Strike Industries AR-15 Billet Ultimate Dust Cover


Have you ever taken a load of sand, mud or sticks into your AR after taking an embarrassing fall? Well, if you shoot long enough, you will. When your day is cut short by such an avoidable accident, you will see the necessity of a dust cover. There's no doubt that a heavy-duty aluminum dust cover is more than an upgrade, it's a necessity.

Internal Insurance

Most dust covers are not much more than a flimsy, stamped piece of steel that more or less covers your AR's ejection port. However, a Strike Industries Ultimate aluminum dust cover takes this to the next level. It adds a cost-effective, custom touch to your AR that seals the deal. Strike Industries has machined a durable, solid aluminum ridge seal onto the inside of your new dust cover. This greatly lessens the opportunity for crud to find its way inside of your weapon. That way you can spend your time shooting, instead of tearing down your rifle to clean it out.

Out On The Range, It Arose Such A Clatter

Let's face it, unless you are running a brand new custom gun, an AR is going to make some noise when it cycles. The Strike Industries Ultimate aluminum dust cover wears patent pending rubber pads on its lower, outer edge. When your dust cover flies open on that first shot, it slams down onto your receiver. These durable, rubber pads serve to cushion that impact. This not only reduces the noise of opening, but it saves excess wear to your dust cover and your receiver as well. It installs in seconds, opens with a whisper, and protects your AR for a very long time.

    Great quality, well built, easy to install. The only issue I had was I ordered the FDE color, but its more of a shiny, almost sparkly gold instead of flat dark earth. Other than the color being a little off, it's a nice dust cover.

    The Blue anodized dust cover was exactly what i saw on the website. I would recommend this product!

  • Great quality

    One of the best Billet dust covers on the market. Amazing detail and finish. Very Lightweight and strong! I will be buying more of these very soon

  • I wanted a different look to my rifle. I found out about Strike Industries and saw what they had and thought those would look good on my rifle. But the red dust cover was really hard to find! Until I found it with you!! It is really easy to insta

  • Looks cool!

    Lets face it. We don’t buy this for silence. The sound of the spring and BCG charging it through the buffer tube will surpass the tiny sound of a mil spec dust cover hitting the lower receiver. We buy it for looks and it looks awesome. The reason I gave 4 stars is because when I close it it hits the brass deflector before it closes. I have to push it forward in order to close without hitting it. But then again that could be the BCM upper receiver’s fault. Regardless I would buy it for every AR I build. I give 4.8 stars.

  • Nice concept

    This is a pretty ingenious dust cover, is well made, and looks great. On the mfg website, it says that the cover won't fit Aero Precision M4E1 uppers... well, it also won't fit Givati uppers. Even after adjustment of the detent from one extreme to the other, I could never get the dust cover to stay closed. Hopefully I won't have that problem if I use it on another build.

    It looks good, is easy to install and is definitely quiet when it opens. 4 Stars because you can easily open the cover (even after adjusting the tension of the ‘ball lock’) by pushing in the cover at the bottom.
