Fortis Manufacturing Billet Dust Cover – AR-15 / M4 Platform

The Fortis Billet Dust Cover is a precision-machined upgrade for AR-15 and M4 pattern rifles. Replacing the standard mil-spec ejection port cover, this billet component provides enhanced durability and a clean aesthetic while maintaining the critical function of keeping debris out of the upper receiver when the rifle is not in use.

Machined from billet aluminum with a carbon fiber composite construction and finished in black, this dust cover installs using standard AR-15 components. Installation is straightforward for anyone familiar with basic AR-15 assembly, though care should be taken with the C-clip and spring retention. The billet construction offers improved rigidity compared to stamped covers.
