Product Description
The Fortis Billet Upper Receiver is a precision-machined AR-15 upper built from billet 7075-T6 aircraft-grade aluminum for outstanding rigidity and durability. Designed with both function and aesthetics in mind, it removes excess material where possible to reduce weight without sacrificing strength. This stripped M4-style upper features M4 feed ramps, a 1913 Picatinny flat-top rail for optics and accessories, and a military specification Type III hard coat anodized finish for long-lasting wear resistance. Engraved Fortis logos on both sides and the top complete the clean, purpose-built look.
