Strength & Looks of "Billet," Easy Parts Compatibility of "Mil-Spec"
Aero Precision’s M4E1 Threaded Stripped Upper Receiver is ready to serve as the core of your next custom AR-15 project. It combines the benefits of Aero’s M4E1 Enhanced Upper with threads up front to accept a standard AR-15 barrel nut and handguard attachment, for those who prefer to build a rifle with a different handguard from Aero’s Gen 2 Enhanced or Atlas ’guards.
The M4E1 Threaded Stripped Upper Receiver is forged from 7075 T6 aluminum, like a regular mil-spec receiver, but with angular external contours that add the strength - and custom look - of a "billet" receiver. The good news: parts compatibility is "mil spec" all the way. The Aero Precision M4E1 Threaded Stripped Upper Receiver accepts any mil-spec AR-15 bolt/carrier group (not included) and fits on a standard AR-15 lower.
The Aero Precision M4E1 Threaded Stripped Upper Receiver comes with laser-engraved T marks on the Picatinny top rail. It gives you that badass "billet look" and robustness at a fraction of the price. And of course, it looks darned good paired up with Aero’s rugged-looking, all-business M4E1 lower receiver.
