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.

  • Ridiculously Quiet...

    Posted by Jason Bang on 10th Jul 2022

    After swapping out my dust cover on my ar-15 carbine... the noise level dropped by at least 1/3, when I pull on my charge. This dust cover is a must!

    Every AR needs a little bling now and then. This Dust Cover does that well. Gucci gun at its finest.

    I've purchased a number of these dust covers and have always been impressed with the quality, durability and function. My latest purchase was for the clear anodized color. It matched perfectly with my silver pins and trigger.
