Overview
The Aero Precision Complete Upper Receiver M4E1-T is designed for builders looking for a reliable and versatile upper that features an 18-inch barrel chambered in 5.56 NATO. This complete assembly utilizes a rifle-length gas system, optimizing gas flow for smoother cycling and reduced recoil, while the 1:7 twist rate ensures stability for a wide range of bullet weights. Commonly found in mid-length and precision-oriented builds, this upper receiver is finished in FDE for a tactical look that complements various lower receivers.
