height of the picatinny rail that runs along the top of the handguard, the taller, the better. Although it is a matter of a few thousandths, it IS enough to make a difference. Alternatively you could trim the base just a bit for clearance since it is a polymer material. I'm not at all suggesting that you stear clear of the Diamondhead sights, just be aware of their potential fitment issues. If I were to base this review solely upon the weapon that they fit, it would 5 starts and nothing but great things to say.
