Strike Ultimate Dust Cover Capsule AR-15/M4/M16 .223/5.56 Flat Dark Earth Polymer 3.46 in

The Strike Ultimate Dust Cover Capsule is an AR-15 / M4 / M16 ejection port cover designed for .223/5.56 AR-platform uppers, including billet upper receivers. Molded from durable polymer in a Flat Dark Earth finish, this capsule-style dust cover seals the ejection port against debris, dust, and fouling to keep the action running clean.

The Ultimate Dust Cover features an adjustable detent set screw that lets the shooter compensate for receiver wear and tune opening tension for smooth, positive ejection port function. The capsule profile keeps the cover low-profile and snag-resistant, and at 3.46" long it drops directly into the standard AR-15 / M4 / M16 dust cover channel. The Flat Dark Earth polymer finish matches the most popular FDE accessories and rifles on the market.

Built for AR-15, M4, and M16 .223/5.56 builds, this dust cover installs in place of the factory part using the included dust cover, spring, and pin. Whether you are replacing a worn factory cover, completing a custom build, or finishing out a billet upper, the Strike Ultimate Dust Cover Capsule is a straightforward drop-in upgrade.
