Protect your AR-15 from Weather and Debris

Strike Industries' patent-pending "true seal" design, combined with a double injected soft rubber sealing lip, seals the port more effectively than other dust covers, which protects your AR-15 from water and debris that could be encountered in the field.

Built to Last

This Overmolded UDC is made of a custom blend of SI polymer extreme, which is strong and impact resistant. This material does not bend out of shape or deform and is resistant to rust, making it the ideal material to stand up to the long-term use of serious shooters.

The Strike Industries Overmolded Ultimate Dust Cover also features a detent set screw that is adjustable, which compensates for upper receiver wear.

  • Strike Industries AR-15 Overmolded Ultmiate Dust Cover

    Posted by Brian McKinny on 13th Jun 2022

    This is absolutely, without a doubt, the best dust cover for AR-15s I've ever seen in all my years as a hobbyist and later as a gunsmith. I will not buy another dust cover for any of my personal AR-15 builds, and I will suggest to my customers for whom I am building a custom rifle that they go with Strike Industries for their dust cover, as well as several other Strike Industries parts I've bought and used on my personal rifles and pistols. Strike Industries simply makes excellent aftermarket parts that meet or (often) exceeds mil-spec standards. The quality of their products is impeccable, and without question they make excellent parts, and their customer service is second to none. I wouldn't hesitate to recommend Strike Industries products to any of my clients, friends, or family for any of their firearms accessories needs, and that's a fact. I've got a pretty high bar for standards when it comes to what goes into my personal builds, and especially those of my clients.
