Strike Industries Ultimate Dust Cover Flag AR-15, M4, M16 .223/5.56 3.46" Black Polymer

The Strike Industries Ultimate Dust Cover is an aftermarket ejection port cover for the AR-15, M4, and M16 platform. Billed as the world's first quick-disconnect dust cover for the AR-15, it installs and removes without taking off the barrel nut thanks to a patent-pending spring-loaded internal detent rod, making swaps and cleaning faster than with a factory cover.

This Flag cut-out version is molded from high-density nylon polymer in a black finish, measures 3.46 inches long, and weighs just 0.3 oz so it adds virtually no weight to the upper receiver. An integrated adjustable detent set screw lets you dial in tension to compensate for receiver wear and tune the opening action to your preference. Sized for .223 Remington / 5.56 NATO AR-pattern uppers, the package includes the dust cover and the installation spring.
