The Aero Precision M4E1 Stripped Upper Receiver in Anodized Black is a precision-forged AR-15 upper built for shooters who want a clean, modern platform without the billet price tag. Machined from 7075-T6 aluminum and finished in hard-coat anodize, this threaded upper accepts standard AR-15 barrel nuts and integrates seamlessly with mil-spec lower receivers—including Aero's own M4E1 lower. The angular, enhanced profile gives it a refined aesthetic that stands out from basic mil-spec designs while maintaining full compatibility with your existing parts and handguards.
This is a stripped receiver, meaning it ships without the port door or forward assist installed—you'll supply those components yourself. The included threaded forward assist roll pin simplifies assembly, and the M4 feedramps work with standard bolt carrier groups. Whether you're building a precision rifle, a duty gun, or a versatile hunting platform, the M4E1 upper provides a solid foundation that won't force you into proprietary ecosystems or break your budget.
The anodized black finish delivers durable protection against corrosion while maintaining a professional, no-frills appearance. Picatinny profile lines blend cleanly with Aero's Enhanced and ATLAS series handguards, so you can build a cohesive upper assembly without gaps or fitment surprises. The .250 takedown pin holes ensure compatibility with standard pins and receivers.
