**Might not fit properly with some billet upper receivers.
The Fortis Manufacturing aluminum dust cover is cut from a solid piece of aircraft-grade aluminum to be both durable and dependable. The aluminum ejection port cover is designed to cover the ejection port completely when the gun is not being fired to prevent debris from entering the action. The dust cover will fit a wide variety of .223/5.56 compatible billet upper receiver builds and Mil-Spec AR15 uppers.
The Fortis Manufacturing aluminum dust cover completely seals the firearm’s election port to keep debris from accidentally entering into the action while participating in crawling drills and stalking through the brush. The aluminum ejection port cover is made to quickly and completely fall away from the ejection port when the rifle is charged. It provides an unobstructed path for spent casings to exit the port.
Made from a single solid piece of Billet 6061-T6 aircraft-grade aluminum, the Fortis Manufacturing aluminum ejection port cover is more durable than many of the polymer-based covers on the market. Weighing in at less than half an ounce, this dust cover won’t add any noticeable weight to the receiver. The Type III hardcoat anodized finish protects the dust cover from marring.
The Fortis Manufacturing Aluminum Dust Cover comes with all the pieces required for simple and easy installation, with nothing else to buy. The package includes the dust cover, the dust cover rod, dust cover spring, and C-clip. Note that while the Fortis Manufacturing aluminum dust cover has been tested on a wide variety of uppers, it is not guaranteed to fit all applications.
