Aero Precision M4E1 Assembled Upper Ar-15 7075-T6 Threaded

The Aero Precision M4E1 Threaded Upper Receiver in anodized black combines a newly angular machined design with a billet-inspired look, delivering enhanced body profiling that stands apart from standard mil-spec uppers while remaining fully compatible with all mil-spec AR-15 parts. This forged 7075-T6 upper is threaded to accept a standard AR15 barrel nut and arrives with the port door and forward assist pre-installed, plus a threaded forward assist roll pin for tool-free setup. Designed to pair seamlessly with the M4E1 Lower Receiver, it offers a cohesive, premium aesthetic at a fraction of the billet price and features a revised picatinny profile that blends effortlessly with our Enhanced and ATLAS Series Handguards. M4 Feedramps and .250 takedown pin holes ensure reliable, repeatable function through rigorous field use, while laser-engraved T-marks provide durable, fast-target reference under harsh light. This assembled upper gives you a clean, billet-look upgrade for your AR-15 platform without sacrificing compatibility or performance, making it an ideal foundation for precision builds, duty rifles, or high-end sporting setups that demand strength, consistency, and a refined, modern silhouette.
