The Fortis Manufacturing Billet Dust Cover is a precision-machined replacement for your AR-15's ejection port cover. If you're running a .223/5.56 build and want to swap out the factory polymer cover for something more durable and refined, this solid aluminum upgrade delivers the form and function that sets a quality rifle apart from the rest.
Built from aircraft-grade 6061-T6 aluminum and finished with Type III hardcoat anodize, the Fortis dust cover is engineered to handle the rigors of the range, the field, or the duty rifle. Unlike polymer alternatives, billet aluminum resists wear and maintains its finish under hard use. It's mil-spec compatible, so installation into your existing AR-15 upper is straightforward—no gunsmithing required.
Made in the USA, this is one of those details that gun builders and shooters recognize: it's the small upgrades that compound into a rifle you actually enjoy using and maintaining. Weighing just 0.4 ounces, it adds durability without adding bulk.

No. The Fortis dust cover is designed as a direct replacement for your existing ejection port cover and requires no gunsmithing or special tools to install.
Type III hardcoat anodize is a mil-spec finish that creates a hard, protective oxide layer on the aluminum surface. It resists corrosion, scratching, and wear better than standard Type II anodize.
