Fortis Manufacturing Billet Dust Cover - Precision Fit and Durable Design

The Fortis Manufacturing Billet Dust Cover is a rugged ejection port cover built for AR15 rifles that demand solid construction over plastic compromises. Machined from aircraft-grade aluminum, this billet dust cover upgrades your mil-spec AR upper with durability and clean aesthetics—the kind of upgrade that feels right the moment you handle it. If you're running a .223/5.56 build and tired of flimsy polymer covers that rattle or crack, this is the no-nonsense alternative.

Installation is straightforward on any standard AR15 upper receiver. The cover ships complete with the spring and C-clip hardware you need, so there's no hunting for parts or compatibility headaches. The Type III hardcoat anodize finish resists wear and corrosion, holding up to the wear and tear of range sessions, hunting trips, and hard use in the field. At just 0.4 ounces, it adds virtually no weight to your rifle while adding real durability where it counts.

Made in the USA by Fortis Manufacturing, this billet dust cover represents honest engineering: a small part done right. Whether you're building a precision rifle, upgrading a duty gun, or simply refusing to accept polymer where aluminum belongs, this cover does one job and does it well.
