The Fortis Billet Dust Cover (brand part no. AR15DstCvr-Std-BLK) is a machined-aluminum ejection port dust cover built as an upgrade over the polymer dust cover that ships on most factory AR-15 uppers. Manufactured from a solid piece of aircraft-grade aluminum, it offers better overall durability and reliability than the plastic versions it replaces, standing up to repeated opening and closing without the cracking or wear polymer covers can show over time. It is a simple, direct install onto any mil-spec, .223/5.56 compatible AR-15 upper, giving builders a quick way to upgrade the form and function of the rifle without a full upper rebuild.
