Strike Industries Ultimate Dust Cover AR-15, M4, M16 3.46" Black Polymer

The Strike Industries Ultimate Dust Cover is an upgraded replacement ejection-port cover for the AR-15, M4, and M16 upper receiver platform. Designed as a direct-fit swap for the standard factory dust cover, this Ultimate version adds an adjustable detent set screw that lets the end user tune the cover's opening tension, compensating for receiver wear and dialing in the exact amount of snap-open resistance desired.

Molded from a high-density polymer in a matte Black finish, the cover is built for light weight and excellent durability. At 3.46" long and just 3 oz, it matches the footprint of the mil-spec part it replaces and fits AR-15, M16, and M4 upper receivers, including Billet Uppers. The included hardware is everything you need for installation: the dust cover, spring, and pin come in the package so you can drop it onto your rifle right out of the box.
