Aero Precision M4E1 Enhanced Assembled Upper Receiver

Features

The Aero Precision M4E1 Enhanced Assembled Upper Receiver is a one-piece design that combines the handguard mounting platform with the upper receiver itself. This superior engineering ensures a more rigid and consistent design, eliminating the need for traditional barrel nut threads. The once-piece mounting system reduces the total number of components putting force on the barrel, providing a true free-float design. This upper receiver is compatible with most AR15 pattern barrel nuts and handguards on the market, offering a wide range of customization options. It is precision machined to work with all mil-spec AR15 parts and includes the port door and forward assist pre-installed.

The M4E1 Enhanced Upper Receiver is designed to pair perfectly with the new M4E1 Lower Receiver, offering a billet-like appearance at a fraction of the billet price. This upper receiver features a new angular machined design that enhances its aesthetics. The enhanced forging gives the upper receiver a "billet look," which blends seamlessly with Aero Precision's Enhanced and ATLAS Series Handguards. Additionally, it includes M4 feedramps, .250 takedown pin holes, laser-engraved T-marks, and a threaded forward assist roll pin.
