Diamondhead USA Polymer Flip Up Sights

diamondhead-polymer-sights

Diamondhead USA just released their new Polymer Flip Up Sights. Known for their metal sights, their new polymer versions are a more affordable alternative that have some of the same features as their metal flip up sights. As with most other back up sights they mount to a Picatinny rail, they’re made out of a advanced polymer/composite material and weight in at just 1.2oz for the front and 1.5oz for the rear. They feature the patented Diamond-shaped apertures and housings as Diamondheads metal flip up sights as well NiteBrite Photoluminescent Inserts that can be charged with natural light or with a flashlight.

The sights are spring-loaded and deploy quickly with the push of a button. The rear sight has dual same plane long and short range apertures with .5MOA windage adjustment  and are the exact same height as A2 sights. The front sight features elevation adjustment that doesn’t require tools. However just like other front sights on the market, the front sight can’t be mounted directly onto gas blocks. The front sight retails at $49 and the rear for $69. Check them out at Diamondhead-USA.com.

    Yes, yes, yes.

  • Clint P

    Looks to be a good sight at a good price.

  • Cymond

    I’ve been curious about the Diamondhead sights, but I’d like to try before I buy. At least these are more affordable.

    • erwos

      I’d like to give ’em a try, too, especially on a rifle where I didn’t care much about having a front tritium post.

    • Drapetomanius

      My friend got the original metal sights on a Rainier Arms RUC, and they are awesome. They really do help me pick up the sights more naturally.

      They work pretty well. If you are used to more conventional sight pictures, it may take a small amount of extra practice to get used to the Diamondhead set-up, but that’s about it. I like your “try before you buy” approach — very sensible with a product you may not be familiar with.

      Hope this helps a little bit. It would also be nice to see Diamondhead come up with tritium-illuminated versions in both metal and polymer.

    when folded, what is the size difference between the magpul buis?

  • Mack

    did you mean it is bad to mount all front sights to a gas block or just polymer ones? i have noticed troy as one specifically for front site blocks but this had me confused on why they would have a special model for that.

    • Cymond

      First, most railed gas blocks are lower than the receiver rail, so you need a taller front sight. These are probably “receiver height” for use on a free-floating railed hand guard. Second, yes, polymer sights shouldn’t be mounted on the gas block due to heat.

      • Mack

        so if you have a same plane gas block your good to go? with a regular buis? but if its not same plane thats when you get the special gas block buis? i figured that was the reason for polymer.

        • Cymond

          Yes, if you have a same-plane front sight, you could mount it on a same-plane railed gas block, but heat may still be an issue.

          • Mack

            Thanks guys, thanks for clearing that all up!

        • DiverEngrSL17K

          Cymond is correct. Standard height ( regular ) BUIS for same-plane gas blocks, and extra-tall BUIS for lower gas block rails. And most polymers, regardless of height, are not advisable for front-sight gas blocks of any kind due to the heat factor. If you really, absolutely, insist on using polymer sights on a gas block ( for whatever reason ), check the manufacturer’s heat ratings first before you decide.
