The Aero Precision M4E1-T complete upper assembly delivers a mil-spec 5.56 NATO configuration in a 16-inch mid-length gas system, compatible with standard AR-15 lower receivers. This upper is built on Aero's enhanced M4E1 threaded receiver, which features an integrated upper receiver and handguard mounting system for improved alignment and a cleaner profile. The 16-inch barrel meets the federal minimum for rifles, making this a versatile choice for general-purpose shooting, training, and home defense applications.
Machined from 7075-T6 aluminum with a Type III hard-coat anodized black finish, this upper is ready to install on any mil-spec AR-15 lower. The assembly includes a bolt carrier group and charging handle, so it arrives ready to function once mated to a compatible lower. Installation requires only standard AR-15 takedown pins—no gunsmithing needed. Verify headspace and function-check before live fire, as with any upper/lower pairing.
