Strike Industries
The Strike Industries Enhanced Ultimate Polymer Dust Cover for AR-15 Ejection Port is a lightweight, quick-deploy protective cover built for shooters who want a durable alternative to traditional brass deflectors. Whether you're running a carbine on the range, in competition, or in the field, this dust cover keeps fouling and debris out of your action while staying fast and accessible. The high-density polymer construction is tougher than standard metal covers, resistant to wear, and designed to handle repeated opening and closing without failing.
What sets this cover apart is speed and adjustability. You can attach or detach it in just 5 to 10 seconds—no tools, no fuss—making it practical for shooters who swap configurations or need quick access to the ejection port. The adjustable detent set screw lets you fine-tune the opening resistance as the receiver wears or if you simply prefer a different feel. A small flathead driver is all you need to dial it in to your liking.
Strike Industries engineered this design with the patent-pending mechanism to be genuinely user-friendly. If you've struggled with stiff, slow-to-open covers or ones that loosen up over time, the tunable detent gives you control. It's a smart upgrade for any AR platform where reliability and ease of use matter.
