Strike Industries Ultimate Dust Cover Features The Strike Industries Ultimate Dust Cover is machined from a high-density polymer that resists cracking and wear far better than the traditional stamped steel covers found on most factory AR-15 rifles. This material choice keeps the part lightweight while still standing up to the repeated opening and closing cycles the dust cover experiences during normal rifle operation. The design includes an adjustable detent set screw which owners can turn with a small flathead driver to compensate for wear on the receiver over time. This adjustability lets the shooter dial in exactly how much force is needed to pop the cover open keeping the action protected from debris without becoming difficult to manipulate. Finished in a black Texas-themed pattern this dust cover is a simple way to add a personal touch to an AR-15 build without affecting reliability. Installation is a straightforward drop-in swap for the factory dust cover requiring no permanent modification to the upper receiver. Because the part is purpose built for the AR-15 platform fit and function match the original equipment while upgrading the material and adjustability. Shooters looking to protect their action from dirt and debris while giving their rifle a distinctive look will find this cover a worthwhile upgrade.
