Strike Industries AR-15 Aluminum Ultimate Dust Cover



When you need a new AR-15 dust cover, you’ll find that there are a few choices on the market. Unfortunately, they’re not all created equal, so it’s important to choose the ejection port cover that best fits your system. Many shooters would like to use custom dust covers but find that much of what is on the market isn’t what they had in mind. If you need an AR-15 dust cover and you’d rather not have a polymer version, the Strike Industries AR-15 Aluminum Ultimate Dust Cover just might be the one for you.

It’s not Flashy, It’s Purpose Built

While other manufacturers’ focus on style when they produce custom dust covers, Strike industries dust cover is more about substance. These aluminum dust covers are furnished with the spring and pin needed for installation. This dust cover is designed with an adjustable set screw that allows the user to make corrections for a worn receiver. If you prefer a lighter or stronger opening tension, the adjustability of the Strike Industries Dust Cover allows you to fine tune tension. You’re not at the mercy of production spring tension anymore. The cherry on top of the UDC is Strike’s patent-pending padding that gives you near silent operation instead of the standard clanking ejection port cover.

Quality Construction

From the integrated detent screw to the hearty aluminum cover itself, the Ultimate Dust Cover is designed in the U.S. and manufactured from quality materials you can count on. It’s given a high tech CED coating that’s finer and more durable than traditional finishes. Sleek, and quiet, the Strike Industries Ultimate Aluminum Dust Cover takes care of business without calling attention to itself and that’s just what you need.

  • Ultimate Dust Cover

    Love it. Quick and easy to install. After a little adjustment it worked like a charm. Nice and quiet when it opens. I will be getting more as i build more projects.

  • Really nice finish, minimalist look.

    I use this dust cover on all my builds, but I had to file down excess material in some areas to get it to move freely on my Aero Precision m4e1 upper, then go over it with a Sharpie to cover exposed aluminum. I hope this is not a comparability issue, cause I use Aero a lot.

  • Slick Looking Dust Cover That Opens Silently

    Posted by NATHAN CUNNINGHAM on 11th Oct 2019

    Purchased this for my S&W M&P15 Sport II as a sort of rebuild to replace the standard beat up version that's currently on there. This thing is very cool and literally took me 30 secs to get it on. The inside lip of the cover lines up and stays tight to the ejection port. The adjustable ball detent you can screw in or out to control how hard it is to snap your cover in place is nice and I'm at least able to get it shut now (make sure to put some blue loc-tite on it after it's set). They also send #4 rubber pads for the cover that you can stick on the outside bottom and it'll make all most no sound at all after opening or at least mine doesn't. If your afraid about the rubber feet not sticking then go on Amazon and buy "3M Primer 94" Tape Adhesive Promotor. I coated the pad areas in Primer 94 multiple times then stuck the rubber feet on and I really think that these pads will be on there for quite a while. I don't know how long the finish will hold up and I kinda wished I would've went with the more expensive AL billet version but overall very cool functioning and looking dust cover.

    I have purchased many Strike Industries AR accessories and I cant say enough for the looks and quality of their products! I have switched out all of my dust covers for these and the look is simply amazing! Of course buying from Wing Tactical is the only place i will do so!
