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.

  • Very nice

    Super easy install, looks much better than mil-spec steel cover. Really sets my rifle apart from every other one out there.

    This is my favorite ejection post door! I used to like Strike’s polymer ones as well but this is just the best of all worlds. Aluminum for those who don’t like the idea of plastic, aesthetically pleasing, looks clean on your very high end build as well as your truck gun. Easy to put in and take off with no c clips etc or having to take off your handguard with certain ones ... it’s just a port door cover but it is doing it in inexpensive style. Definitely an automatic choice for all my builds.

  • Best DC Ever

    Love this dust cover, fits perfect, looks great, & went ahead and added all 4 rubber feet which made it dang neat silently.

  • Absolutely love this thing.

    This was the last thing I replaced on a stock PSA AR. With the usual Magpul and Strike Industries upgrades, the original dust cover just felt out of place and chintzy. This was a nice finishing touch and ridiculously easy to install.

  • Great idea done well

    Why didn't somebody think of this sooner? I love being able to remove (or if necessary replace) the ejection port cover without removing the handguard and possibly barrel nut. I also like that it comes with bumper pads to silence the "click" when it pops open - great idea on a rifle used for hunting. It works great on my Anderson upper, and it at least appears that the design and the inner lip is likely a little more effective than the original at keeping crud out when closed. Don't know if what would recommend the aluminum over the plastic one, but it sure looks awesome and since they're so easy to change you could get both and run whichever one you feel like that day!

  • Must have

    These things are awesome, breeze to install/remove and look killer. To top it off they are super quite with bumpers installed.
