Full Details & Specifications

Aero Precision M4E1 Threaded Stripped Upper Receivers


Aero Precision created a new forged receiver with the M4E1 Threaded Upper Receiver.  Featuring a new angular machined design that helps it stand apart from standard mil-spec upper receivers, the M4E1 also uses a threaded set screw for retaining the forward assist.  This makes assembly much easier than trying to drive a roll pin without all the proper tooling.  A great upper for builders.

Threaded to accept a standard AR15 barrel nut, and forged from 7075-T6 Aluminum and precision machined to work with all mil-spec AR15 parts.  Available in Anodized Black or Flat Dark Earth Cerakote finish.  

Pair with an AR Gas Vent or Forward Assist, and a port door / ejection port.
