Strike Industries AR-15 Aluminum Ultimate Dust Cover

Details:

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.

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.
